United Airlines Pet Policy (International, Cargo, Carry-on) [2023]

There are a few different United Airlines pet policies depending on how and for what purpose you’re bringing along your animals.

This article will take a detailed look at the pet policy for shipping animals on United.

I’ll cover in-cabin transport (carry-on), PetSafe (cargo), international, service animals, and show you where to go to get all of the forms and documents you’ll need to transport your animals.

What is the United Airlines pet policy?

United Airlines will allow pets to fly in-cabin but they no longer offer the ability to fly pets in the cargo hold as part of the PetSafe program (except for limited exceptions for the military).

The pet policies require you to follow some very specific rules and guidelines so if you’re thinking about transporting your pets on United you need to pay very close attention to the different rules.

How to avoid United pet fees

One of the easiest ways to avoid pet fees is to use the right credit card. The Capital One Venture Rewards Credit Card is a good card for general travel expenses and its points can be used to offset airline pet fees since they will often code as travel.

You can also use an incidental credit attached to a travel credit card. For example, the Platinum Card has a $200 incidental credit.

Other cards like the Chase Sapphire Reserve have a $300 travel credit that could be used on virtually any type of travel purchase including pet fees.

United in-cabin animals

In the past, United stated that they would allow domesticated cats, dogs, rabbits and household birds (excluding cockatoos) to travel accompanied in the aircraft cabin on most flights within the U.S.

They recently changed their website and now do not list out all of the different animals so it’s not clear to me what pets they allow beyond cats and dogs. For that reason, you may want to call and clarify what animals are allowed.


The fees for an in-cabin pet are $125 each way. Also, there is an additional $125 service charge for each stopover of more than four hours within the U.S. or more than 24 hours outside of the U.S.


Booking a ticket for your pet is very easy to do with United.

Whenever you are making a booking, just be sure to select “Travel with a pet” as a traveler. If you already made a booking, you can still go to My Trips and add a pet to an existing trip. You cannot add a pet using the United app.

Do everything you can to make this reservation in advance because there are limited slots available for pets on aircraft.


Whenever you arrive at the airport, be sure to check in and get your pet tag. Remember, you’ll need both your own and your pet’s confirmation numbers.

Also remember that your pet is expected to remain in the kennel while in the airport. If you need to take them to a relief area you can check the airport maps feature on the United app to see if you can find one.

Kennel rules

Before your bring your pet on-board, make sure that you are towing them in a kennel that complies with the United pet policy rules.

The kennel must fit completely under the seat in front of the customer and remain there at all times and the door needs to be secured as well.

Also, the animal must be able to stand up and turn and around inside the kennel. There may only be one pet per kennel.

There are also specific dimensions required for these pets:

  • Hard-sided kennels: 17.5 inches long x 12 inches wide x 7.5 inches high (44 cm x 30 cm x 19 cm).
  • Soft-sided kennels: 18 inches long x 11 inches wide x 11 inches high (46 cm x 28 cm x 28 cm).

United will allow you to bring along soft-sided pet carriers that slightly exceed these dimensions so long as they don’t block the aisle.

While your pet must remain under the seat, some people will purchase an extra seat because it makes it easier to deal with their pet.

For one, it gives the passenger space to put a personal item underneath the difference seat. It also allows them to more easily bend over to check on the animal.

No unaccompanied minors

Pets are not allowed to travel with unaccompanied minors.

Age limits

Puppies and kittens traveling within the U.S. and Puerto Rico must be at least 2 months (8 weeks) old to be accepted for travel on United. Puppies and kittens traveling internationally must be at least 4 months (16 weeks) of age to be accepted for travel on United.

International travel

Pets are not permitted on flights to, from or through Australia, Hawaii, New Zealand and other locations. Please verify if your destination allows in-cabin pets prior to travel.

Rules for international in-cabin pets vary. To book international in-cabin travel for a pet, contact the United Customer Contact Center or call 1-800-864-8331 to add a pet to your reservation.

Health declarations

The Centers for Disease Control and Prevention (CDC) require all dogs entering the U.S., except those arriving from certain rabies-free countries, to be immunized against rabies.

Vaccinations must be completed at least 30 days before arrival in the U.S.

Since puppies cannot be vaccinated against rabies before 3 months of age, puppies under 4 months old will not be admitted into the U.S. unless they are arriving from a rabies-free country.

Each dog entering the U.S. must be accompanied by a valid certificate of rabies vaccination, signed by a licensed veterinarian and including the following information:

  • Name and address of the dog’s owner
  • Identifying information for the dog, including breed, sex, age, color and markings
  • Date of vaccination and the name of the vaccine used
  • Date when the vaccination expires. If no expiration date is stated, the vaccination must have been completed within 12 months before arrival in the U.S.

Visit the CDC website for more information.

Cats are not required to have proof of rabies vaccination for importation into the U.S; however, some states require vaccination of cats for rabies, so it is a good idea to check with state and local health authorities at your final destination.

Restrictions based on aircraft

You should note that there are some restrictions for specific types of aircraft that you’ll be flying on.

Keep in mind that many routes are served by different types of aircraft so you’ll always need to check and see exactly what type of aircraft you’re flying on.

You can do this be utilizing Google Flights or you can simply check on the United website.

Here are the restrictions:

  • In-cabin travel for pets is booked on a space-available basis.

    • A customer traveling with an in-cabin pet in United Economy on Boeing 757-200 aircraft will need to be seated in a window seat due to limited storage space under aisle and middle seats.

United Service animals

United Airlines has several different types of classifications for service animals and they have different regulations depending on the type of service animal.

Trained service animals

Trained service animals are animals that receive specific training to perform life functions for individuals with disabilities, such as:

  • Visual impairments
  • Deafness
  • Seizures
  • Mobility limitations.

Trained service animals are accepted in cabin for qualified individuals with a disability.

The service animal should sit in the floor space in front of the customer’s assigned seat but cannot protrude into the aisles. Customers may use an approved in-cabin kennel for smaller animals provided its use meets stowage requirements.

Exit row seating is prohibited.

Note that documentation may be required for an animal traveling to international destinations.

Emotional support animals and psychiatric service animals

Emotional support animals and psychiatric service animals that provide emotional, psychiatric or cognitive support for individuals with disabilities, but may or may not have task-specific training with respect to a disability.

Emotional support and psychiatric service animals are also accepted in cabin for qualified individuals with a disability if certain information and documentation are provided in advance of travel.

With prior documentation and clearance a customer may travel with no more than one emotional support animal.

Additional documentation beyond United’s requirements may also be required for an animal traveling to an international destination, Hawaii and other locations.

Customers traveling with an emotional support animal or a psychiatric service animal must provide the required documentation at least 48 hours before the customer’s flight by email ([email protected]).

Service animals in training

Animal trainers are permitted to bring one service animal that is training to assist disabled passengers onboard free of charge. These service animals must not occupy a seat. Trainers transporting service animals in the ordinary course of business or service animals who are not in training must check these animals.

Therapy animals

Therapy animals, which are pets that have been trained and registered by a therapy organization in order to visit nursing homes, hospitals, schools and other facilities, are not considered to be service animals.

When traveling with a therapy animal, standard pet-related regulations and restrictions will apply.

Is United Airlines safe for pets?

You might be wondering if it’s even safe to transfer your pet on United Airlines.

According to the DOT, United had the most animal deaths of all U.S. airlines in 2017 for the third year in a row on scheduled domestic or international passenger flights.

United had a total 18 deaths of animals in 2017, which amounts to 2.4 animal incidents per 10,000 animals transported in 2017. Delta Air Lines had 1 animal death in 2017 and American Airlines had 2 deaths of animals in 2017.

Since United has the wort track record in recent memory, I’d personally try to avoid transporting my furry friends with them in all honesty. But just in case you can’t avoid it, the odds are still very low that there will be an incident since we’re talking about 2.4 animal incidents per 10,000 transported animals.

Still, even with those odds some advise against transporting your animals in the cargo hold.

The Humane Society of the United States “strongly discourages” having your pet travel by air in the cargo hold of a plane, since the experience can be so stressful.
