Delta Airlines Service Animal Rules: Forms, Fees, and What Delta Allows

A Delta Airlines service animal is a dog, regardless of breed, that is individually trained to do work or perform tasks for a person with a disability. As of September 2026, Delta Air Lines accepts up to two trained service dogs in the cabin at no transport fee and does not treat emotional support animals as service animals. Handlers file a U.S. Department of Transportation form, plus a relief attestation when a flight is eight hours or longer.

Rules below come from Delta Air Lines and the United States Department of Transportation (DOT). This is not legal advice. Last updated September 21, 2026, by Animal Passport.

What counts as a Delta Airlines service animal?

Under the Air Carrier Access Act (ACAA), 14 CFR 382.3 defines a service animal as a dog, regardless of breed or type, individually trained to do work or perform tasks for a person with a disability, including a psychiatric disability. Other species, emotional support animals, comfort animals, companionship animals, and service animals in training are not service animals. The Federal Register published that definition on December 10, 2020, and it took effect January 11, 2021.

Delta’s trained-service-animal page matches that line. The dog must be fully trained to assist a person with a disability, current on vaccinations, able to fit in the foot space of the customer’s seat without entering the aisle or another passenger’s space, and must not show aggressive or inappropriate behavior. Delta says emotional support animals are not recognized as service animals and points those travelers to the pet rules.

A psychiatric service dog qualifies only when it is task-trained. Comfort without a trained task is an emotional support animal, which the December 10, 2020 rule let airlines treat as a pet. Delta’s current page follows that split.

Service dog, emotional support animal, cabin pet, or Animal Passport

A search for a Delta Airlines service animal often mixes four different records. Only a task-trained dog uses Delta’s service-animal path.

Animal Passport identifies livestock with a phone-captured nose print, treated as unique like a fingerprint. The record can bind the owner, breed, an estimated age from a dental photo with a confidence score, a body condition score from 1 to 5 on a side-profile photo, and vaccination history. In August 2025 it was used in livestock flood rescue in Pakistan after paper tags washed away. It is not a DOT form and does not admit a dog to a Delta cabin. Related notes are on the Animal Passport blog.

Which forms does Delta ask for?

14 CFR 382.75 allows a carrier to require a current U.S. Department of Transportation Service Animal Air Transportation Form as a condition of cabin travel. Current means the form was completed on or after the date the passenger bought the ticket. On a segment scheduled to take eight hours or more, the carrier may also require a current DOT Service Animal Relief Attestation Form, stating the animal will not need to relieve itself or can do so without a health or sanitation problem.

Delta’s page says the DOT requires the air-travel form for every service animal and the relief attestation on flights of eight hours or more. The regulation only permits a carrier to require the forms; Delta chooses to require them. Send the forms with Delta’s service request, and check the trained-service-animal box, at least 48 hours before departure when you booked earlier than that.

14 CFR 382.75(g) limits that deadline. If the reservation was made more than 48 hours before the first scheduled departure, the airline may require up to 48 hours’ notice. If it was made later, the airline may not require advance notice and may collect the forms at the gate. If a passenger misses a lawful deadline, 14 CFR 382.75(h) still requires the accommodation when reasonable efforts can provide it without delaying the flight. Under 14 CFR 382.75(c), the airline may not demand other service-animal documents except those required by a U.S. federal agency, a U.S. territory, or a foreign jurisdiction. Delta says a National Service Animal Registry membership does not replace its rules. Its accessibility line is 404-209-3434, or 711 for relay.

You may check in on the Fly Delta app or at the airport. Delta does not require a counter visit solely because of the service animal, but it recommends keeping the DOT form available. 14 CFR 382.76 bars the airline from forcing an airport check-in, instead of the online check-in offered to other passengers, only because you are traveling with a service animal.

Steps before departure

1. Confirm the animal is a task-trained dog, not an emotional support animal and, in most cases, not a dog still in training.
2. Buy the ticket first, then complete the DOT Service Animal Air Transportation Form so it is current under 14 CFR 382.75.
3. Add the DOT Service Animal Relief Attestation Form if any segment is scheduled for eight hours or more.
4. Send the forms to Delta at least 48 hours ahead when the booking was made earlier, or bring them to the gate if you booked inside that window.
5. Choose a seat that is not an exit row. The dog rides on your lap or in the foot space in front of you.
6. For a second dog, file a separate DOT form. Delta’s maximum is two service animals, and both must fit without blocking the aisle.

Fees compared with cabin pets

14 CFR 382.78 says a carrier generally cannot charge a passenger with a disability for transporting a service animal, or for other services that part requires. It may charge for damage the animal causes only when it normally charges passengers without disabilities for similar damage. Delta states that it does not charge fees for trained service animals or their assistive devices, even if checked. The kennel, occupied or empty, is an assistive device and is exempt from baggage fees. Delta also says essential items such as a bed or food travel free, and the service animal does not count against the carry-on allowance.

Cabin pets are priced separately. Delta’s pet page lists an each-way fee of $95 USD or CAD for tickets issued before April 8, 2025, and $150 USD or CAD for tickets issued on or after April 8, 2025, for the United States, Canada, Puerto Rico, and the U.S. Virgin Islands. The international fee is $200 USD, CAD, or EUR. For Brazil, Delta lists $75 before April 8, 2025, and $200 USD on or after that date. Delta says CAD is charged when exiting Canada and EUR when exiting Europe, under the contract of carriage in effect at ticket issuance. Those amounts are pet fees, not the service-animal transport charge Delta says it does not collect.

If one seat cannot hold you and the dog without an obstruction, Delta says you may buy an extra ticket, purchased with the original so the fare matches, for the dog’s floor space, or check the dog below the cabin at no extra charge. 14 CFR 382.77 requires lap or foot-space placement unless safety rules or another passenger’s space would be violated. Before a refusal, the airline must offer another seat in the same class of service if one can fit the dog. If the cabin cannot take the dog on that flight, it must offer free cargo-hold transport or a later flight when space and safety rules allow.

Age, vaccines, behavior, and breed

Delta requires service animals to be fully vaccinated and at least four months old. A puppy may receive a rabies vaccine at three months, then wait 30 days so the vaccine can take effect before flying at four months. If a dog older than 15 months had a rabies vaccination that has since expired, Delta says the dog may fly immediately after a booster, with no 30-day wait. Health and vaccine status are attested on the DOT form.

Entry into the United States can impose a higher age. Delta’s pet page says the U.S. Centers for Disease Control and Prevention requires every dog traveling to the United States to appear healthy, be microchipped, be at least six months old, and carry a receipt for a CDC Dog Import Form. Delta adds that more documents may be required based on where the rabies vaccine was given and whether the dog was in a high-risk rabies country in the prior six months. That border summary is not the same as Delta’s four-month cabin minimum. On a trip into the United States, the stricter entry condition controls at the border, including for a service dog.

Delta will refuse the dog if it growls, bites, lunges, jumps on people, relieves itself outside an approved relief area, barks excessively except for the handler’s needs, or eats from a tray table. 14 CFR 382.73 allows only two questions: whether the animal is required because of a disability, and what task it performs. Staff may not ask about the disability or demand a demonstration. The dog must be harnessed, leashed, or tethered on the aircraft and in airport areas the carrier controls.

Breed alone is not a lawful refusal. 14 CFR 382.72 bars denial based on breed or type, or because the dog may annoy people. 14 CFR 382.79 still allows refusal after an individualized assessment, independent of breed, for a direct threat, serious disruption, a U.S. or foreign health or safety violation, or missing current DOT forms. The reason must be in writing at the airport or within 10 calendar days. Delta’s current page lists no banned breed. An older Delta page still describes a July 10, 2018 limit on emotional support animals and pit bull-type dogs. That page conflicts with the January 11, 2021 rule. Use the current Delta page and 14 CFR Part 382.

Training dogs, clubs, and the flight itself

DOT does not treat a service animal in training as a service animal. Delta says the same in most cases, with one stated exception: a dog in training may travel with a professional trainer who is taking it to the owner. That is not a general right to bring a dog that is still learning tasks.

Delta uses the same behavior rules in a Sky Club as on the aircraft. Agents can point you to an airport relief area. You may pre-board or board with your zone. The dog stays on your lap or in your foot space, not in a passenger seat or an exit row. Delta reassigns an exit-row seat at the gate. Pet bans on bulkhead, flat-bed, and Delta One seats are pet rules. Delta’s pet table says those cabin limits exclude service animals, so do not apply a pet-seat ban to a task-trained dog without checking the service-animal page.

International flights and partner airlines

Delta says some countries bar the entry or transit of animals and tells travelers to check the destination consulate and Delta’s international animal guidance. 14 CFR 382.79 lets the airline refuse the dog when carriage would violate a U.S. federal, U.S. territorial, or foreign safety or health requirement. Foreign health papers can therefore still be required under 14 CFR 382.75(c) even though the airline cannot add its own extra service-animal forms.

Delta’s pet page bars ordinary cabin pets on routes that include Australia, Barbados, Hawaii, Hong Kong, Iceland, Jamaica, New Zealand, South Africa, the United Kingdom, the United Arab Emirates, and pets originating in Brazil, Colombia, or the Dominican Republic. That list is a pet rule, not a service-dog ban on Delta’s service-animal page. Destination law can still stop the dog. Delta points travelers to the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) for country entry documents, which are separate from the DOT form.

On a Delta-marketed flight flown by a partner, check the operating airline. The December 10, 2020 final rule says a U.S. carrier in a code-share must ensure the foreign carrier follows the service-animal provisions when the passenger travels under the U.S. carrier’s code.

A livestock passport is not this form

A government veterinary travel paper, where a country issues one, is a border health record. Delta’s form is a DOT attestation under the Air Carrier Access Act. Animal Passport is neither: it does not diagnose disease, and it is not a government travel credential. A service dog on Delta still needs the DOT form and any entry papers the route requires.

As of September 2026, a Delta Airlines service animal is a task-trained dog carried without a pet fee when the DOT forms are complete and the dog stays under control. An emotional support animal travels as a pet. A livestock biometric record is not a boarding document.

Frequently asked questions

Does Delta Air Lines allow service animals?

Yes. As of September 2026, Delta accepts up to two dogs trained to assist a person with a disability when the DOT forms are filed and the dog fits and behaves. Emotional support animals are not service animals on Delta.

Can Delta refuse a service dog because of breed?

14 CFR 382.72 prohibits refusal based on breed or type. Delta’s current page lists no banned breed. The airline may still refuse a dog after an individual assessment of threat, disruption, or a legal entry barrier, and it must give the reason in writing.

How early must the Delta service animal form be sent?

Bookings made more than 48 hours ahead should include the forms at least 48 hours before departure. Bookings made later cannot be forced into advance notice; Delta may take the forms at the gate, under 14 CFR 382.75.

Is Animal Passport accepted as a Delta service animal document?

No. Animal Passport is a phone-based livestock identity record using a muzzle biometric. It is not the DOT form and not a government travel credential for a Delta flight.
