Frontier Service Animal Form: How to Complete and Submit the DOT Form in 2026

The Frontier service animal form is the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form, a federal attestation that Frontier Airlines requires for every trained service dog flying in the cabin. As of October 2026, Frontier says you must submit it at least 48 hours before departure if you booked earlier than that. If you booked within 48 hours, you present it at the airport. Only task-trained dogs qualify, and Frontier does not accept emotional support animals.

This guide explains what the form asks, how to upload or mail it to Frontier, the deadlines in the federal rule, and the places where Frontier's own web pages disagree with each other. It is published by Animal Passport, which builds biometric identity records for livestock. We explain at the end why that product is a different thing from an airline service animal form.

What is the Frontier service animal form?

Frontier does not use its own service animal form. Its Special Services page (Frontier Airlines, 2026) says passengers flying with a service dog "must complete and submit the DOT's Service Animal Air Transportation Form, attesting to the dog's health, behavior, and training." The same form is used by other U.S. airlines because DOT wrote it.

The legal basis is the Air Carrier Access Act (ACAA) rule that DOT published in the Federal Register on December 10, 2020. The rule took effect on January 11, 2021, and it allows airlines to require the DOT form as a condition of carrying a service animal in the cabin. The current version of the form was updated in September 2024. It carries Office of Management and Budget (OMB) control number 2105-0576 with an expiration date of 09/30/2027. DOT estimates it takes about 20 minutes to complete.

The form opens with a warning that knowingly making false statements on it to obtain disability accommodations is a federal crime under 18 U.S.C. § 1001.

Who needs the Frontier service animal form?

You need the form if you, or a passenger with a disability traveling with you, will bring a trained service dog into the cabin. Frontier's Special Services page (2026) sets out these rules:

• Dogs only. Frontier accepts only dogs as trained service animals in the cabin.
• Psychiatric service dogs count. Frontier accepts fully trained psychiatric service dogs.
• Two-dog limit. Each passenger with a disability may travel with up to two service animals, which matches the cap DOT allowed in its 2020 rule.
• No emotional support animals. Frontier stopped accepting emotional support animals on February 1, 2021. Comfort and companionship animals are also not treated as service animals.
• No dogs in training. Frontier does not accept service animals in training.
• Age. Frontier does not accept service animals younger than 4 months.
• Control. The dog must be harnessed, leashed, or tethered at all times in the airport and on the aircraft.

DOT's definition, repeated in the form's instructions under 14 CFR 382.3, is a dog "regardless of breed or type" that is individually trained to do work or perform tasks for a person with a physical, sensory, psychiatric, intellectual, or other mental disability.

What the DOT Service Animal Air Transportation Form asks

The form has five sections. You fill in all of them yourself. No veterinarian or trainer signature is required, but the airline may phone the people you list.

Section A: Service Animal Handler Information

Your full name, phone number, and email address, and a checkbox attesting that a service animal is required. The handler is the passenger with a disability or a third party traveling with them, such as the parent of a minor child or a caretaker.

Section B: Service Animal Identification and Health Information

The dog's name and a description that includes its weight and color. DOT's instructions say the airline may use this description to confirm the dog's identity at the airport. You attest that the dog has no fleas, ticks, or disease that would endanger people or animals and that it is vaccinated for rabies. You also enter the rabies vaccination expiry date and your veterinarian's name and phone number. The veterinarian does not sign.

Section C: Service Animal Task Training

You attest that the dog is individually trained to perform a task related to a disability, and you list the trainer or training organization with a phone number. If you trained the dog yourself, you may list your own details. DOT says no training certificate is required.

Section D: Service Animal Behavior Training

You attest that the dog is trained to behave in public, and you list the behavior trainer. You also confirm that you understand a dog that shows it has not been trained to behave can be treated as a pet. That means a pet fee and a carrier, or a refusal to carry it. Finally, you attest that the dog has not behaved aggressively or seriously injured a person or animal. If you cannot make that statement, you explain why in the space provided.

Section E: Other Assurances

You confirm that the dog stays harnessed, leashed, or tethered, and that you may be charged for damage the dog causes if Frontier would charge other passengers for similar damage. You also confirm that you are signing an official DOT document. Then you sign and date the form.

How to submit the Frontier service animal form: step by step

1. Book your flight first. Under 14 CFR 382.75, a form is "current" only if it was completed on or after the date you bought your ticket. A form you filled in before booking may be rejected.
2. Add the service animal request. Frontier says you can select a trained service animal request while booking. For an existing reservation, you can add it online through Manage Trip.
3. Download the DOT form from the link on Frontier's Special Services page.
4. Type your answers into the PDF if you can. Frontier's Service Animal Documentation portal says a typed PDF gets an automatic approval or decline. A handwritten form goes to manual review, which can take up to 7 days.
5. Upload the form through the portal with your phone number, address, Frontier flight number, confirmation code, and date of first travel. You can also mail it to Attention Frontier Customer Care, 4545 Airport Way, Denver, CO 80239. Leave plenty of time if you mail it.
6. Keep a copy with you. Frontier says staff may ask to see the form at the airport or on board.

Deadlines: the 48-hour rule and last-minute bookings

As of October 2026, Frontier's deadline follows the federal rule:

• Booked more than 48 hours before departure: submit the completed form no later than 48 hours before travel.
• Booked less than 48 hours before departure: you cannot be required to give advance notice. You bring the completed form on the day of travel.

Frontier's pages differ on where the short-notice form goes. The Special Services page says to give it "in person to a Customer Service Agent upon arrival at the airport." The documentation portal says to present it "at the departure gate." The federal regulation, 14 CFR 382.75(g)(3), lets airlines require it at the departure gate. To be safe, carry a printed copy and show it at check-in and at the gate if asked.

Two more federal protections help when plans change. First, DOT's form instructions say an airline may require the form once per trip, so a round-trip ticket counts as one trip. Second, under 14 CFR 382.75(h), if you miss the advance deadline the airline must still carry the dog if it can do so with reasonable efforts and without delaying the flight. Do not rely on that as a plan, but it is your right.

DOT also has a separate Service Animal Relief Attestation Form for flight segments of 8 hours or more. Frontier's Special Services page does not mention it and refers only to the Air Transportation Form.

Service dog vs. pet vs. emotional support animal on Frontier

The $149 fee comes from Frontier's Optional Services page (2026). Frontier's pet FAQ sets carrier limits of 18 x 14 x 8 inches for hard-sided carriers and 18 x 14 x 11 inches for soft-sided carriers. The FAQ also says Frontier does not carry pets in the cargo hold and allows only service dogs on international flights.

Frontier's pages also disagree on combining a service dog with a pet. The service animal list on the Special Services page says "only one pet in cabin per person." The pet FAQ says a customer with a trained service dog may also bring one pet in the cabin. If you plan to bring both, confirm with Frontier before you fly.

Flying internationally with a service dog on Frontier

DOT's rule allows airlines to ask for extra documents when a federal agency, a U.S. territory, or a foreign country requires them (14 CFR 382.75(c)). Frontier's Special Services page lists these extra requirements for service dogs on international trips:

• A Centers for Disease Control and Prevention (CDC) Dog Import Form receipt.
• A minimum age of 6 months.
• The dog must look healthy on arrival.
• Proof of a microchip that a universal scanner can read.

Dogs that have been in high-risk countries need more paperwork, including a photo of the dog and government-endorsed veterinary documents. The CDC says (2024) that the requirements depend on where the dog was vaccinated and which countries it has been in during the 6 months before entering the United States. The CDC also says the U.S. Department of Agriculture (USDA) and your destination may have their own rules. Note the difference in ages: Frontier's general minimum age for a service animal is 4 months, but its international rules require 6 months.

At the airport and on board

Frontier says its staff may ask fact-finding questions if your disability is not obvious, such as what task the dog has been trained to do. They may ask again at different points during the trip. On board, the dog must not block the aisle, occupy an empty seat, or crowd a neighbor's seat. Passengers with service animals cannot sit in an emergency exit row. A dog can sit on your lap only if it is no larger than a child under two. A carrier is optional, but if you use one, it goes under the seat in front of you for taxi, takeoff, and landing.

Frontier can deny boarding to a dog that is disruptive or poses a direct threat. Its examples include scratching, excessive whining or barking, growling, biting, lunging, and urinating or defecating in the cabin or gate area.

Common mistakes that delay approval

• Filling in the form before buying the ticket, so it is not "current" under 14 CFR 382.75.
• Entering a rabies expiry date that falls before your return flight.
• Listing an old veterinarian or trainer phone number. DOT says the airline may call to verify, and wrong details cause delays.
• Handwriting the form close to the deadline, when manual review can take up to 7 days.
• Forgetting to bring a copy to the airport.
• Assuming an emotional support animal letter will be accepted. It will not.

How this differs from an Animal Passport record

Searches for "animal passport" often mix up travel documents and identity records, so here is the difference. The DOT Service Animal Air Transportation Form is a federal attestation for one airline trip. Government pet travel schemes, such as EU pet passports, are separate official documents with their own rules. Neither is related to Animal Passport.

Animal Passport is a digital passport for livestock and other animals. It identifies each animal by its muzzle biometrics, because a nose print is unique like a fingerprint. Owners capture photos on a phone, and the record links the owner, breed, estimated age, body condition, and vaccination history. Age is estimated from a dental photo with a confidence score, and body condition is scored from 1 to 5 using a side-profile photo. In August 2025 it was used during livestock flood rescue in Pakistan so farmers could reclaim animals after their paper tags washed away.

Animal Passport is not a government-issued travel document, a DOT form, or a veterinary certificate. Frontier will not accept it in place of the DOT Service Animal Air Transportation Form. For more on animal identity and travel rules, see the Animal Passport blog.
