To fly with a service dog on American Airlines, you complete the U.S. Department of Transportation’s Service Animal Air Transportation Form and upload it through American’s service animal portal at least 48 hours before departure. That single two-page federal form covers the dog’s description, rabies vaccination, training, tasks, and behavior. Once American reviews and approves it, your dog flies in the cabin at no charge, and you receive a Service Animal ID you can reuse on future bookings until the rabies vaccination expires.
Who the Form Is For
Federal aviation rules define a service animal as a dog, of any breed, individually trained to do work or perform tasks for a person with a physical, sensory, psychiatric, intellectual, or other mental disability. Guiding a blind handler, alerting to sounds, interrupting a psychiatric episode, or providing physical stability all count. A dog whose only role is emotional comfort does not.
American follows this definition exactly. Emotional support animals, comfort animals, and service dogs still in training do not qualify and must travel as pets, with the usual pet fees and carrier rules. You may bring up to two service dogs, but each needs its own form and both must fit in your foot space or on your lap without blocking the aisle.
Filling Out the DOT Service Animal Air Transportation Form
The form is a federal document. Blank fields or inconsistent entries can delay approval or cost you boarding at the gate, so work through it carefully.
Your Information and the Dog’s Description
The top of the form asks for your name, the dog’s name, and a basic physical description: breed, weight, and color. Gate agents use this to confirm the dog in front of them matches the approved paperwork.
Rabies Vaccination
Enter the name and phone number of the veterinarian who administered the rabies vaccination, plus the date it expires. If the vaccination is expired on your travel date, the airline can deny boarding. Copy the expiration date directly from the vet’s certificate. A mismatch between the form and the certificate is one of the most common reasons a submission gets flagged.
Trainer and Task Description
List the name and phone number of the person or organization that trained the dog. Self-training is a valid entry; no professional certification is required. Then describe the specific tasks the dog performs for your disability. Be concrete. “Retrieves dropped items” or “alerts handler to oncoming seizures” tells the reviewer far more than “provides assistance.” The airline is confirming the dog does trained work, not that it simply accompanies you.
Behavior Attestation
Your signature attests that the dog is housebroken and will not behave aggressively, meaning no biting, lunging, barking at other passengers, or relieving itself in the cabin or gate area. You also confirm the dog will stay harnessed, leashed, or tethered at all times in the airport and on the aircraft.
The Federal False-Statement Warning
The bottom of the form carries a warning under 18 U.S.C. § 1001. Knowingly making false statements on this document is a federal crime punishable by a fine and up to five years in prison. The warning is printed on the DOT form itself, not added by the airline, and it applies to anyone who signs.
Submitting the Form to American Airlines
American has a dedicated online submission portal for service animal forms, separate from the general Manage Trips page. You reach it through the service animal page under “Special Assistance” in the Travel Information menu. The portal accepts the completed DOT form and, if applicable, the relief attestation form for long flights.
Submit at least 48 hours before your scheduled departure if you booked more than 48 hours out. If you purchased your ticket inside that 48-hour window, the airline must let you present the completed form at the departure gate on the day of travel.
After review, American emails you a Service Animal ID, or SVAN ID. The ID is tied to that specific dog and expires when the rabies vaccination expires. On later bookings, enter the SVAN ID during reservation and skip resubmitting the form, as long as the vaccination is still current. The DOT also limits airlines to requiring the form once per trip, and a round-trip counts as one trip, so you should not need to resubmit for your return flight.
The Second Form for Flights of Eight Hours or More
For any scheduled flight of eight hours or longer, American requires a second DOT document: the Service Animal Relief Attestation Form. On it, you confirm either that the dog will not need to relieve itself during the flight, or that it can do so in a sanitary way, such as using a dog diaper, and you describe the method.
Submit this form alongside the main one through the same portal. If you booked inside 48 hours, bring both completed forms to the gate.
International Trips Need More Than the DOT Form
Flying internationally layers additional paperwork on top of the DOT form. What you need depends on your destination and where the dog has been in the six months before travel.
Entering the United States
Every dog entering the U.S. by air needs a completed CDC Dog Import Form, whether or not it is a service animal. Show the form receipt to the airline before boarding and to U.S. Customs and Border Protection on arrival. If you select “Service animal” on the CDC form, the dog must be traveling with the person it is trained to assist. The receipt is valid for six months and covers multiple entries from the same country. Dogs arriving from countries the CDC classifies as high-risk for rabies face additional vaccination and microchip requirements.
Hawaii
Hawaii runs its own quarantine and vaccination program for all incoming dogs. Service dogs may fly in the cabin to and from every Hawaiian island, but you have to satisfy both American’s documentation and Hawaii’s state rules. Bring all documentation to check-in so the airline can verify both sets.
London Heathrow
Dogs traveling to London Heathrow need advance approval from the Heathrow Animal Reception Centre. Notify HARC by email at least seven days before the flight. If approved, HARC issues a letter you print and present at check-in. Dogs that do not meet HARC’s criteria for assistance animals are subject to a £410 fee.
Partner and Codeshare Flights
If any segment of your itinerary is operated by a partner airline, contact that carrier directly. Each airline has its own service animal forms and policies, and American’s approval does not automatically transfer to codeshare segments.
When American Can Deny Boarding
Airlines are not required to accept every dog presented as a service animal. Under 14 CFR 382.79, a carrier may deny transport if the dog poses a direct threat to health or safety, causes a significant disruption in the cabin or gate area, or violates the health requirements of a U.S. territory or foreign country. Failing to provide the completed DOT form on request is also grounds for denial.
Disruptive behavior is the most common trigger. A dog that barks or growls repeatedly at other passengers, runs freely around the gate area, jumps on people, or relieves itself in the cabin shows it has not been trained for public settings. The airline can then reclassify the animal as a pet, charge a pet fee, require a carrier, or refuse transport.
If you believe American wrongly denied your service dog, ask for a Complaints Resolution Official at the airport. Every airline must have one available, in person or by phone, at no cost during operating hours. Formal complaints go through the DOT’s online aviation consumer complaint portal.
Where to Download the Forms
Both DOT forms are free PDFs. The Service Animal Air Transportation Form and the Service Animal Relief Attestation Form are posted on the DOT’s aviation consumer protection page and on American’s service animal page. Download and complete them before opening the submission portal. Having the vet’s phone number and the exact vaccination expiration date in front of you makes the upload straightforward.
