The DOT Service Animal Air Transportation Form is a federal document you must complete and give to your airline before flying with a service dog on any U.S. carrier or any foreign carrier serving a U.S. airport. It attests, under penalty of federal law, that your dog is healthy, vaccinated, trained to perform a task related to your disability, and trained to behave in public. Falsifying any part of it can carry fines and up to five years in prison.
The form is a PDF on the Department of Transportation’s website, and most airline accessibility pages link straight to it. One form per dog. Airlines can cap you at two service dogs per trip.
Who Qualifies to Use the Form
Under the Air Carrier Access Act, a service animal is a dog, of any breed, individually trained to do work or perform a task for a person with a physical, sensory, psychiatric, intellectual, or other mental disability. That definition is the gate. Cats, birds, miniature horses, and every other species fall outside it. So do emotional support animals, comfort animals, companionship animals, and dogs still in training. Airlines are not required to transport any of them as service animals, though some accept them as pets under separate policies and fees.
Psychiatric service dogs count the same as any other service dog. A dog trained to interrupt a panic attack or provide deep-pressure therapy gets identical treatment, with no extra paperwork and no additional screening based on the disability being psychiatric.
What You’re Signing
The form runs through five areas, and every field has to be filled in. An incomplete form gives the airline grounds to delay or deny boarding.
Handler Information
Your full name, phone number, and email address. You sign an attestation that a service animal is required to accompany you, or the passenger with a disability you’re traveling with, in the aircraft cabin.
Animal Health
The dog’s name, a physical description including weight and color, and an attestation that the animal is free of fleas, ticks, and communicable diseases. You confirm the dog is vaccinated for rabies, list the expiration date of that vaccination, and give the name and phone number of the veterinarian who administered it. The form asks for a phone number the airline can call to verify, not a mailing address.
Task Training and Behavior Training
These are two separate attestations. In the task training section, you confirm the dog has been individually trained to perform a specific task tied to your disability, and you list the trainer or training organization with a phone number. Owner-trained your dog? Enter your own name. In the behavior training section, you separately attest that the dog has been trained to behave in a public setting, again with trainer contact information.
You also attest that, to the best of your knowledge, the dog has not behaved aggressively or caused serious injury to another person or animal. If you can’t make that attestation cleanly, the form gives you space to explain.
Other Assurances and Signature
By signing, you acknowledge three things. The dog must be harnessed, leashed, or tethered at all times in the airport and on the aircraft. If the dog damages airline property, the carrier can charge you on the same terms as any other passenger. And you’re signing an official federal document; knowingly false statements expose you to fines and criminal penalties.
The Relief Attestation Form for Flights of 8 Hours or More
If any segment of your itinerary is scheduled for eight hours or longer, the airline can require a second, shorter form: the U.S. DOT Service Animal Relief Attestation Form. You check one or both boxes confirming that the dog will not need to relieve itself during the flight, or that it can do so on the aircraft without creating a health or sanitation problem. If you check the second box, you describe your method, such as a dog diaper. No vet certification is needed. It’s your own attestation.
When and How to Submit It
Airlines can require the completed form at least 48 hours before your first scheduled departure, but only if you booked more than 48 hours out. Book inside that two-day window and the airline cannot demand advance notice, though it can require you to complete and hand over the form at the departure gate. The same 48-hour rule applies to the relief form when it’s needed.
Most carriers accept the form through a dedicated online accessibility portal, where you upload a scanned PDF or a clear photo linked to your reservation. Some also accept submissions through the airline’s mobile app or a disability services email address. Channels vary by carrier, so check the airline’s accessibility page rather than assume. Once processed, you’ll usually get an email confirmation or a notation on your boarding pass showing the service animal has been pre-approved.
Airlines cannot require documentation beyond the two DOT forms, unless a federal agency, a U.S. territory, or a foreign government’s laws impose additional entry requirements for the animal. If you’re flying internationally, that last piece is on you to research: import permits, additional health certificates, or quarantine documentation for the destination country.
On Flight Day
Bring a copy of the signed form, paper or digital, even if you uploaded it days ago. Gate agents and check-in staff may ask to see it. They’ll also be watching your dog. A properly trained service dog stays calm at your side and doesn’t lunge, bark repeatedly, or show aggression toward other passengers or animals.
Your dog must be harnessed, leashed, or tethered at all times in airline-controlled areas and on the plane. It rides on the floor at your feet. It cannot occupy a seat, block the aisle, or obstruct an emergency exit. Airlines do not have to upgrade you to a larger seat or different cabin to make room.
If the dog is too large to fit safely in your foot space without blocking required clearance, the airline can deny cabin transport. In that case, the carrier must offer either cargo-hold transport at no charge or a rebooking on a later flight with space, subject to FAA safety rules.
When Boarding Can Still Be Refused
A completed form is not a guarantee. An airline can still refuse a service dog that poses a direct threat to health or safety, is too large for safe cabin accommodation, or behaves in ways showing it hasn’t been properly trained. Running loose in the gate area, barking or growling repeatedly, biting or jumping on people, or relieving itself in the cabin or gate area all qualify. If the dog’s behavior contradicts what you attested to, the airline can treat it as a pet, charge a pet fee, require a carrier, or deny transport outright. Crew members can reassess behavior throughout the flight, not just at boarding.
If the Airline Won’t Comply
If an airline refuses a properly documented service dog, demands paperwork beyond the DOT forms, or charges a fee for a legitimate service animal, ask to speak with a Complaints Resolution Official. Every airline is required to have a CRO available in person or by phone during operating hours, at no cost to you. The CRO is the airline’s in-house disability accommodation expert and can often resolve disputes on the spot.
If that doesn’t fix it, file a formal complaint through the Department of Transportation’s online consumer complaint portal. DOT investigates Air Carrier Access Act violations and can take enforcement action against carriers that fail to comply.
