American Airlines Pet Policy

The American Airlines pet policy is as follows:
Starting February 1, 2021, only trained service animals can fly in the cabin and you’ll need to complete and submit the U.S. Department of Transportation (DOT) Service Animal Air Transportation form before your trip. If you’re traveling with an animal that doesn’t qualify as trained service animal, it may be transported as a pet.
Due to increased flight changes, checked pet service has been suspended.
Carry-on pets and service animals may fly in the cabin if they meet the requirements. If your pet is too large to fit in the cabin, please contact American Airlines Cargo.
Pets in the cabin are accepted on most flights up to 11 hours and 30 minutes or flights to / from: within the 48 contiguous United States, Alaska, Puerto Rico, St. Thomas and St. Croix; the U.S. and Canada; Mexico; and Central America.
On American flights you can bring 1 kennel as your carry-on bag.
Due to the lack of underseat storage space, carry-on pets are not permitted in First or Business on certain flights.
American Airlines Cargo will no longer accept sedated or tranquilized cats or dogs for transport.
International kennel requirements – “100 series” kennels will no longer be accepted for cats and dogs traveling internationally.
Dogs traveling to the UK – During the kennel screening process, a photo will be taken to ensure that the dog is able to sit, stand and turn around without touching the top or sides of the kennel.
Taking a pet to a foreign country involves preparation and planning far in advance of your departure date. Requirements for pet travel to a foreign country are set by the destination country. If you are you traveling to another country and bringing along your pet you’ll need to meet the animal health requirements of the country you are visiting.
