TSA Rules for Vapes and e-Cigarettes (The Big Questions Answered) [2023]

As people return to traveling, a lot of passengers will be asking about the TSA rules for vapes, mods, and e-cigarettes.

The rules are relatively straightforward but there are some specific requirements that you need to be aware of when it comes to things like cartridges and batteries.

In this article, I’ll break down everything you need to know about bringing your vape pens or e-cigarettes through airport security.

What are the TSA rules for vapes and e-cigarettes?

TSA allows passengers to bring electronic cigarettes and similar devices (vaporizers, vape pens, mods, atomizers, and electronic nicotine delivery systems) through airport security as a carry-on.

However, these devices are prohibited in CHECKED baggage.

The FAA banned e-cigarettes in checked luggage in 2016 after there were reports of small fires that broke out in the cargo holds. So this restriction is for the safety of all passengers and crew.

Please do not attempt to get around this restriction as it will put everybody at risk.

Bringing vapes and e-cigarettes through airport security

When taking your vapes and e-cigarettes through the airport, you can bring them inside your carry-on or inside a personal item (such as a backpack) no problem.

(I don’t recommend putting them in your pocket while in the airport because you might forget as you go through airport security scanners.)

Some airlines, such as American Airlines and Delta, recommended that you store them in a designated carry case that may have come with the original vape packaging.

If your mod/vaping device has multiple parts then it is recommended that you disassemble your vaporizer prior to entering the security line.

Even better is if you have all of the parts (atomizer, tank, mouth piece, batteries, etc.) neatly placed within a carrier for easy inspection.

When you are actually going through security, it’s recommended to remove your e-cigarette/vape, place it in a tray/bin, and put it through the x-ray scanner separately from your carry-on bag.

If you keep it in your bag, it could look suspicious and cause you to undergo additional screening.

Generally speaking, the larger your device the greater your chances of a TSA agent wanting to take a closer look.

If they want to take a closer inspection, just let them do their thing. If you don’t have any illegal substances, you don’t have anything to worry about.

Note that if you are bringing special pods or packs that contain liquid vape you need to comply with the liquids rule which I will talk about below.

Remove your vaping device from your carry-on when going through security for a smooth experience.

Liquid vape cartridges

Liquid cartridges such as JUULpods that click into the top of the JUUL devices and other similar containers that contain e “juices” are considered a liquid and, therefore, they will be subject to the TSA liquids 3-1-1 rule.

The liquids 3-1-1 rule requires all liquid containers to be 3.4 ounces (100ml) or smaller and for them to be stored in a quart sized bag (preferably a clear Ziploc bag).

This means that if you are transporting JUULpods or other juice packs, you need to transport them in a very specific way.

First, the vape cartridges need to be smaller than 100ml.

Many vape juice cartridges are much smaller than 100ml so it should not be difficult for you to find TSA compliant vape cartridges.

In some cases you may need to remove your vape cartridge from your device so that the device has no attachments containing liquid.

Second, you need to place these cartridges in a quart sized Ziploc bag.

The key thing here is that the cartridges must fit “comfortably” inside the bag which means the bag cannot be overstuffed or almost bursting at the seams.

If you do not have TSA Pre-Check, you will need to remove your liquids bag from your carry-on as you make your way through the airport screening process.

Because of this screening process you might be better off just transporting your pods in your checked baggage where you can transport unlimited quantities.

There are reports of the pods leaking at high altitudes so having them in a sealed bag is highly recommended. It is also better to transport a partially used cartridge that has room for the liquid to expand to avoid leakage.

Checking your bag at the gate

Sometimes your plane may not have room for your carry-on, especially if you are towards the back of the boarding process.

If this happens to you and you are traveling with your vape, be sure that you remove your vape and batteries from your carry-on bag that they are checking because they will not be allowed as a checked item.

Vape pen chargers

If you are bringing a power charger or power bank that contains a lithium ion battery it must also be packed in your carry-on bag.

This is because such battery packs can cause risks of explosions and fires in the cargo hold. So to be on the safe side, bring your spare batteries with you on your carry-on.

Keep in mind that TSA can apply extra scrutiny when traveling with multiple spare batteries because the batteries can pose a risk. This is especially true if your lithium batteries have more than 100 watt hours.

For that reason, you may want to only travel with one spare battery or pack your multiple batteries delicately so that they cannot come in to contact with each other.

Flying with marijuana/THC vapes

With the growing legalization of marijuana in different states, a lot of travelers are now curious as to how they can legally fly when carrying marijuana on them.

The first thing to note is that marijuana is still illegal on the federal level which makes it illegal to fly with.

Reportedly, regardless of what airport you are departing, TSA’s response to finding marijuana will be the same.

“It is important for me to note that TSA’s response to the discovery of marijuana is the same in every state and at every airport – regardless of whether marijuana has been or is going to be legalized,” TSA spokesperson Lorie Dankers explained.

“This also covers medical marijuana.”

But in practice it’s not clear that this is the case.

If you are flying from a state that has legal marijuana, such as Colorado, and you were caught with marijuana at the airport, it is possible that they will simply request for you to dispose of the cannabis.

But if you were traveling from an area where marijuana is not legalized, the response could be much different.

The bottom line is that this is still a bit of a gray area that is still developing and so there are basically no guarantees as to how TSA will react upon finding marijuana in your possession during the security screening process.

The second thing to note is that TSA is not actively looking to discover marijuana or other illegal drugs that might be in your possession. The TSA website states:

TSA’s screening procedures are focused on security and are designed to detect potential threats to aviation and passengers. Accordingly, TSA security officers do not search for marijuana or other illegal drugs

However, they do note that if illegal substances are discovered during the security screening process the TSA will refer the matter to a law-enforcement officer.

Many vapes containing THC are pretty discreet so they may not always be easily detected.

So if you are traveling with (small amounts) of marijuana/THC vape pens you may not encounter any problems but you should be prepared to have to dispose of your marijuana if it is detected by TSA and in a worst-case scenario, be prepared to explain why you have it in your possession to a law-enforcement officer.

The back up plan

Some travelers who are weary about losing items when going through security will bring a self-addressed envelope with postage so that they can mail off any item that would be confiscated.

I’ve personally never tried this before but I have seen reports online of people doing it successfully. While a rare occurrence, it could come in handy when a TSA agent uses discretion to confiscate your vape due to some unknown reason or suspicion (TSA agents have discretion to prevent you from bringing items through security).

I don’t see any reason why the self-addressed envelope route could not work in many instances but if you are trying to mail off illegal substances such as marijuana then it could obviously be very problematic (and illegal) so use common sense.

TSA rules for vapes FAQ

Can you vape in an airplane?

No, you are not allowed to vape inside an aircraft. This is to protect people from the devices’ second-hand vapor and to reduce the risk of a device malfunctioning. If you are caught vaping on a plane you could be subject to a large fine up to $4,000.

Do I need to turn my vape off during flight?

Many airlines require your vape to be turned off or to be placed in safety mode during flight.

Can you vape in an airplane lavatory?

No, you are not allowed to vape anywhere inside an aircraft.

Can I bring an e-cigarette as a carry-on?

Yes, e-cigarettes are allowed to be brought on a plane as a carry-on.

Why are vape pens not allowed and checked baggage?

Vape pens are not allowed in checked baggage because they present a hazardous risk. The batteries could be prone to exploding and catching fire in the cargo compartment.

Can you charge an e-cigarette in an airplane?

Many airlines will not allow you to charge an e-cigarette during flight and may require it to be powered off. You can ask a flight attendant but be prepared for them to tell you no.

Can I bring an e-cigarette on an international flight?

Some countries have banned e-cigarettes from flights and from importation so before attempting to travel with an e-cigarette on an international flight you should first verify that possession of the e-cigarette in the country is legal.

Can I travel with a vape containing THC?

While TSA does not actively seek out vapes containing THC, it is possible that if it is detected they will request for you to throw it out or refer you to airport authorities. This can even occur when departing from a state with legalized marijuana.

Do I have to declare my electronic cigarette?

No, you do not have to declare your electronic cigarette or vape. However, you should remove it from your carry-on and comply with the liquids rule if needed.

Do vapes leak on airplanes?

Cartridges containing liquids tend to leak at high altitudes as the liquid expands under the decreased air pressure. So it is recommended to not carry cartridges that are full with e-liquid. In addition, storing them in a sealed bag or container could be a good idea.

Can vapes set off the smoke alarm in a plane?

Yes, vapor can set off the smoke alarm on a plane which is another reason why you do not want to vape on a plane. Passengers have gotten into trouble with this in the past, so it’s something you don’t want to risk.

Final word

Traveling with an e-cigarette or vape through airport security is permitted so long as you comply with the liquid rules.

You want to pay extra attention to make sure you do not leave your cigarettes in your checked baggage because that could present major risks to the flight and also get you into legal trouble.

TSA Medication Rules for Flying on Planes [2023]

Traveling through airport security can already be a pretty nerve-racking experience. But when you are also worried about getting your necessary medical items through security and onto a plane for a flight, it can be even more anxiety inducing. Luckily, there are some pretty lenient TSA rules and guidelines when it comes to flying with your medication.

In this article, I will tell you everything you need to know about TSA medication rules and flying on a plane with medication. I’ll go over the rules for things like prescription medications, pills and liquid medication and other situations like over the counter (OTC) drugs.

What are the TSA rules for flying with medication on a plane?

TSA will allow you to travel with your medication but there are some restrictions that you need to be aware of, especially if brining medical liquids. Below, I will go through some of the most common restrictions that might apply to you and tell you how you can go about them when flying with medication.

Does TSA have a limit on the amount of medication I can bring on a plane?

TSA does not have a limit on the amount of medication that you can bring on a plane whenever the medication is in solid form, such as pills. So if you have a need to travel with multiple bottles of pills then you should not be limited to a certain amounts of pills or bottles.

If you have an outrageous amount of medication on you then you might be subject to additional screening. However, in many cases as long as they can x-ray your medication they will not require you to undergo additional screening.

If you do not want your medication exposed to the x-ray machine then just let the TSA agent knows this and they will allow you to go through a different type of screening (note that this could take more time and require you to open up all of your bottles).

Note: Medical Nitroglycerin medicines are allowed.

Tablets and pills — You can bring your medication in pill or solid form in “unlimited amounts” as long as it is screened.

What are the TSA rules for traveling with liquid medication on a plane?

If you are not aware, TSA has a rule that forbids you from bringing in liquids than can’t fit in 3.4 ounce containers. Also, these containers must fit into a quart size bag (typically a clear Ziploc bag).

This is known as the “TSA 3-1-1 rule” and you will be required to remove the bag from your carry-on unless you have TSA Pre-Check (which I highly recommend).

TSA does not enforce the liquids rule for medically required liquids (and gels and aerosols). They also don’t require you to put your medically necessary liquids into a liquids bag.

However, they do have some limitations on liquid medication.

They require you to only bring “reasonable quantities” and state that the liquids rule exemption only allows certain items to be carried on the aircraft when the item is declared and it is:

Required during your flight and/or at your travel destination;
Not available at the airport in the sterile area (after the screening checkpoint) and/or;
Not available at your travel destination.

Reasonable quantities for your trip

When you are bringing your liquid medications through security the TSA 3-1-1 rule does not apply. Instead, TSA will allow you to bring in “reasonable quantities for you trip.” This is a subjective definition so there is going to be room for agent discretion.

Therefore, try not to go too far with your liquid medications if you think that you might be bringing in an unreasonable amount. It is a very good idea to have a clear stated purpose for why you need that quantity of liquid medication. And it might even be a better idea if you have a signed doctor’s note explaining why you need that much medication.

It could probably help your cause if you can explain your dosage requirements in relation to the quantity of medication you are bringing. For example, if you require 10g of medication per day and you are bringing 100g with you on a ten day trip, that makes total sense.

But if you require 10g of the medication per day and you are bringing 3,000g with you for a weekend trip that could be a different story….

At some point TSA added more clarity to this rule when they stated that the medication would need to not be available at the airport in the sterile area (after the screening checkpoint) and/or not available at your travel destination.

I don’t really like this rule because essentially a TSA agent could force you to throw out a large bottle of NyQuil just because it would be available at an outrageous price within the airport. Also, sometimes it’s difficult to know whether or not something will be available at your destination so it is just smart thinking to bring it with you. Nevertheless, those are the rules.

Notify the agents

TSA also states that you should notify the TSA agent about your liquid medication before you go through security screening.

Personally, I have flown with liquid medication many times before and have never notified TSA about it nor have they given me any push back (there’s a prescription on the medication bottle).

Even though that is how I have done it in the past, I would recommend disclosing your medication just to make things easier. This is especially the case if you’re traveling with accessories associated with your liquid medication such as freezer packs, IV bags, pumps, and syringes.

If TSA does notice your liquids or you tell them about them, the medically required liquids will be subjected to additional screening that could include being asked to open the container. They might pour the substance into another container, test out a small sample of the medication, or swab it for explosives.

So just be prepared to pop the top if you are asked to.

Note: You will not have to put your liquid medications into a Ziploc bag.

Liquid medication bottles — **Medically required liquids** are not subject to the TSA 3-1-1 Rule.

How to pack medication for a flight in a carry-on or checked bag

TSA will allow you to bring your medication onto a plane via carry-on or checked baggage.

Obviously, you will not have access to your checked baggage when you are flying in the plane so if you are in doubt about whether or not you might need access to your medication, then I highly recommend that you pack it in your carry-on.

Plus, remember if your checked bag containing your meds gets lost your medication is also lost.

If you bring your medication as a carry-on you should not be required to show or declare that you are bringing medication, unless you are bringing liquid medication or certain other types of medical instruments like syringes.

(Some travelers inform the TSA agents about all medications they are bringing but that does not always seem to be required in my experience.)

When packing pills or medication I would try to keep them organized in a clear plastic bag just to make things easy at all times.

Try to pack that bag in an easily accessible area within your carry-on so that you can quickly retrieve it if you need to declare or allow inspection for any of your medications.

Also, it’s a good idea for your medications to be labeled to facilitate the security process. (Labeling your meds is not required but it is recommended by TSA.)

When packed in a carry-on and going through a security checkpoint your medication can undergo a visual or X-ray screening (you can choose).

Does TSA require pills to be in a prescription bottle?

Believe it or not TSA does not require your pills to be in a prescription bottle or to show them a copy of your prescription. The catch is that states have different laws regarding how you can legally travel with prescription items.

Some states might require you to carry your pills and a bottle with a prescription and therefore it is always a good idea to keep your pills in a bottle with a prescription label if possible or at least keep the prescription with you if you are using a pill container/organizer.

Also, many countries have very strict rules on prescription medication so be sure to keep up with the latest laws before departing the country. Some might require you to submit a letter from a physician and some countries such as those in the Middle East have very strict laws regarding bringing in certain types of medications.

It is not very difficult to find stories about US tourists getting locked up abroad in prison for bringing medications through the airport. Read more about traveling internationally with medication here.

One interesting thing about prescriptions is that if you forget your ID you can actually use your prescription labels to help verify your identity.

Tip: Ask your pharmacist for extra containers with your name and the medication information on them if you want to carry smaller amounts of drugs with you.

It’s always a good idea to have your prescription on you.

What are the TSA rules for flying on a plane with injectable medication?

You are allowed to travel with injectable medication on a plane. You may also bring unused syringes when they are accompanied by injectable medication. You must declare these items to security officers at the checkpoint for inspection. TSA also recommends, but does not require, that your medications be labeled so it’s a good idea to go with their recommendation.

What if I need to keep my medication refrigerated when flying?

If you need to keep your medication refrigerated you can use “ice packs, freezer packs, gel packs, and other accessories” to keep your medication cool. You will need to present these at the screening checkpoint in a frozen or partially-frozen state.

It would be a good idea to do a “test run” to see how long your packs can stay refrigerated, especially if you are going to be dealing with a long layover or flight. Some airplanes may have refrigeration but I would not count on that.

Does TSA allow over the counter medication on a plane?

TSA will allow you to bring over the counter medication on a plane, which means you’ll be fine to bring along things like: Tylenol, Advil, Aleve, ibuprofen, etc. Just remember that the rules pertaining to liquids will apply to OTC drugs unless they are medically necessary.

I always advise people to put their medication in a clear plastic bag just to make things easier when making your way through airport security.

What about flying with other items?

If you have questions about bringing other types of items through TSA airport security screening (like food or alcohol), make sure to check out the articles below:

FAQ

Can you take prescription medication on a plane?

Yes, prescription medication is allowed on planes.

Does my medication have to be in original bottles when flying?

No, your medication does not have to be in the original bottle. However, it’s usually a good idea to have a prescription on hand just in case you’re questioned about the medication.

Can you “sneak” pills on airplane?

It’s best to be upfront about bringing medication through TSA, especially because TSA is pretty flexible about what medications you can bring through and all medication must be screened. If you are trying to sneak illegal drugs through TSA security you could be referred to law enforcement.

Can I take a pill organizer on a plane?

Yes, you can bring your pill organizer on a plane with your pills inside.

Can I bring someone else’s prescription on a plane?

TSA does not require you to show your prescription so it could be possible to bring someone else’s prescription meds with you on a plane. However, it’s a good idea to make sure you are complying with state laws regarding prescription drugs when traveling. In some cases, it may be illegal to possess controlled substances prescribed to someone else.

Can you fly with cough syrup?

Yes, cough syrup will be considered a liquid so you should “declare” it when going through TSA, especially if it is above 3.4 ounces.

Can you bring testosterone gel on a plane?

Yes, you can bring testosterone gel on a plane. While you may not need your prescription it never hurts to bring it along.

Can I bring needles (syringes) on a plane?

TSA states used syringes are allowed when transported in Sharps disposal container or other similar hard-surface container. Unused syringes are allowed when accompanied by injectable medication. You must declare these items to security officers at the checkpoint for inspection.

Final word

As you can probably tell, TSA rules regarding medication are actually pretty lenient. They allow you to bring an unlimited amount of pills and solid drugs and they don’t even require you to show or disclose that you are bringing those drugs through the airport and onto the plane.

They also will allow you to go above the liquids rule if you are willing to allow them to inspect your drugs if necessary. And they don’t even require you to show your prescription for drugs. Therefore if you are planning to travel through the airport with your medication you may not have as difficult a time as you may have imagined.

Known Traveler Number Guide: (How to Lookup, Global Entry, Pre-Check) [2023]

This comprehensive article will tell you everything you need to know about your Known Traveler Number.

I’ll cover how you can get one and the best way to do that with programs like TSA Pre-Check and Global Entry. I’ll show you how to look-up your Known Traveler Number and add it to your travel itineraries with airlines like United, Southwest, and Delta.

Finally, I’ll explain the differences between a Known Traveler Number and a Redress Number.

What is a Known Traveler Number?

A Known Traveler Number, also called your “KTN,” is a 9-digit number used to link your TSA Pre-Check enrollment to your travel itinerary in order to ensure that you can receive TSA Pre-Check benefits like expedited security screening.

This is the same number used for other trusted traveler programs, such as Global Entry, NEXUS, and SENTRI. However, for these latter programs, this number is known as your “PASSID.”

Tip: Use the free app WalletFlo to help you travel the world for free by finding the best travel credit cards and promotions!

TSA pre-check station — Your Known Traveler Number is vital for getting expedited security screening with TSA Pre-Check.

Why do you want a Known Traveler Number?

With a Known Traveler Number, you can participate in TSA Pre-Check, which means you’ll be able to breeze through security at airports.

How do you get a Known Traveler Number?

You can get a Known Traveler Number by signing up, getting approved, and paying the fees for any of the following programs:

TSA Pre-Check

As already discussed, TSA Pre-Check will usually get you through airport security in a breeze.

You’ll usually get access to a priority security line which is often much shorter than the standard security line (though not always, unfortunately).

You’ll also be able to go through a less restrictive and invasive screening process. You often only have to pass through a traditional metal detector (as opposed to the full-body scanners) and you also get to enjoy the following benefits:

Shoes can stay on
Belt can stay on
Light jackets can stay on
Laptops allowed to stay in bag
Liquids (3-1-1 Rule) can stay in bag

This program costs $78 to enroll for five years and it does not require the extensive interview process that Global Entry requires. There are multiple ways to get TSA Pre-Check for free and you can read about those here.

Global Entry

Global Entry would be my preferred method for obtaining a Known Traveler Number. That’s because not only will you get TSA Pre-Check, but you’ll also get expedited entry at Customs and Immigration when making your way back into the US.

This program does require you to attend an interview to be approved but the interview process is not difficult at all. If you’ve got a clean criminal history and come prepared with your documents then you should pass the background check and interview without any issues at all.

In some cases this “interview” process will only take about five minutes total.

You might get asked some very basic questions like what countries you have visited and whether or not you have traveled for business or pleasure. It’s hardly anything close to an interrogation in most cases.

The hardest part is often scheduling the interview because availability can be limited and in some cases it might take weeks (or even months) to find an open slot.

Luckily, some airports offer interviews upon arriving from international locations. So if you have some international travel coming up, this can be one of the easiest ways to get approved for Global Entry.

There are many credit cards that come with a $100 statement credit for your Global Entry application fee, so it’s very easy to get this program for free. My personal recommendations for getting a $100 statement credit for your Global Entry/TSA Pre-Check is to go with the United Explorer Card. It has great perks and a low annual fee and you can read more about it here!

Since you’ll get both TSA Pre-Check and expedited entry back into the US, I think Global Entry is the way to go for many people.

NEXUS

NEXUS is a joint program between the US and Canada that will grant pre-approved, low-risk travelers expedited entry into both Canada and the US. Specifically, membership in the NEXUS program allows you to reduce your wait times at designated ports of entry by:

Using dedicated processing lanes at land border crossings
Using NEXUS kiosks when entering Canada
Using their card in dedicated SENTRI lanes along the U.S.-Mexico border
Using Global Entry kioks when entering the United States, and
Calling a marine telephone reporting center to report your arrival into the United States and Canada

You may also be granted access to the Canadian Air Transport Security Authority (CATSA) Security Line at some Canadian airports to expedite airport pre-boarding security screening. (This is like a Canadian version of TSA Pre-Check.)

Just like Global Entry, NEXUS will require you to clear a background check. The difference is that this background check also is submitted to Canadian authorities, such as the Canadian Security Intelligence Service (CSIS), Royal Canadian Mounted Police (RCMP).

One of the major draws to the NEXUS program is that the application fee is only $50. This is surprising since NEXUS comes with both Global Entry and TSA Pre-Check, which cost $100 and $85 respectively. For people who live near or travel between the US/Canada border, NEXUS is an especially attractive bargain.

SENTRI

The Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.

You can enter the United States by using dedicated primary lanes into the United States at Southern land border ports so this is a program you might be interested in if you’re traveling between the US and Mexico a lot.

You might be a little overwhelmed with all of the different Trusted Traveler programs and perhaps you’re not sure which program you should sign-up for.

If that’s the case you can check out this TSA tool which can help you narrow down what program is most ideal for you based on your citizenship, number of flights, and travel destinations.

CLEAR

CLEAR is a privately owned service offered to passengers that allows them to bypass the lines going into airport security, whether you are going into the standard security line or the TSA Pre-Check line.

In order to use it you find the CLEAR line leading to security which should have little to no line and then you simply scan your boarding pass and biometric data and then you’re off to the races and able to skip whatever line you would have been waiting on. You don’t even have to show your ID.

CLEAR can be great for frequent flyers in busy airports but it’s not cheap at $179 per year (though cheaper promos are often available). This program does not require you to have a Known Traveler Number.

Mobile Passport

Launched in the fall of 2014, Mobile Passport Control is an app, developed by Airside Mobile and Airports Council International-North America in partnerships with CBP, that you can download to use in order to expedite your entry into the US. It’s available in the Apple App Store and Google Play.

It’s free to use and can be just about as good as Global Entry at some airports, though I’d still take Global Entry over Mobile Passport.

That’s because Global Entry gets you Pre-Check and also allows you to get through customs AND immigration while Mobile Passport often only get your priority access through immigration. This program also does not require you to have a Known Traveler Number.

Adding a Known Traveler Number

Once you have your Known Traveler Number, you’re going to need to add that number to your travel profiles for the various airlines so that your Known Traveler Number will automatically show up in your itineraries.

However, you should note that your Known Traveler Number will NOT automatically show up in all of your travel itineraries.

Many people assume that once they add their Known Traveler Number to their profile, it will always show up but that’s not the case. So you always need to double check that your KTN was added.

Below, you can see how to add your Known Traveler Number to some of the major airlines. For whatever reason, it is not always the easiest thing to do since you often have to click around a lot.

Usually you can find where to input it if you just look for your profile and a button allowing you to edit your profile, but the steps below should help you locate this.

American Airlines

Sign in to your American Airlines account and then click on your name at the top of the page. Then click on “your account.” Next, click on “edit account” and then click on “Information and password.” Scroll down and then under “Secure traveler,” you will see where to input your Known Traveler Number.

Southwest

Sign in and click on “My Account” and then scroll to “My Preferences” to change your personal details within your profile information.

United

Sign in and click on Profile and Preferences and then click on “Travel identification documents” and then you’ll see the area to enter it in below.

Delta

Go to the Delta website and log-in and then proceed to My Delta -> My Profile -> Basic Info. You’ll then see a field where you can input your Known Traveler Number.

JetBlue

First, sign in to your JetBlue account. Click on the arrow in the upper right corner by your name and then click on “Edit profile.” Scroll down and you will see where to input your information.

Hawaiian Airlines

First, sign in to your Hawaiian Airlines account. Go to My Account and under that click on “Profile & Settings.” Click on the travel tab and you will see where to input your information.

Travel portals and OTAs

Most online travel agencies (like Expedia) will allow you to enter in your Known Traveler Number into your profile which should populate into your itinerary when you make a booking.

But since you’re dealing with a third party, you should always verify that your number was properly included in your booking.

Add Known Traveler Number after booking?

If you add your Known Traveler Number to your profile after you make a flight reservation, there’s a good chance that your flight itinerary is not linked to your Known Traveler Number and you won’t get TSA Pre-Check.

In that case, you should be able to call up the airline and request for them to input your number into your itinerary.

You could also just wait until you arrive at the check-in desk for baggage and request for your Known Traveler Number to be added to your boarding pass.

Also, sometimes you’ll have to re-add your Known Traveler Number to specific itineraries. It’s not always clear why this happens but sometimes you’ll just have to do it.

If you ever are given a boarding pass without TSA Pre-Check on it and you know you have a TSA Pre-Check membership, simply approach an agent at the check-in desk and tell them you would like to add your Known Traveler Number.

It’s usually no problem for them to do this and they can re-issue you a boarding pass in a couple of seconds that has TSA Pre-Check.

For the reasons above, I highly recommend that you keep your Known Traveler Number somewhere easily retrievable like in your smart phone in a folder or app that you won’t forget about and can quickly pull up.

Where can I look up and find my Known Traveler Number?

If you are a member of the TSA Pre-Check Application Program you can, look up your KTN online.

If you are a member of another trusted traveler program, such as Global Entry, NEXUS, or SENTRI, log on to the Trusted Traveler Program website to obtain your PASSID, which once again is the same as your KTN.

You’ll find it right under “Program Memberships.”

You can also check the back of your trusted traveler cards for your PASSID. Note that TSA does not issue an ID card like Global Entry, NEXUS, and SENTRI do.

What is a redress number?

You might also be wondering about a redress number since that field often shows up near where you input your Known Traveler Number.

A redress number is the record identifier for people who apply for redress through the DHS Travel Redress Inquiry Program (DHS TRIP).

“DHS TRIP is for travelers who have been repeatedly identified for additional screening and who want to file an inquiry to have erroneous information corrected in DHS systems.”

For example, someone might share the same name as another person on a no-fly list and that might bring up a red flag every single time this unfortunate traveler attempts to board a plane.

The redress number will help those people avoid additional searches, pat downs, and questioning in the future.

So in case you were wondering a redress number really has nothing to do with your Known Traveler Number.

Known Traveler Number for Military members

If you are a member of the military, you can utilize TSA Pre-Check for free.

Members of the U.S. Armed Forces can get expedited screening including those serving in the U.S. Coast Guard, Reserves, and National Guard.

This can be done by using the official Department of Defense (DoD) identification number when making flight reservations. Your 10-digit DoD ID number is located on the back of your Combined Access Card ID and it is not the same as your SSN. Read more about how to utilize this benefit here.

TSA Pre-Check vs Global Entry

Now that you’re aware of all of the benefits you might be wondering whether or not you should choose TSA Pre-Check or Global Entry.

The answer to this question depends a lot on your personal preferences.

If you are only going to be traveling within the US then your need for Global Entry will be nearly zero.

In that case, getting TSA Pre-Check should be just fine. The only drawback to that is that if an unexpected trip comes up you’ll lose out on the benefit you could have had with Global Entry.

On the other hand, if you’re going to be traveling internationally then you might want to think about Global Entry since it will save you a lot of time getting back into the country.

The two drawbacks to Global Entry are that it requires you to attend an interview and that the background check can be tough to clear if you have anything on your record like a DWI, DUI, etc.

Known Traveler Number FAQ

What is the easiest way to get a Known Traveler Number?

The easiest way would be to get approved for TSA Pre-Check.

Do I need a Known Traveler Number for CLEAR?

No, you do not need a Known Traveler Number for CLEAR?

How do I add my Known Traveler Number to my itinerary?

At the time of booking, you will typically see a field where you can enter your Known Traveler Number. In addition, you can add your Known Traveler Number to your frequent flyer profile.

If you are at the airport, you can also ask an agent to add your Known Traveler Number to your boarding pass.

What is the difference between a Known Traveler Number and PASS ID?

There is no practical difference and these are essentially the same.

Final word

As you can see, getting a Known Traveler Number can be very easy and can even be done for free with the right credit card.

I recommend going with a program like Global Entry to get your PASSID/Known Traveler Number and using a credit card with a $100 credit for Global Entry.

If you always keep your Known Traveler Number with you at all times you’ll be able to add it to your boarding pass when needed and there shouldn’t be any major issues.

Can You Bring Alcohol & Mini-Liquor Bottles on Planes: A Sobering TSA Guide [2023]

Sometimes a little bit of alcohol goes a long way when it comes to relaxing on a plane.

Yes, most airlines sell alcohol to passengers but what about the much cheaper and convenient route of bringing your own hooch through TSA?

Is it actually legal to take your own alcohol on board or are you asking for trouble with the FAA.

I was curious about this myself and so I took a deep dive into the FAA/TSA rules and even spoke with some TSA agents to see exactly what was allowed and what wasn’t.

In this article, I will talk about the rules for bringing alcohol and mini-liquor bottles through the airport and drinking them on the plane.

Can you bring alcohol on a plane?

Yes, you can bring alcohol on a plane but there are very specific restrictions that differ based on whether you are bringing your alcohol on in your carry-on or in your checked baggage.

If bringing alcohol in your carry-on, you need to abide by the TSA liquids rule and the FAA regulations on alcoholic content and consuming alcohol on the plane.

And if you’re bringing alcohol in your checked baggage, you need to be mindful about the FAA regulations on alcoholic content and limits to the total quantity allowed, especially when coming back from an international trip.

Below, I’ll break down these buzz-kill restrictions into clear terms so that you don’t miss out.

Bringing alcohol on a plane as a carry-on

If you want to take your booze with you in your carry-on, you’ll have to contend with the TSA liquids rule and a couple of very important FAA regulations.

Alcohol and the TSA Liquids 3-1-1 Rule

Alcohol fall in the liquids category and so when you are bringing it on as a carry-on you always have to abide by this rule.

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

(When going through the checkpoint, you’ll have to remove your quart-size bag from your luggage unless you have TSA Pre-Check.)

So if you plan on bringing alcohol in your carry-on bag, this rule means you’ll be limited to only small amounts.

Alcohol and FAA regulations

If you like guzzling down some seriously strong alcohol I’ve got some bad news for you.

The FAA forbids you to bring beverages with an alcoholic content of more than 70% (more than 140 proof) in your carry-on or checked baggage.

Why is that? It’s just a little bit too flammable for comfort.

The next regulation you need to be aware of pertains to partaking in your adult beverages on the plane.

FAA regulation §135.121 on alcoholic beverages states that:

No person may drink any alcoholic beverage aboard an aircraft unless a certificate holder operating the aircraft has served that beverage.

Notice that the regulation only states that you may not drink alcohol unless a “certificate holder operating the aircraft” (aka a flight attendant) has served it to you.

This means that in theory you could request a flight attendant to serve you your own alcohol and be compliant with the FAA regulation.

But don’t get too excited.

First, to pull this off you need some serious master of persuasion skills. This is especially true in the post-pandemic world.

More crucial, if you look at the policy stated by virtually every major US airline you will see that they don’t seem very open to this idea (or they are just outright against it).

Airline	Link	Notes
Alaska Airlines	Policy	“may not be consumed… unless it has been provided by a flight attendant”
American Airlines	Policy	“Opened containers aren’t allowed”
Delta Air Lines	Policy	“must be in its original unopened retail packaging”
Fronter	Policy	“Personal Alcoholic Beverages may not be consumed onboard the aircraft”
Hawaiian	Policy	“may not be consumed… unless served by a Hawaiian Airlines flight attendant.”
JetBlue	Policy	“You are not allowed to consume your own alcohol while on board”
United Airlines	Policy	“You can’t drink the alcohol you bring on our aircraft”

“One does not simply drink their own alcohol on a plane”

So generally speaking, drinking your own alcohol on a plane is going to be difficult to do (the legal way).

But what would you be risking if you chose to violate the law?

The FAA could slap a fine on you. In fact, they have been busy dropping huge fines on unruly passengers for alcohol related incidents.

In reality, if you were asked to put away your alcohol and you immediately complied I doubt you would suffer any consequences.

It’s only when things escalate that the fines seem to come into play.

Mini liquor bottles

Although the odds might be stacked against you when it comes to consuming your alcohol on the plane, you should at least know that bringing mini liquor bottles on the plane is permitted.

Subject to a couple of restrictions, of course.

First, going back to the liquids rule.

Mini liquor bottles are about 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid.

If you would like to bring more alcohol, you can consider pouring your liquor bottles into larger carry-on size containers that are 3.4 ounces.

The tricky thing to remember is that the percent of alcohol can dictate what you can bring in your 3.4 ounce containers.

TSA has no rules against transporting alcohol in bottles that you did not purchase the alcohol in but if they contain more than 24% alcohol but not more than 70% alcohol they need to be in unopened retail packaging.

So that means that many types of vodka, gin, rum, whiskey, tequilas, and other alcohols cannot be legally transferred from an open bottle of liquor into one of your personal liquid bottles and then carried onto a plane because the alcohol would not be in unopened retail packaging.

For your reference, here are some ranges for the alcoholic content of some common beverages:

Alcohol Percentage Content

Vodka | ABV: 40-95%
Gin | ABV: 36-50%
Rum | ABV: 36-50%
Whiskey | ABV: 36-50%
Tequila | ABV: 50-51%
Liqueurs | ABV: 15%
Fortified Wine | ABV: 16-24%
Unfortified Wine | ABV: 14-16%
Beer | ABV: 4-8%
Malt Beverage | ABV: 15%

How many mini-liquor bottles can you fit in a quart sized Ziploc bag?

The amount of bottles that you can fit inside of a quart size bag will depend on the shape and size of the mini-liquor bottles.

However you can generally expect to fit between five and seven mini-liquor bottles inside a quart size bag.

Just remember that the bottles must fit “comfortably” within the bag.

Comfortably means that the bag will seal without busting at the seams.

If you cannot completely seal up that bag then the TSA agent will likely state that you have not met the “comfortable” requirement and you will have to throw away some of your alcohol.

Making cocktails on planes

You might be surprised that there are some food items great for cocktails that you can bring on planes. For example, you can bring fresh fruits (lime, lemon, etc.) with you through airport security.

Most airlines will serve many drinks that are perfect for mixing up cocktails such as, orange juice, Coke, Sprite, ginger ale, tomato juice, and other fruit juices. These are usually served either on a complementary basis or for a small fee.

If you want some inspiration for cocktail ideas you find those here.

You can also buy cocktail kits online.

The key here is to be mindful about those FAA regulations.

What about duty-free liquor bottles?

If you have purchased liquor bottles from a duty-free store then you should be able to bring those on the plane even if they are larger than the standard 3.4 ounces allowed.

If you are coming in from an international flight and you are connecting to another flight within the US, you should still be able to bring your duty-free liquor bottles with you through TSA and onto your connecting flight.

However, there are special requirements for doing so.

You may carry duty free liquids in secure, tamper–evident bags, more than 3.4 oz or 100 ml in your carry-on bag if:

The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
The original receipt for the liquids is present and the purchase was made within 48 hours.

Read more about this rule here.

Alcohol and checked bags: know your limits

If you want to bring your booze in your checked baggage, there are additional (but similar) restrictions that apply in that case.

Let’s start with the lightest type of alcohol.

Alcoholic beverages with 24% alcohol or less are not subject to limitations in checked bags.

This would be mostly things like beer, champagne, wine, and some limited liquors.

Alcoholic beverages with more than 24% but not more than 70% alcohol are limited in checked bags to 5 liters (1.3 gallons) per passenger and must be in unopened retail packaging.

And, as stated above, beverages with more than 70% alcohol are not allowed on the plane at all.

The rules above don’t mean you should bring in unlimited amounts of alcohol, though (especially if flying into the US).

The CBP states that:

There is no federal limit on the amount of alcohol a traveler may import into the U.S. for personal use, however, large quantities might raise the suspicion that the importation is for commercial purposes, and a CBP officer could require the importer to obtain an Alcohol and Tobacco Tax and Trade Bureau (TTB) import license (which is required for all commercial importations) before releasing it.

So if you go pushing things to the limit you could find yourself subjected to license requirements. And I’m going to go out on a limb and guess that those licenses aren’t free.

So what would be a safe limit when bringing alcohol back into the country?

CBP does provide us with some guidance and they state:

A general rule of thumb is that 1 case of alcohol is a personal use quantity – although travelers are still subject to state restrictions which may allow less.

So if you are bringing in alcohol in your checked baggage, my advice would be to stick to one case of alcohol. If you try to push the limits, you could be subject to additional fees or worse, so it is just not worth it in my opinion.

Alcohol on planes FAQ

Is it illegal to bring alcohol on the plane?

Contrary to what you might believe, it is not illegal to bring your own personal alcohol on a plane.

Can you drink your own alcohol on a plane?

The FAA requires all alcohol consumed on a plane to be served by a flight attendant. Most airlines have policies that don’t allow you to drink your own alcohol on the plane so the odds of you getting a flight attendant to serve you your own alcohol are probably very low.

Can you bring syrups for cocktails?

Many cocktail recipes call for special syrups. If you are wondering about bringing syrups on the plane, you should know that TSA will consider them to be liquids and they will be subject to the 3-1-1 rule. You can read more about different foods and liquids permitted to bring on a plane here.

Can you take mini-liquor bottles through airports?

Yes, you can take mini-liquor bottles through airports and onto planes. However, you need to be aware of the special regulations that govern liquids through security and those for serving alcohol on planes so that you are not violating any laws.

How old do you need to be to drink alcohol on a plane?

You must be age 21 to consume alcoholic beverages on a US plane.

Final word

You can bring a handful of your mini-liquor bottles through airport security and even drink them on the plane.

However, you need to be aware of the FAA regulations and decide the best way for you to go about complying with those. Some airline crews may be more relaxed than others or be more strict so you will have to get a sense of how the flight crew is going to be.

TSA Rules for Bringing Lighters on Planes: Don’t Get Torched! [2023]

When it comes to anything that can create an explosion or open flame, you always want to be very careful about bringing that type of item on a plane. Because lighters by their very nature fall into this category, it’s a good idea to get up to speed on the FAA/TSA requirements for flying with them.

In this article, I will break down all of the TSA rules regarding taking lighters through airport security and bringing them on an airplane.

What are the TSA rules for bringing lighters on planes?

According to the FAA, when traveling on a commercial airline you can bring one lighter that uses a flammable gas (butane) or that uses a flammable liquid that is absorbed in a lining (Zippo-type of lighter).

You are allowed to bring disposable and Zippo lighters without fuel in carry-on bags or checked bags but there must be no traces of fuel or vapor inside the lighters.

(The FAA recommends that passengers pack empty lighters in checked baggage accompanied by a note explaining that they contain no fuel.)

Lighters that contain fuel are prohibited in checked bags unless they comply with the Department of Transportation exemption (more on that below).

FAA building — The FAA has a strong say in the policy for lighters on aircraft.

Bringing a lighter through airport security

When bringing your lighter through airport security, you must bring the lighter in your carry-on or on your person.

I’d recommend placing the lighter in a place that is easily retrievable and not stuffed in the bottom of your carry-on bag just in case you need to remove it.

You also don’t want to risk it getting busted or leaking.

Also, while you can bring empty lighters in your carry-on I would put them in your checked baggage to avoid getting slowed down through security. This is especially true if you have many empty lighters.

You can also bring your lighter “on your person.”

On your person just means that if the lighter is not in your bag, it needs to be in your pocket.

But when you go through security screening, you’ll most likely need to drop your lighter in one of the bins. After that, there should be no issue with storing the lighter in your pocket.

Note: If a carry-on bag is checked at the gate or at planeside, any lighter in the carry-on must be removed from the bag and kept with the passenger in the aircraft cabin.

Different types of lighters

The Homeland Security Department has made moves to ban lighters in airports in the past.

But for now, you are permitted to bring in various types of lighters so long as you comply with the restrictions mentioned above and below.

One quick tip I will offer.

Lighters are pretty cheap so sometimes it’s just a lot easier to purchase them at your destination rather than risk dealing with a TSA agent who may not be well-versed in the rules.

Disposable and Zippo lighters

The most common types of lighters are the disposable cigarette lighters (e.g., BIC lighters) and the Zippo lighters.

If you are planning on bringing a lighter through airport security your best bet is to bring something like this because airport security will be familiar with them and you should not run into issues.

Note that the FAA states only one lighter is allowed but TSA is silent on the issue on their website.

Just keep in mind that anytime you are bringing an item that is subject to regulations, you might get pulled aside and your item/bags might be serviced extra thoroughly.

Typically, this additional screening is pretty quick but in some rare cases it can drag out.

lighter with flame — Disposable lighters like this one are allowed on planes.

Arc Lighters, Plasma Lighters, Electronic Lighters, E-Lighters

TSA prohibits arc lighters, plasma lighters, electronic lighters and eLighters in checked baggage.

These are those modern/fancy looking lighters that often have USB charging capabilities. While they look pretty gnarly, these are not allowed to be brought on as a checked item.

If bringing these as a carry-on, TSA states: “Measures must be taken to prevent unintentional activation of the heating element while on board the aircraft.”

In other words, you may have to remove the battery from the lighter or place the lighter into a protective case.

In addition, be aware that each lithium ion battery must not exceed a Wh rating of 100 Wh (or for lithium metal batteries, a lithium content of 2 grams).

TSA will not allow you to charge these devices or the batteries on the aircraft.

Gun lighters

Gun lighters can be highly problematic in an airport for a couple of reasons.

For one, some of these look like realistic firearms and bringing firearms through an airport has specific regulations that you have to comply with so that you don’t face stiff penalties.

Second, these are larger lighters that are prohibited in both carry on and checked baggage.

Bottom line: avoid bringing any lighter that looks like a gun or any other type of weapon (e.g., grenades).

Lithium battery powered lighters

Lithium battery powered lighters are lighters that depend on lithium batteries which are one of them many prohibited items for checked baggage.

However, lithium batteries can be brought on the plane as a carry-on so lithium battery powered lighters are allowed. See the restrictions above.

Torch lighters

According to the TSA, torch lighters create a very thin, needle like flame that is a higher temperature and more intense than the flame from a traditional lighter. In fact, the temperature from these lighters can reach up to 2,500°F.

These ultra-hot lighters are often used for pipes and cigars and they maintain a consistent stream of air propelled fire regardless of the angle at which they are held.

Different types of torch lighters include jet lighters, blue-flame lighters, and cigar lighters. Other types of torch lighters include chef torches, micro torches, and utility torches.

Torch lighters are not allowed as a carry-on item or as a checked bag item.

Lighter fluid

As most of you are probably aware, lighter fluid is highly flammable and is not allowed as a carry-on or a checked bag item.

Matches & candles

If you are curious about matches, know that one book of safety (non-strike anywhere) matches are permitted as carry-on items, but all matches are prohibited in checked baggage.

The FAA mentions that “airline passengers may bring only one lighter or one book of matches into the aircraft cabin,” so you may have to choose between your lighter or your matches.

Also, here’s an overview of bringing candles on a plane.

Department of Transportation exemption for lighters

The Department of Transportation (DOT) exemption allows you to bring up to two of your disposable/Zippo lighters in checked baggage if they are properly enclosed in a DOT approved case.

These are airtight travel containers that reduce the risk involved with transporting lighters. Typically, they only hold one lighter but some hold two.

Some popular manufacturers have secured DOT permits for their lighter travel containers and these include manufacturers like: Colibri, Prometheus, and Zippo.

You can try to find these at specialty stores but you can also purchase them online.

Keep in mind that these special containers are the only way that you can carry lighters in checked baggage (unless the lighter contains no fuel).

Note: When shopping for a travel container for your lighter, make sure the container is marked with the DOT special permit number.

Shipping

You might be thinking that you can just get around the TSA guidelines by shipping your items in the mail.

Unfortunately, it is against the law to ship lighters containing fuel or fuel residue. Lighter fluid and butane refills are also forbidden in the mail.

Once again, remember how cheap lighters can be and consider just purchasing them at your destination.

Vapes and e-cigarette’s

You might also be curious about transporting vapes and e-cigarettes through airport security and on planes. The rules for these varies and depends on the exact set up of your vape, so be sure to check out TSA Rules for Vapes and e-Cigarettes.

TSA Rules for lighters FAQ

Can you bring a torch lighter on a plane?

No, you cannot bring a torch lighter on a plane as a carry-on or in a checked bag.

What type of lighters are allowed on a plane?

You can bring Zippo lighters, disposable lighters, and lighters with lithium ion batteries on as a carry-on.

Can I bring lighters in my checked baggage?

You can bring up to two Zippo/disposable lighters in your checked baggage but only if you have stored in a DOT approved travel case.

How many lighters can I bring in my carry-on through TSA?

The FAA states only one lighter is allowed in your carry-on.

Can I bring empty lighters on a plane?

Empty lighters are not regulated and thus you are allowed to bring them in your carry-on or checked bag. It’s recommended that you place these in your checked bag with a note declaring that the lighters are 100% empty.

Final word

As you can see, there are a lot of special rules for bringing lighters on airplanes. If you stick with just bringing one basic disposable lighter through airport security on your carry-on or on your person, you should not run into any issues.

But if you are trying to bring in more than that or are interested in transporting other types of lighters, you will start to run into trouble. So my advice would be to try to keep things as simple as possible when it comes to bringing along a lighter.

Can You Bring Knives on a Plane? TSA’s Rules [2023]

Are you wondering whether or not you can bring knives through TSA security and on to a plane?

The answer isn’t so clear to a lot of people due to past policies that were implemented and then later reversed.

But in this article, I’ll tell you everything you need to know about bringing knives through airport security and on board your plane.

I’ll cover the TSA rules for both carry-ons and checked baggage and also talk about some other sharp objects.

Can you bring knives on a plane?

You cannot bring any knives in your carry-on or personal item, except for “plastic or round-bladed butter knives.” However, many types of knives are allowed in your checked baggage.

While TSA may allow you to transport various knives in your checked baggage keep in mind that many states and countries outlaw certain types of knives so traveling with them could still be illegal.

Keep reading below for more details on the TSA rules for knives.

The 2013 “changes” on knives

You might be a little bit confused about the ban on small knives since at one point it looked like TSA was going to allow those knives on board. In 2013, TSA decided to allow small pocket knives to be brought aboard aircraft.

There were certain size regulations, such as requiring the blades to be no longer than 2.36 inches long and no wider than 1/2 inch. The knives also could not have certain features such as a molded grip or a locked or fixed blade.

An example of the old TSA knives regulations. **These rules do NOT apply today since all knives are prohibited.**

Why on Earth would they think this was a good idea?

Well, according to the TSA they believed that doing so would allow the airport screeners extra time so that they could focus on finding more dangerous objects like bombs, IEDs, etc. They also stated that due to reinforced cockpit doors, small knives were not a major threat to hijackings.

But after TSA announced this, there was major pushback from the airlines, unions, and government officials. Many flight attendants didn’t feel safe knowing that passengers could be equipped with knives (even if they were very small knives).

Three days before the new changes were to go into effect, TSA decided to do more consulting regarding the changes and they eventually scrapped the changes altogether.

So to this day even small knives such as pocket knives are not allowed on a plane. And unfortunately, many people do not get that memo so pocket knives remain one of the most confiscated items by TSA.

You might also be interested in reading about bringing firearms through security.

Bringing knives in your carry-on

Knives in your carry-on are never allowed, except for “plastic or round-bladed butter knives.”

Round-bladed means that they are not serrated, as some butter knives do have grooves and ridges along the blade.

Besides these exceptions, there are no “TSA Approved” knives that you can bring on to a plane in your carry-on. This would include lightweight knives, non-locking knives, and compact knives.

Remember that in general, you are prohibited from traveling with any sharp objects in your carry-on baggage

The penalties for bringing a knife in your carry-on can be quite stiff.

For example, according to TSA, you could get hit with up to a $2,050 fine if you’re caught with some knives in your carry-on since they could fall in the banned category below:

Axes and hatchets; bows and/or arrows; ice axes and ice picks; knives with blades that open automatically (such as switchblades); knives with blades that open via gravity (such as butterfly knives); any double-edge knives or daggers; meat cleavers; sabers; swords; machetes; throwing stars

There are countless stories out there of TSA confiscating knives and other sharp objects so they will not hesitate to take these items if they are discovered in the x-ray machine.

If you want to find out more about how TSA fines passengers when they bring dangerous items through security be sure to read our complete guide here.

One more thing to consider about going through security checkpoints with your knives.

“TSA officers have the discretion to prohibit any item through the screening checkpoint if they believe it poses a security threat.”

This means that even if an item is not prohibited and is allowed, an agent could still see it as a threat and not allow it to go through.

We once were going to transport some real silver butter knives through TSA but decided otherwise because we recognized that a TSA officer could utilize discretion and confiscate them.

That’s why I recommend you to store your sharp objects in your checked baggage if possible.

Bringing knives in checked baggage

You may pack just about any type of knife in your checked baggage.

So your checked luggage would be the way to bring the following knives:

Bread knife
Butcher knife
Carving knife
Pocket knives
Hunter’s knives
Kitchen (or chef) knives
Paring knife
Santoku knives
Swiss Army Knife
Swords and sabers
Utility knife

But you still need to comply with the rules that relate to properly covering your knife.

TSA states that “[a]ny sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors.”

So you don’t want to have a knife sitting loosely in your checked baggage.

That’s because TSA may need to inspect your checked baggage and if you have an exposed knife sitting in your luggage they may not see it and could sliced her hand open.

Instead of creating that hazard, ensure that your knife is packed in such a way so that it is securely covered or wrapped just in case an inspector were start digging through your belongings.

Consider using covering the knife with a sheath, blade cover, or wrap the knife in cloth or bubble wrap. Even better if you can place the knife inside of a hard-shell case, perhaps with a label on it so that an inspector would know there is a knife inside.

Another easy way to protect your knife is to simply wrap it in paper.

Check out the video below which can be really useful, especially for people trying to bring multiple knives in their checked baggage.

What about other sharp items?

When in doubt about bringing a sharp item as a carry-on, just don’t bring it.

But if you’re trying to bring along a common sharp items like scissors then make sure you’re in compliance with the TSA rules. For example, you can bring scissors but only if they are less than 4 inches from the pivot point.

Here’s a list of common sharp objects that you might want to bring.

Below is a breakdown on whether or not they are allowed as carry-on items. Generally, you’ll notice that many small, common household items like safety pins and nail clippers are allowed.

Box Cutters = No
Cigar Cutters = Yes but not recommended
Corkscrews (with blade) = No
Crochet Hooks = Yes
Darts = No
Disposable Razor = Yes
Ice Axes/Ice Picks = No
Kirpans = No
Knitting Needles = Yes
Lock Picks = Yes
Meat Cleavers = No
Nail Clippers = Yes
Pencil Sharpeners = Yes
Razor-Type Blades = No
Sabers = No
Safety pin = Yes
Safety Razor With Blades (allowed without blade) = No
Saws = No
Sewing Needles = Yes
Swiss Army Knife = No
Swords = No
Throwing Stars = No
Tweezers = Yes

Knives and state laws

As a former attorney, I’m always thinking about the law and you should too if you are traveling with knives.

You have to remember that just because something is permissible through TSA, that does not mean that it is legal where you are or where you are going.

TSA is not a law enforcement agency so they are not actively trying to find out if you are breaking the law. Instead, they are primarily concerned with safety and preventing terrorist attacks via explosives and other dangerous items.

With that said, if they did find something illegal such as a type of knife that is not allowed in your state, they could refer you to law-enforcement.

That’s why you need to make sure that your knives are not going to get you into trouble wherever you’re going.

While all of the information in this article does not constitute legal advice, I provide some guidance that will help you in your own research. If you have any specific questions, be sure to get advice from an attorney before you risk breaking the law.

Each state will have its own laws that will determine if it is legal for you to possess or carry a knife. So it will be your responsibility to look up the latest laws to wherever you were traveling to.

So with all of that out of the way, here are some common restrictions that you can look out for and a few examples to help you along the way.

Blade length

A lot of states impose restrictions based on the length of a knife blade.

Typically, the limit is around 3 inches to 4 inches but some states go higher or lower.

Sometimes these apply to fixed blade knives but other times they only apply to switchblades. Some states also don’t publish any specific length limitations.

Carry open or concealed

Just like firearms, there can be laws pertaining to carrying knives open or concealed. And often these laws are tied to special blade length restrictions.

For example, states like Georgia, North Dakota, and Texas may permit pocket knives to be concealed if the blades are shorter than 5 inches. Other states have limitations at 4 inches or 3 inches.

Switchblades or automatic knives

Switchblades or automatic knives are those knives that pop out in an instant with the push of a button or the flip of a lever.

States often publish specific descriptions of what constitutes a switchblade and they usually refer to language like spring-loaded, relying on a throwing motion, gravity, etc.

These are outlawed at least in some degree in certain states like: California, Delaware, Hawaii, Massachusetts, Minnesota, New Jersey, New Mexico, New York, North Carolina, North Dakota, Pennsylvania and others.

Single-edged or double-edged blades

Some states put special restrictions on knives that have double-edged blades. It’s not uncommon to see a ban on double sided daggers, for example.

Disguised knives

Some knives are made to be concealed by looking like other objects such as pens or lipstick. These type of knives may be outlawed in certain states.

Also, if you get caught bringing these through TSA they can hit you with a bigger fine because of the concealment.

Special use laws

When it comes to carrying knives, context really matters.

For example, if you are out in the wilderness and with a knife the purpose of your use is probably survival, defense from wild animals, etc.

If you are wielding a knife in a packed subway station, that’s a very different matter.

Related to this, certain establishments like schools or bars have strict laws about carrying knives.

International travel with knives

When going through airport security in other countries you will face similar restrictions on bringing knives that you face with TSA.

Some may allow knives as long as they are no longer than 6 cm but others outlaw them entirely in carry on bags. At the end of the day, when flying international, it’s just a good idea to check with the airline you’re flying with.

With that said, here are some of the policies that I found.

In the UK, they state that “knives with a sharp or pointed blade and/or blade longer than 6cm” (2.3 inches) are not allowed in your carry-on (or what they call hand luggage).

The EU states, “Any sharp objects that might be used as weapons are not allowed in the aircraft cabin.” They go on to specify that “knives with blades of more than 6 cm” are outlawed.

So it’s basically the same policy as the UK.

In Canada, the CATSA states that knives over 6 cm must be packed in checked baggage when flying within Canada or to an international (non-U.S.) destination and that no knives are permitted in your carry-on on flights to the U.S.

Just like with laws in the US, different countries will have different policies on what type of knives are legally allowed. Here are some resources for you to check out when doing your research:

TSA Knives Rules FAQ

Can I bring a knife in my carry-on?

You are NOT allowed to bring a knife in your carry-on except for “plastic or round-bladed butter knives.”

What is a TSA approved knife?

There are no TSA approved knives except for “plastic or round-bladed butter knives.”

What is the fine for bringing a knife through airport security?

You could be charged a fine of over $2,000 if you are caught with a knife.

Can I bring a knife in my checked baggage?

Yes, You may pack knives in your checked baggage but you still need to comply with the rules of packing them safely.

TSA states that “[a]ny sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors.”

What if the knife is shorter than 2.36 inches?

Knives are no longer allowed even if they are shorter than 2.36 inches.

Can I bring a pocket knife on a plane?

You can only bring a pocket knife in your checked baggage.

Final word

Traveling with knives through airports is generally something I try to avoid. But when dealing with TSA you absolutely want to make sure that your knives are not in your carry-on so that you don’t get hit with a massive fine. Also, be aware that other sharp objects might not be allowed in your carry-on so always be on the lookout for restrictions.

TSA Body Scanners: Images & Machines Explained [2023]

If you have ever gone through a TSA body scanner there’s a good chance that you’ve wondered if your naked body is on display for someone in a mysterious back room.

It’s a valid worry but I think you’ll be happy to realize that you don’t have that much to worry about in today’s screening world.

Below, I will go into detail about TSA body scanners, the images that they display, and what it all means for your privacy, security, and health.

TSA body scanners used today

There are multiple different types of full body scan machines used by various security checkpoints but the two most relevant to TSA are Backscatter X-rays and Millimeter Wave AIT scanners.

Backscatter machines are the original body scanners used by TSA and those machines utilized X-rays which contained ionizing radiation.

However, the Millimeter Wave AIT scanners utilize microwaves which contain non-ionizing electromagnetic radiation.

Sounds scary, right?

But it’s not too far from that utilized by cellular data transmitters.

Check out the diagram below that shows off the electromagnetic spectrum with mircowaves on the left and X-rays on the right.

TSA currently uses Millimeter Wave AIT scanners exclusively, which are designed to peer through clothing to look for both metal and non-metal objects.

Brief history of TSA body scanners

TSA began deploying body scanners in 2010 and by the end of the year, the TSA had introduced 500 whole-body scanners at airports all across the US.

Why exactly were these “nudie scanners” added?

It had a lot to do with the 2009 underwear bomber attempt by Umar Farouk Abdulmutallab.

He was a Nigerian citizen who tried to blow up a Detroit-bound Northwest Airlines flight (on Christmas Day) by setting off explosives hidden in his underwear.

(It did not end well for him and he is currently serving four life sentences in a super max).

After this attempt, it became apparent to TSA that threats could be concealed beneath clothing and so they decided to introduce full body X-ray scanners.

These scans would presumably be more capable of detecting concealed metal, plastics, ceramics, chemical materials, and importantly, explosives.

The initial body scanners were very invasive and basically showed passengers near nude.

TSA tried to make up for this fact by allowing the agent who was doing the viewing to be seated about 50 to 100 feet away from the scanner.

That officer would then radio to another TSA officer who would actually do the follow up search if needed.

The thinking was that the officer who essentially saw you nude would never have any interaction with you.

TSA also stressed that the images were not saved or printed (although some images were saved and leaked in 2010).

You can see just how much detail they revealed in the images below. I edited one of the photos because they do show quite a bit of full frontal detail and my blog is (mostly) PG-13.

TSA body scan image man — The old body scanners showed near naked images of travelers.

You can see the unedited image here (partial male nudity).

Here is another image of a man and a woman and you can really see how something like a firearm and a knife would stand out.

This type of scanner did have some major concerns about its ability to detect objects but more on that below.

TSA full body scan image female and male gun

The images above may freak you out but you will be happy to know that TSA no longer uses the Backscatter X-ray scanners that produced these detailed images.

That is because in 2012 Section 739 of the FAA Modernization and Reform Act required that all full-body scanners operated in airports by the TSA use “Automated Target Recognition” software.

This replaced the picture of a near-nude body with a funny looking, avatar-like image.

The vendor of these machines initially was going to implement a software update on the Backscatter machines but they failed to do so.

Thus, the TSA removed Backscatter X-ray machines by May 2013.

That is pretty much the summary although there are new scanners that use passive terahertz technology which are being tested.

These can view travelers from far away as much is 25 feet. For now, we will just focus on the Millimeter Wave AIT scanners.

How the body scan process works

If you are in the standard security checkpoint line you will first be asked to remove some clothing items including your shoes, belt, jackets, and also accessories like watches, phones, etc.

You want to make sure your pockets are completely empty because the scanners can pick up even the smallest items, including small drugs.

You will then be waived through so that you are standing inside of what feels like an oversized phone booth.

Your legs should be spread apart a bit and then you will lift both of your arms and slightly bend your elbows.

Basically, you’ll look like you’ve been frozen mid jumping jack.

The antennas will then scan you within a couple of seconds and depending on the type of message that the TSA agent sees you will then be directed to proceed through security or undergo more screening.

If you have TSA Pre-Check, you can usually avoid the full body scanners.

In addition to offering you access to an expedited security line, TSA Pre-Check also provides you with the following perks:

Shoes can stay on
Belt can stay on
Light jackets can stay on
Laptops allowed to stay in bag
Liquids (3-1-1 Rule) can stay in bag

What does a TSA agent see from the body scanners?

Unlike back in the day where a TSA agent might see a near-nude image of your body, now a TSA agent will see one of two things after you are scanned.

If the scanner does not detect anything suspicious the screen will display the word “OK” with no image.

However, if the scanner detects something out of the ordinary there will be an avatar like outline of a human body (not your actual body) and wherever the suspicious item is detected, a yellow box will appear.

This is presumably where a TSA agent will want to search you to verify that the item is not a threat.

Declining the body image scanner

More than 99% of passengers choose to be screened by the full body scanners over alternative screening procedures.

If you are part of the one percent that would prefer not to go through the body image scanner you can avoid it but you will likely be subject to a type of physical screening such as a pat down.

This could be similar to a special SSSS search or a search you’d get if you didn’t have your ID.

There reportedly are some passengers who are not allowed to get by with just a pat down and have to go through the body image scanner but it seems like this is rare.

It could be random or in some cases you might be subject to secondary screening and need to consider a redress number.

Privacy issues

The big privacy issue that most people think about is the nakedness factor. Most people don’t like the thought of being gawked at by mysterious TSA workers behind a curtain.

But with the new software that TSA uses which doesn’t actually show bodily details that is not really a major concern for most.

I think a bigger issue is that the scanners could be tripped when they detect sensitive things like colostomy appliances, penile implants, and catheter tubes.

Another issue with these scanners is that I have heard they can pick up scar tissue very well.

So for example if you had had a mastectomy or some other type of major surgery it’s possible that your scar tissue could trigger the scanner and force you to undergo an additional search in a sensitive region.

There’s also the issue of gender identity.

At least at one point the scanners were set to trip if they detected certain body parts that did not align with the gender they were programmed to be reviewing.

You could imagine how that could cause major issues for a lot of transgender people and inexperienced TSA agents who may not know how to properly handle the situation.

As more state IDs allow for non-binary people to select gender neutral or “X,” I would think these problems would decrease, but I’m not exactly sure how the gender selection process works with TSA’s software.

The good side of TSA scanning technology is that some believe that some of the scanners could be used as a potential to be a skin cancer diagnostic tool for finding early signs of malignant melanoma — a very serious type of skin cancer.

Safety & health concerns

Anytime you are dealing with waves being sent to or through your body there are always going to be questions about the safety of it all.

The Backscatter machines used X-rays which are ionizing radiation, and “more energetic than millimeter waves by more than five orders of magnitude.”

In short, the old machines were much more dangerous than the new ones.

But what about the radiation potential of the Millimeter Wave AIT scanners?

One major authority on this topic, Thomas S. Tenforde, president of the National Council on Radiation Protection and Measurements, said in 2010 that the scanners were probably within bounds [of standards for safe operation].

But he also emphasized that there should be an effort to verify that they are safe for frequent use.

A more recent study allegedly called the safety of these AIT scanners into question but other fact checkers have refuted/de-bunked these claims and clarified that there is no risk of DNA damage.

(The main study relied upon to call the safety of these scanners into question did not even focus on airport scanners.)

The reason why these millimeter waves are not viewed as very dangerous is that they are much larger than x-rays and do not involve ionizing radiation.

Ionizing radiation is the type of radiation that can alter the structure of molecules but this scanner does not emit that type.

Instead, it emits a type of microwave that is “thousands of times less than that of a cell phone transmission.”

Effectiveness

Many people question whether or not these full body scanners are actually effective.

Actually, the backscatter scanners were shown to be at least somewhat suspect at detecting weapons. They also were potentially subject to getting hacked with malware.

I also read that there were some tests done that showed the scanners did not detect a handgun hidden under an undercover agents undergarments.

However, this could be say more about the people monitoring the images than the machines.

I know from my personal experience that even the slightest object can trigger the scans. I once left a small painkiller tablet in my pocket and the agent was instantly notified and asked me to empty the pocket.

If anything the scanners might be overly sensitive.

One issue with the scanners is that there are some types of materials that make false positives more common such as folds in clothing and buttons.

Also, beads of sweat can trigger false positives on the scanners.

Just how common are false positives? Some countries, such as Germany, have reported a false-positive rate of 54%.

I don’t believe that the TSA body scanners can penetrate through your skin like other X-ray machines do.

So for example they would not detect things like tampons or menstrual cups inside your body from what I can tell.

However, please don’t try to sneak through TSA by sticking items in your bodily cavities.

If you are trying to smuggle drugs that way there are dogs that are trained to sniff drugs including those located in your bum or elsewhere.

Also, I’m pretty sure that if authorities suspect that you might be holding something inside your body they can order you to take a type of X-ray that will reveal items in your body cavities.

TSA Body Scan FAQ

What type of body scanner does TSA use?

TSA currently uses Millimeter Wave AIT scanners which use a form of electromagnetic radiation known as microwaves. These type of body scanners do not use X-rays.

Are the TSA body scanners harmful to pregnant women?

Millimeter Wave AIT scanners emit a type of microwave which is non-ionizing radiation. According to the Centers for Disease Control and Prevention (CDC), “common exposures to non-ionizing radiation are not considered hazardous to you or your unborn baby.”

Do the TSA full body scanners emit harmful radiation?

Millimeter wavelength radiation is used in the TSA full body scanners but it is non-ionizing and therefore incapable of causing cancers by radiolytic DNA bond cleavage. To date, there is not any evidence of harmful effects other than those caused by localised heating.

Can TSA seen you naked?

No, TSA cannot see you naked when they view the display screen from the full body scanner. Instead, they see a cartoon like representation of a human with highlighted sections if a suspicious item is detected.

Why does TSA use the body scanners?

After the underwear bomber’s attempt in 2009, it became more apparent that threats could be hidden beneath clothing, so TSA wanted a way wait to view potential explosives hidden under cloth.

Can I avoid the TSA full body scanners?

Yes, most passengers can opt to avoid the full body scanner but they will likely be subject to a pat down. Also, those with TSA Pre-Check can avoid the body scanner.

Does TSA save the body scan images?

No, in fact the scanning devices are not supposed to allow TSA to store any of the images. However, in the past some images (35,000) were being saved and some even got leaked.

Final word

Hopefully after reading this article you are a little bit relieved and you learned something about the evolution of the TSA full body scanner.

If you are at all bothered by the scanner I would highly recommend getting TSA Pre-Check so that you can avoid the scanner for the most part.

And just remember the privacy concerns are not nearly as bad as they once were and there is no evidence that you are subject to dangerous radiation.

TSA Liquid Rules Ultimate Guide (3-1-1 Explained) [2023]

Bringing your liquids through airport security is not always as straightforward as you might think.

There are several rules that apply when bringing your liquids through airport security checkpoints and, yes, many are obvious to those of us blessed with a shred of common sense.

But in some cases there are some less obvious restrictions that could apply to your liquids.

And when you start talking about things like baby essentials, medications, and liquids like alcohol, there are many lesser-known rules and exceptions that come into play.

Violating these rules can sometimes mean slowing down the flow of the screening checkpoint (something we all should want to avoid) but in other cases it could mean violating the law and you basically becoming an airport criminal.

And nobody wants that.

So it’s a good idea to get acquainted with how these rules work and in this article, I’ll give you a detailed breakdown of the 3-1-1 rule and also talk about the many different types of exceptions and additional rules that apply to different types of liquids such as medications and alcohol.

What is the TSA Liquids “3-1-1 Rule?”

The TSA Liquids 3-1-1 Rule states that you can only bring liquids in containers no larger than 3.4 liquid ounces (100 milliliters) and that all of your liquid containers must fit “comfortably” into one clear, quart-size bag.

Where does the 3-1-1 come from?

It’s just an easy way to memorize the different requirements that make up the rule and I’ll hit on those below.

3.4 fluid ounces or (100 mL)

The “three” indicates that your liquids must be contained within a container no larger than 3.4 fluid ounces or (100 ml).

(TSA uses 3.4 ounces because it’s easier to remember but really 100 ml comes out to 3.3814 fluid ounces.)

One of the biggest things that people get confused about is that the 3.4 ounce requirement applies to the size of the container and not the liquid within the container.

So let’s say that you have a 6 ounce container with only 2 ounces of fluid inside.

You may think that because you have under 3.4 fluid ounces of liquid, you are good to go but because your container is larger than 3.4 ounces, you cannot bring that through TSA.

The other big thing to know is that this refers to fluid ounces which relates to volume and is very different from ounces used for weight.

Some products like honey could weigh 4 ounces but still fit inside of a 3.4 fluid ounce container. It helps to know how to convert ounces/grams to fluid ounces.

1 quart-sized resealable bag

The first “one” means that your liquids must fit within 1 quart-sized resealable bag. Typically, this will be a clear Ziploc bag which just makes things easy for everybody.

The key thing to note here is that the containers must fit “comfortably” inside this resealable bag.

What does “comfortably” mean?

It basically just means that the bag is not bursting at the seams. (Think about how a pair of jeans should fit when you’re being honest with yourself about your waist size.)

If you are not able to easily reseal your bag, then your contents may not be fitting comfortably inside.

In such a scenario, it’s possible that a TSA agent could ask you to throw something out in order to allow your bag to comply with the rules.

In my personal experience, I have not seen a lot of TSA agents enforce the “comfortable” requirement very strictly but if you have bottles poking out of your liquids bag, I could see that being an issue.

1 quart size bag per person

The last requirement is that you are allowed 1 quart size bag per person.

The easiest way to comply with this is to simply separate your liquids bag from your carry-on and have one liquids bag in your bin when going through security.

Otherwise, it could look like you are trying to bring through two bags of liquids.

The best packing tip I have for this is to keep your liquids bag at the top of your carry-on so that you can easily retrieve it.

There’s nothing worse than scrambling to find that liquids bag while trying to get ready to go through a screening checkpoint.

TSA Pre-Check liquids rule

TSA Pre-Check allows you to bypass the main security line and pass through a screening line that is usually much shorter and quicker. This also means avoiding the full body scanner in many cases. It basically makes you a VIP when it comes to airport security checkpoints.

If you have TSA Pre-Check, you can take advantage of several benefits including things like:

Shoes can stay on
Belt can stay on
Light jackets can stay on
Laptops allowed to stay in bag
Liquids (3-1-1) can stay in bag

That last perk is the most relevant to the liquids rule as you will not have to remove your liquids bag and place them in one of the bins when going through security. You can simply leave them in your carry-on and pass through the metal detector without any issue.

I highly recommend that you look into getting Pre-Check in order to expedite your security screening. It will only cost $78 for five years and all you have to do is pass a background check. You can also get it if you are approved for Global Entry (read how to get approved here).

New hand sanitizer liquids rule

Due to the ongoing threat of coronavirus and the potential threat of spreading germs throughout airports and aircraft, TSA recently implemented a change with respect to hand sanitizer.

Passengers will now be allowed to bring one hand sanitizer bottle up to 12 ounces. These larger bottles will be screened separately so just be aware that it could add some extra time.

What exactly is a “liquid?”

In some cases, what constitutes a liquid will be very clear.

For example, it’s pretty much common sense that water inside of a water bottle is a liquid. The same applies for cologne, mouthwash, etc.

But liquids also can include less-obvious forms like aerosols, gels, creams, or pastes.

This means that several common items you would be bringing along for your trip could be considered a liquid like: toothpaste, lotion, sunscreen, shaving cream, shampoo, conditioner, and others.

You can find travel-sized products for most of these so it’s usually pretty easy to bring along items that comply with the TSA liquids rule.

Other items

You need to be mindful of other items that could be considered liquids like deodorant. For example, the following types of deodorants will be subject to the 3-1-1 rule:

Spray
Gel
Liquid
Cream
Pastes
and Roll-On deodorants

Prohibited items

Just because you have something like an aerosol and it is in a container no larger than 3.4 ounces, that does not mean that you can bring it as a carry-on.

There are quite a few prohibited items like aerosol insecticide, bear spray, etc. that are not allowed as carry-ons. In fact, some of those items may not even be allowed on the plane at all. This is a good place to search if you are in doubt about whether or not you can bring a particular item.

Be aware that some items like hairspray may even have size restrictions when packed in your checked baggage.

Picture of shaving cream going into hand — Liquids can come in many different forms.

Foods can also be liquids

One aspect of the TSA liquids rule that throws a lot of people off is that they forget many foods also qualify as liquids.

Here is a non-exhaustive list of food items that will fall under the liquids rule:

Liquid chocolate
Creamy dips and spreads
Mashed fruits such as applesauce
Gravy
Honey
Jam and jelly
Maple syrup
Oils and vinegars
Peanut butter
Wet pet food
Salad dressing
Salsa and sauces
Soups
Yogurt

Basically anything that is usually poured, scooped, squeezed, slurped, or mashed will be considered a liquid for TSA purposes.

If your food is solid on the other hand, chances are you can bring it through.

Picture of a bowl of hummus — Hummus is a liquid in the eyes of TSA.

TSA rules for liquid medications

The liquids rule provides exceptions for medical supplies and medications.

TSA allows larger amounts of medically necessary liquids, gels, and aerosols in “reasonable quantities” than your 3-1-1 allowance.

You do not have to have a prescription for these items but keep in mind that you need to comply with state laws regarding prescriptions and controlled substances.

This leaves two questions often to be asked and answered.

The first is what is considered “medically necessary?”

For example, is contact lens solution medically necessary?

It seems the answer to that is probably yes given the TSA states, they allow “larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip” on the page regarding contact lenses.

So if in doubt check the website and then inquire with AskTSA if you still don’t know.

The second question is what is considered a “reasonable quantity?”

What is deemed as a reasonable quantity is a subjective determination.

According to the TSA, you should bring what’s necessary for the duration of your trip (e.g., seven days) plus a day or two just in case things get delayed or canceled.

If you stick to what you think will be necessary for the duration of your trip, I don’t think you will often run into trouble. But if you’re bringing a six month supply of medication on a four day getaway, that’s when you might start to run into trouble if questioned.

TSA states that you must declare them to TSA officers at the checkpoint for inspection.

You also want to remove these from your carry-on so that they can be screened separately from your belongings. (You do not have to put your liquid medication in a plastic Ziploc bag.)

Just be aware that if one of your liquid items declared as medically necessary sets off the alarm, it may require additional screening and may not be allowed.

Baby essentials

You are allowed to bring formula, breastmilk, and juice for infants or toddlers in “reasonable quantities” through airport security. According to the TSA, reasonable quantities for baby essentials typically means the duration of the flight.

When bringing these items through security, be sure to separate these from your carry-on bag so that they can be screened separately from the rest of your items.

If you are carrying liquids in excess of 3.4 ounces, you are advised to inform the TSA officer at the beginning of the screening process that you have excess liquids. You can do this when you are unloading your items into the bin.

In many cases, excess liquids will be screened by x-ray.

It’s also possible that an officer may ask you to open up the container and potentially even transfer a small quantity of the liquid for testing.

If you are worried about the effects of an x-ray machine on your liquids, The Food and Drug Administration states that there are no known adverse effects from eating food, drinking beverages and using medicine screened by X-ray.

If that is not good enough assurance for you, you can ask to avoid the x-ray machine.

Additional steps may be able to be taken to clear the liquid but the traveler will likely have to undergo additional screening procedures which could include a pat down and a thorough screening of all of your carry-on property.

You will also be allowed to bring along ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk and juice.

If these are in a partially frozen state or perhaps appear like a slushy they will be subject to the same screening as described above.

Other permitted baby items include gel or liquid-filled teethers, canned, jarred and processed baby food.

Just always be aware that these items may have to undergo additional screening.

TSA liquid rules for alcohol

Bringing alcohol through TSA presents a number of different challenges.

First, your alcohol in most cases will have to comply with the liquids 3-1-1 rule. This means that you won’t be able to bring in regular bottles of liquor or beer.

It is possible to find small bottles that are under 3.4 ounces (mini-liquor bottles are often around 1.7 ounces, so this means that they are small enough to be brought on the plane as a liquid).

But contrary to what many people think, it’s also permitted to bring your own alcohol in one of your own containers.

The catch is that there are specific restrictions about what type of alcohol is allowed on board and that can be allowed as a carry-on. You really need to make sure that you are abiding by these rules because you could be violating federal law otherwise.

The first regulation to know is that alcohol beverages with an alcoholic percentage above 70% (140 proof) is never allowed on the plane. In fact, alcohol with such a high alcohol percentage is considered a hazardous material.

If the alcohol content is above 24% but not above 70% then the alcoholic beverage must be in its retail packaging. A lot of popular alcoholic beverages for within this range. Here are some ranges for the alcoholic content of some common beverages:

Alcohol Percentage Content

Vodka | ABV: 40-95%
Gin | ABV: 36-50%
Rum | ABV: 36-50%
Whiskey | ABV: 36-50%
Tequila | ABV: 50-51%
Liqueurs | ABV: 15%
Fortified Wine | ABV: 16-24%
Unfortified Wine | ABV: 14-16%
Beer | ABV: 4-8%
Malt Beverage | ABV: 15%

And finally, one of the most important things to remember is that you are not allowed to serve yourself your own alcohol when flying.

Instead, you must request a flight attendant to serve you the alcohol or else you will be violating FAA regulations. Some flight attendants will happily serve you your own beverage but others will not be so inclined.

If you purchased alcohol at duty free store, different rules apply in that scenario. Basically, you can bring your duty free alcohol through TSA security but you have to comply with three separate requirements:

The duty free liquids were purchased internationally and you are traveling to the United States with a connecting flight.
The liquids are packed in a transparent, secure, tamper-evident bag by the retailer and do not show signs of tampering when presented to TSA for screening.
The original receipt for the liquids is present and the purchase was made within 48 hours.

Read more about this rule here.

Checked baggage liquid rules

Many times, you can simply place your liquids in your checked baggage and not have to worry about that pesky 3-1-1 rule.

This is usually the way to go on longer trips when you might be bringing large quantities of things like shampoo or shaving cream.

But as mentioned above, you still need to make sure that the type of liquid is allowed on a plane. Certain materials may be considered hazardous and you could be violating the law by bringing those on board.

If you are loading up your checked baggage with a bunch of liquids, make sure that you double bag if there is potential for the liquids to spill!

TSA Liquid Rules FAQ

Does the TSA liquid rule apply to checked baggage?

The TSA 3-1-1 rule does not apply to checked baggage. However, there are some restrictions on what liquids can be transported in your checked baggage. There may also be limitations on the quantity of liquids when it comes to importing large quantities of things like alcohol. At some point, you might have to obtain a license for certain goods.

Does TSA enforce the liquid rule?

TSA definitely enforces the liquids rule and I would recommend not trying to circumvent the rule. It’s possible that an agent may be more lenient than another in certain circumstances but I would always assume that an agent will be enforcing strictly so that I don’t run into any unexpected issues.

Why does TSA have liquid rules?

TSA has the rules in order to detect potential explosives and other harmful materials that exist in liquid state.

Does TSA have special liquid rules for international travel?

The same liquid rules apply for both domestic flights and international flights.

One difference that you might encounter is when you purchase duty free goods before an international flight. See the duty-free section above for more details.

Also, when flying internationally it is recommended that you get to the airport extra early. It is possible that you could get hit with SSSS and be forced to undergo a heightened security screening, so always plan out extra time.

What are the TSA liquid rules for makeup?

While you might view your makeup as special, there are no special rules for your makeup when it comes to TSA. They must abide by the same 3-1-1 rule explained above. Read more about makeup rules here.

Do you have to remove liquids for TSA Pre-Check?

No, you do not have to take out your liquids if you have TSA Pre-Check.

Do airlines have different rules for liquids?

The same TSA liquids rule will apply to all airlines. So if you’re flying American or Delta, the rules will be the same as if you were flying Southwest or United.

With that said, some airlines do have some differences in how they handle acceptable baggage so you should make sure to read up on the latest baggage policies for the airlines.

What rules apply to powders?

If you are traveling from an “international last-point-of-departure” to the U.S., powder-based substances in carry-on baggage greater than 350mL or 12 oz. may require additional screening. If your substance is over 12 ounces and cannot be cleared it will not be allowed onto the aircraft cabin.
TSA recommends that you transport powders in your checked baggage.

Final word

TSA has several rules you need to follow when it comes to drinking liquids through airport security. The most well-known is the 3-1-1 rule but there are other considerations you need to think about like foods that might trigger the rule and exceptions for medical and baby essentials. In the end, try to be as reasonable as possible with what you are bringing through and you will run into few problems.

TSA Approved Gun Case & Ammunition Guide [2023]

Are you thinking about bringing your guns/firearms and/or ammunition through the airport and on to your next destination? If so, there are some specific TSA rules related to traveling with guns that you need to know about before you ever set foot in an airport. In this article, I break down all the rules for TSA approved gun cases and also provide you with links to all of the firearm policies for the major US airlines.

Can you bring firearms through the airport?

Yes, you may transport unloaded firearms in a locked hard-sided container but as checked baggage only. Some of the things to keep in mind are that the guns need to be unloaded and the container needs to:

Have a lock
Be hard-sided
Transported with checked baggage

Keep reading below for more details on the rules.

Firearm transport restrictions: 8 things to know

1. State and local laws

When traveling to and from the airport, remember to comply with the laws concerning possession of firearms since these can differ a lot, depending on the city, state, etc. For a list of relevant laws pertaining to traveling with guns in every state click here.

2. What is a “firearm?”

It’s a good idea to check with your airline to see what exactly is considered a firearm if you are on the fence. For example, here’s the definition of firearm provided by Alaska Airlines:

A “firearm” is any weapon that will, or is designed to, or may be readily converted to expel a projectile by the action of an explosive, or the frame or receiver of any such weapon. This includes:

Sporting rifles, shotguns, and handguns
Handguns of authorized law enforcement officers while traveling on official duty
Starter pistols, compressed air or BB guns, and flare pistols
Antique firearms
Silencers/suppressors

Notice that even BB guns fall under this category. If you have a paintball gun they might not be subject to the container requirements. For example, Southwest states that “[p]aintball guns are allowed in checked baggage and are not subject to the container requirements of firearms.” Just check with your airline if you are in doubt.

3. International travel with firearms

If you are traveling internationally with a firearm in checked baggage, you should check with the U.S. Customs and Border Protection website for information and requirements prior to travel.

Here’s what the CBP states:

Current export regulations issued by the Department of State require travelers to file Electronic Export Information (EEI) for temporary export of personally owned firearms via the Automated Export System (AES) prior to departure from the United States.

You will likely need to complete a CBP Form 4457. Once the CBP 4457 is completed, it can be used over and over again for the same firearm. You also want to get familiar with the import requirements of the foreign country(s) (the CBP Form 4457 may be required for entry). For more on international firearm travel regulations click here.

4. Firearm must be unloaded

When you are traveling with your firearm through an airport, it must be unloaded. 49 CFR 1540.5 defines what a loaded firearm is and states that:

Loaded firearm means a firearm that has a live round of ammunition, or any component thereof, in the chamber or cylinder or in a magazine inserted in the firearm.

Some also recommend locking the slide back to show that the gun is not loaded. But just make sure that the gun is not loaded or you could face some harsh consequences like getting fined or even criminal consequences.

5. Choosing a container and lock

Firearms must be unloaded and locked in a hard-sided container and transported as checked baggage only. Sometimes multiple locks may be required or used to secure the baggage. (You are usually NOT required to place locks in every available hole on the case, as long as the case is secure.)

Only the passenger should retain the key or the combination to the firearm lock. The exception to this is if TSA personnel request the key to open the firearm pursuant to TSA regulations for inspection. This means that you need to be on alert as you make your way through the terminals just in case your are paged by airport agents that they need to inspect your container after you have checked it.

You may use any brand or type of lock to secure your firearm case. I would not go with a container that has a “TSA approved” lock on it (the type of lock that TSA agents can open up), since you want to avoid as much potential tampering with your firearm as possible.

Here are some links to TSA compliant firearm containers, many of which are on the cheaper side. Keep in mind that you don’t have to use a “firearm” case. Any hard-sided case that can be securely locked will suffice, even if it’s not specifically designed for firearms.

6. Declaring your firearm (checking-in)

Once you arrive at the airport you need to declare the firearm and/or ammunition to the airline when checking your bag at the ticket counter (you can’t check your firearm at the curb). This process could take some extra time to complete so you don’t want to be rushing through the airport when you’re traveling with a firearm — give yourself a little bit of extra time.

You’ll have to read and sign a tag ensuring that you are complying with all the firearm regulations and then insert that tag into your firearms bag. The TSA inspection will take place at the check-in counter or may take place at another TSA area.

The container that you choose to use must completely secure the firearm from being accessed. If the locked case can be easily opened it will not be permitted. You should note that the container the firearm was in when purchased may not adequately secure the firearm when it is transported in checked baggage.

Declare each firearm each time you present it for transport as checked baggage. Ask your airline about limitations or fees that may apply. You can read the policies for each major US carrier below:

I would recommend for you to print out/download the policy for the airline that you’re flying with to ensure that the process runs smoothly. Sometimes airline agents don’t know their own policies and will assume how things should work and you’ll have to check them which is easy to do when you have their policy on you.

7. Firearm parts

Firearm parts cannot be transported in your carry-on bags. So things like magazines, clips, bolts, and firing pins, must be transported in checked baggage. Also, replica firearms (even toys) must be transported in checked baggage only. However, rifle scopes are permitted in carry-on and checked baggage.

8. Ammunition

Ammunition is prohibited in carry-on baggage, but small arms ammunition may be transported in checked baggage when being transported securely for personal use according to 49 CFR 175.10 (a)(8).

Small arms ammunition includes cartridges up to 19.1 mm (.75 caliber) and shotgun shells of any gauge. (It does not include black powder, smokeless powder, primers, percussion caps, or homemade powder and ball loads for muzzle loading.)

Firearm magazines and ammunition clips, whether loaded or empty, must be securely boxed or included within a hard-sided case containing an unloaded firearm.

You can store your small arms ammunition in the same hard-sided case as the firearm or in a secured box made up of certain materials. TSA states that, small arms ammunition “must be packaged in a fiber (such as cardboard), wood, plastic, or metal box specifically designed to carry ammunition.”

The federal regulation that speaks on this is 49 CFR 175.10 (a)(8) and it states:

(8) Small arms ammunition for personal use carried by a crewmember or passenger in checked baggage only, if securely packed in boxes or other packagings specifically designed to carry small amounts of ammunition. Ammunition clips and magazines must also be securely boxed. This paragraph does not apply to persons traveling under the provisions of 49 CFR 1544.219.

Also, you should check with your airline if ammunition is allowed in checked bags.

The risk of getting fined by TSA

TSA can fine passengers for violating certain rules and the fines for failing to abide by the transport rules for firearms are some of the biggest penalties.

So make sure that you properly package your firearm and that it is not loaded when you arrive at the airport because that is one of the major violations.

And also, always triple check that your firearm is not in your carry-on bag because taking a firearm through airport security, especially if you have access to ammunition, could result of a hefty fine (along with referral to law-enforcement).

Firearms through the airport FAQ

What is considered a firearm?

Typically a firearm will include:

Sporting rifles, shotguns, and handguns
Handguns of authorized law enforcement officers while traveling on official duty
Starter pistols, compressed air or BB guns, and flare pistols
Antique firearms
Silencers/suppressors

If you have any questions, be sure to check with the airline you are flying with.

Can I bring a firearm on an international flight?

You may be able to bring your firearm on international flights in your checked baggage. However, you may have to fill out extra paperwork including a CBP Form 4457.

Does my firearm need to be unloaded?

When traveling through an airport with your firearm, it must be unloaded or you might be subjected to a large fine and/or face criminal consequences.

Can I bring ammo in my carry-on?

No, you are not allowed to bring ammunition in your carry-on.

Final word

The rules aren’t that complex when it comes to traveling with firearms through airports. The key is to make sure you get a TSA-compliant case that has a hard shell and comes with a key lock or combination lock. Also, it’s very key to remember to unload the weapon before storing it. And if you’re planning on traveling internationally, you should do some research on the regulations in the country you’ll be arriving in.

TSA Razor Rules: What Types of Blades Are Allowed on a Plane? [2022]

There are a lot of common items that people ask about when it comes to TSA rules.

I’ve seen a lot of questions related to things like food, alcohol, deodorant, and a lot of other commonly used products. Another common product often asked about is: razors.

In this article, I will tell you everything you need to know about the TSA rules for razors, so that you don’t end up in a prickly situation.

I’ll break down the different types of razors you might be concerned with (disposable, electric, etc.) and give you some good options for TSA-approved razors.

What are the TSA rules for bringing razors on planes?

TSA will allow you to bring disposable razors and electric razors in your carry-on but other types of razors like safety razors and straight edge razors are not allowed through airport security checkpoints.

However, you can bring virtually any type of razor in your checked baggage. You just need to make sure that the razor is properly packaged so that if an agent inspects your bag, they will not get injured while digging through your luggage contents.

Keep reading below to find out more details!

Bringing razors in your carry-on or checked baggage

If you are bringing some of the TSA approved razors talked about below in your carry-on you don’t have to remove them but it would probably help if you separated them from other items in your bag for easy access.

If you are bringing razors in your checked baggage the main thing you need to focus on is properly covering your razors so that an agent will not get cut by them if they are digging through your luggage during an inspection.

A lot of razors come with protective covers and so those can help prevent injury by snapping those on. In other situations, you could wrap your razors in several layers of paper and then tape them up.

Disposable razors (TSA approved)

If you use disposable razors, you are in luck because you will be allowed to bring your disposable razors through TSA airport security and onto the plane as a carry-on. These include those razors made by: Bic, Dollar Shave Club, Gillette, Harry’s, Schick, and Solimo.

These brands offer two different types of disposable razors.

The first is the type of razor that you throw away entirely (there is no razor blade cartridge).

These can be very economical and you can find a dozen of these for under $20. (Personally, I don’t like using these cheaper razors but that’s just me, everyone’s face, legs, body, etc. is different.)

The other type of disposable razor utilizes a cartridge so you only throw away the cartridge but you keep the handle and simply add a new cartridge.

These are my favorite types of razors and I’ve been loyal to the Gillette Fusion5 Proglide (for men’s shaving) for a very long time. Gillette also makes quality women’s razors.

All of these disposable razors are allowed by TSA.

The thinking, I believe, is that it’s difficult and/or time consuming to remove the blades from the razor and the blades are generally small so they don’t pose that much of a threat.

So if you’re bringing along disposable razors, you can pack them in a carry-on or checked luggage.

Electric razors (TSA approved)

You might be a little bit more fancy and go with an electric razor when you shave.

If that is the case then you are also in luck because you are allowed to bring electric razors through TSA security and onto the plane.

Electric razors come in a few different forms, but generally these are those razors that can be used on wet or dry skin and come with those funny looking heads.

Because these are electronics and sometimes look odd, the TSA agents may want to take a closer look at your electric razors sometimes but it shouldn’t be an issue.

So you can bring electric razors on as a carry-on item or in your checked luggage — it is all up to you.

By the way, hair clippers are also allowed as carry-ons or checked bag items.

Rechargeable beard trimmers are also allowed in both carry-on and checked bags.

Battery chargers are allowed in carry-on and checked bags. (If your trimmer charger has an electrical cord, be sure to wrap it tightly around the charger.)

Just remember that spare lithium batteries are prohibited in checked baggage.

Safety razors (NOT TSA approved)

Safety razors are those razors that are sort of in between straight edge razors and disposable.

Many people swear that these are better than disposable razors although that probably comes down to the type of skin and the coarseness of your hair.

Anyway, these razors are great because they can use high quality razors and also it can be cheap to replace the razor blades, allowing you to take advantage of some serious long-term savings compared to disposable razors.

You can find some quality safety razors online for under $20 though high-quality safety razors can be much more expensive.

However, these are not TSA approved.

It doesn’t matter if you’re dealing with open comb, closed comb, etc., if you have a safety razor, you can only bring the handle and not the razor with you through as a carry-on.

Instead, the razors must be checked in your checked baggage.

Straight edge razors (NOT TSA approved)

You probably won’t be surprised to find out that straight edge razors are NOT allowed through TSA security.

Straight edge razors are those old-school grooming razors that you can find many barbers using. They are long and some people find them pretty terrifying when positioned close to their face or throat.

These obviously pose more of a threat to flight attendants and passengers and so understandably you cannot bring straight edge razors onto a plane.

Instead, the razors must be stored in your checked baggage, though you can bring the handle on if they don’t contain a razor.

Box of razors

You cannot bring a box of razors in your carry-on.

However, you would be allowed to bring in a package of razors if all of the razors are in a cartridge.

For example, if you had the Gillette Fusion ProGlide Razors disposable cartridges mentioned above those could be brought in your carry-on by themselves.

What about shaving cream?

You might also be curious about the rules for bringing shaving cream through airport security.

Shaving cream will be treated like a liquid and therefore subject to the TSA 3-1-1 liquids rule.

This just means that any container of shaving cream must be no larger than 3.4 fluid ounces and must be placed in a clear zip lock bag no larger than a quart to bring it as a carry-on.

Make sure that you also keep the cap on the shaving cream can because if it is missing, TSA may confiscate your shaving cream.

If you have a large container of shaving cream, then you will need to put that in your checked luggage. Just be aware that there are limitations on shaving cream in your checked baggage.

Shaving cream is considered a hazardous material but you will still be allowed to bring containers up to 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).

It should be very easy to find shaving cream cans much smaller than 17 fluid ounces.

Your total aggregate amount of these restricted items cannot be more than 2 kg (70 ounces) or 2 L (68 fluid ounces).

So just remember that if you also had something like hairspray you would have to add that to the aggregate total and remain under 68 fluid ounces.

What about other sharp objects?

You might be wondering about other sharp objects like knives.

You are allowed to pack certain types of knives and pocket knives in your checked baggage but these cannot be brought on as carry-ons.

The only types of knives that are allowed as carry-ons or plastic or round pleated butter knives.

It’s good to remember the rule of thumb that you are generally prohibited from traveling with any sharp objects in your carry-on baggage.

You can actually get hit with a pretty hefty fine if you are caught with certain band objects that fall in the category below:

Axes and hatchets; bows and/or arrows; ice axes and ice picks; knives with blades that open automatically (such as switchblades); knives with blades that open via gravity (such as butterfly knives); any double-edge knives or daggers; meat cleavers; sabers; swords; and machetes throwing stars
