Traveling With Pets on a Plane

What should you know when deciding to travel with your family pet on a plane?

There are various rules when it comes to traveling with pets on a plane. Some restrict the number of pets you can fly with to two and the size of the kennels may be specific. Check-in and reservation requirements vary, some have restricted breeds, and other limitations that make prior research a very important factor when traveling with pets on a plane.


American Airlines

One of the first things to consider when traveling with pets on a plane is their age and breed. American Airlines restricts dogs and cats under 8 weeks of age from traveling within the U.S. Dogs and cats with brachycephaly or snub-nosed dogs are not accepted for travel with AA. Common breeds that fall into this category are Boston Terrier, Boxer, Pug, Shih Tzu, Lhasa Apso, Burmese and Persian cats, as well as Himalayan cats. AA does not require a health certificate for pets to fly domestically, however, some states do. Contact American Airlines about health documentation required for travel to Hawaii and international destinations.


Destination time restrictions are limited to 11 hours and 30 minutes, including the time needed to go through customs. On AA flights, passengers can bring one kennel as a carry-on bag if:

  • They pay the carry-on pet charge
  • The pet stays in the kennel under the seat for the entire duration of the flight


Kennel requirements state the pet must be able to stand and turn in the kennel as well as lie down without touching any sides or top of the container. Soft-sided kennels must be made of water-repellant material and have nylon breathable ventilation areas. Hardshell kennels must fit underneath the seat in front of the passenger without exceeding the aircraft dimensions. Contact AA Customer Services at 800-433-7300 to secure travel reservations for your pet.


Southwest Airlines

Southwest Airlines’ website provides slightly more lenient qualifications when it comes to traveling with pets on a plane. While accepting only small dogs and cats, they do not list age or breed restrictions. They also do not require a health certificate or any other documentation from a veterinarian for a pet to travel. Carriers can be soft or hard-sided, must be leak-proof, well ventilated, and small enough to be stowed away under the seat in front of them. Travelers are subject to a $95 Pet Fare each way per pet carrier (limit 1 pet carrier per person, up to two pets of the same species per carrier). Reservations are required in advance by calling 1-800-I-FLY-SWA.

Southwest Airlines Pet Carrier can be purchased for $58.00 and is an approved carrier meeting all requirements per the airline.


Delta Airlines

Small dogs, cats, and birds are allowed to travel in the cabin on Delta flights for an additional one-way fee. Traveling from U.S./Canada/Puerto Rico requires a $125 USD checked pet fee each way. U.S. Virgin Islands/ Puerto Rico increases to $200 each way, while Brazil decreases to $75. Delta does not require a health certificate for pets traveling in the cabin, however again, pet health certificate requirements are determined by each state. Pets again must fit in a small, ventilated carrier that fits under the passenger’s seat in front of them. Delta requires pets to be at least 10 weeks of age for domestic travel and 16 weeks for international. One pet is permitted per kennel with the exception of an un-weaned litter 10 weeks to 6 months of age. A secondary exception is two pets of the same breed and size between 10 weeks and 6 months in one kennel with adequate room for mobility.  Call Delta in advance at 800-221-1212 to schedule arrangements for bringing your pet aboard.


United Airlines

United Airlines allows domesticated travel companions on their airlines limited to dogs, cats, rabbits, and birds (excluding cockatoos). Puppies and kittens must be 16 weeks of age and must fit in a carrier that remains in the floor space below the passenger’s feet at all times. United allows for only one pet per kennel with the exception of birds. Each dog entering the U.S. from a foreign country must have a valid certificate of rabies vaccination, signed by a licensed vet and include specific information. Cats are not required to have the same proof of vaccination however it is required by some states. Local health authorities at the final destination should be contacted to confirm the requirements. Contact United Customer Services at 1-800-UNITED-1 for more information.
