To fly with a service dog on Frontier, you must submit the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form before your flight. Frontier accepts a trained service animal in the cabin at no charge when the dog is a trained service animal that behaves and can fit at your feet. Frontier no longer recognizes emotional support animals as service animals; under the 2021 DOT rule, an emotional support animal travels as a pet. Complete the DOT form, arrive early, and keep your service animal leashed and under control.
Does Frontier accept service dogs?
Yes. Frontier accepts a trained service animal in the cabin free of charge for a passenger with a disability. Under DOT rules, a service animal is a dog individually trained to do work or perform a task, so Frontier treats a trained service dog as a service animal, not a pet. The service animal must be leashed or harnessed, behave in the airport and on board, and fit within your foot space without blocking the aisle.
The DOT Service Animal form Frontier requires
Before flying, you must complete the DOT Service Animal Air Transportation Form, in which you attest that your service animal is trained, healthy, and will behave. Frontier asks that you submit this form in advance, generally at least 48 hours before departure when you book that far ahead. Submitting the form on time is the single most important step for flying a service animal on Frontier without a delay at the gate.
Emotional support animals on Frontier
Frontier no longer treats an emotional support animal as a service animal. Since the 2021 DOT rule, only a trained service dog qualifies as a service animal in the cabin. An emotional support animal may still travel, but as a pet under Frontier’s pet policy, which means a carrier and a pet fee. If your animal is a trained service dog, it flies free; if it provides comfort only, it flies as a pet.
Behavior and space rules on board
Your service animal must sit at your feet or in your lap if small, stay leashed or tethered, and not occupy a seat or block the aisle. Frontier can treat a service animal that growls, lunges, or relieves itself repeatedly as disruptive. A trained service animal that behaves has full cabin access. You may travel with up to two service animals; each must fit in your own foot space.
Booking and check-in tips
Book early, complete the DOT form as soon as you can, and arrive at the airport with extra time so gate agents can review your paperwork. Bring a leash and a familiar mat, and give your service animal a chance to relieve itself before boarding. Frontier’s disability desk can confirm that your form is on file, which prevents last-minute problems when you fly.
What Frontier can and cannot ask
Frontier may require the DOT form and may ask whether your dog is a trained service animal and what task it performs, mirroring the ADA two-question standard on the ground. Frontier cannot demand proof of the disability, cannot require a health certificate beyond the DOT form’s attestations for domestic flights, and cannot charge a fee for a legitimate service animal.
If Frontier denies your service dog
If a Frontier agent wrongly denies a trained service animal, ask for a Complaints Resolution Official (CRO), a trained employee airlines must provide to resolve disability issues. If the CRO cannot help, you can file a complaint with the DOT after your trip. Keeping your DOT form and booking records makes any dispute over your service animal easier to resolve.
Registering your service dog before you fly
Registration is not required to fly a service animal on Frontier, but many handlers document their service dog with USAR so they can show a verifiable record. A USAR registration provides a digital and printed ID and a scannable QR page. It does not replace the DOT form, which is the document Frontier actually requires.
Which service dogs Frontier accepts
Frontier Airlines accepts service dogs that are individually trained to do work or perform tasks for a passenger with a disability, including psychiatric service dogs. Frontier does not accept an untrained animal, and disruptive behavior at the gate or on the aircraft can cause a service dog to be denied transport. A service dog is accepted when the passenger has completed documentation and the dog behaves; frontier airlines applies the same standard to every service dog it accepts for a flight.
Booking and gate tips for Frontier passengers
Frontier passengers flying with a service dog should submit documentation early, arrive at the gate with time to spare, and be ready to show the completed DOT form. The airline will accommodate a trained service dog on the aircraft at no charge, but passengers who arrive late risk delays. Frontier customers who fly often with a service dog keep the form saved on their phone so any gate agent can confirm the service dog is accepted for transport.
Frontier, the Air Carrier Access Act, and required documentation
Frontier follows the Air Carrier Access Act, the federal rules a federal agency (the Department of Transportation) enforces. Under these federal rules, a service dog must be individually trained to perform tasks that benefit a qualified individual with a physical or mental disability. Frontier requires documentation, and comfort animals and companionship animals are not accepted because they do not perform tasks. A service dog is accepted only when the required documentation is complete and the dog can behave properly in the gate area and on the plane.
Behavior that can lead to denied boarding on Frontier
Disruptive behavior can cause denied boarding for safety reasons. Barking, growling, lunging, urinating, or excessive whining in a public setting signals the dog cannot behave properly, and the flight crew may determine the dog is a direct threat. For these safety reasons, keep the dog under control so other passengers are not disturbed. A trained service dog that stays calm on the aircraft, on the flight, and through landing keeps its access; Frontier customers with a psychiatric service dog should be ready to confirm the dog’s health and control on request.
