Booking and Flying Policies

You must notify Frontier Airlines that you intend to fly with a PSD. Customers can select trained service animal special requests during booking. If a dog does not meet the requirements, it may be eligible to travel as a pet.

If you’re booking a flight, it helps to know Frontier Airlines’ pet policy. Frontier Airlines allows travelers to fly with pets. However, there are certain restrictions on animals permitted in the cabin. Remember that the Air Carrier Amendments Act of 2021 expands provisions prohibiting discrimination against disabled individuals by any air carrier. 

Frontier Airlines Pet Fees

Frontier Airlines charges a one-way, directional fee of $99 for pets. You can pay in advance while booking or during the pet’s check-in.

Frontier Airlines Breed Restrictions

The ACAA prohibits airlines from refusing to transport a service animal based on breed.

Domesticated dogs, cats, rabbits, guinea pigs, hamsters, and small household birds are allowed on domestic flights. Domesticated cats and dogs must be at least eight weeks old.

Frontier Airlines never allows large birds, rodents, beavers, ferrets, reptiles, amphibians, spiders, or insects. Plan to keep your animal in a pet carrier to stay safe throughout the flight.

The maximum size for a pet carrier on Frontier Airlines is 18″ length x 14″ width x 8″ height. It must be large enough for your pet to stand, turn around, and lie in a natural position. And it must fit underneath the seat in front of you.

Certain seats on the plane may not be large enough to fit your animal carrier, but the airline will work with you to ensure you get a seat assignment with plenty of space. In addition to the carrier, you can bring either a personal item or a carry-on bag.
