Frontier Airlines flying with pets

What is Frontier Airlines policy on pet acceptance?

Frontier Airlines accepts pets in the cabin of the aircraft only. Frontier Airlines does not accept pets traveling as checked baggage.

Frontier Airlines accepts pets in the cabin on all domestic flights and international flights to/from Mexico, Costa Rica, and the Dominican Republic.

Which pets are accepted to travel on Frontier Airlines flights?

On domestic flights, domesticated dogs, cats, rabbits, guinea pigs, hamsters, or small household birds are accepted.

On international flights, only domesticated dogs and cats are accepted if required health documents are provided by the passenger.

Pets in the Cabin

Frontier Airlines accepts only 10 pet containers per flight, so you must make advance arrangements by calling Frontier Reservation to ensure availability and reserve space for your pet. Pets can’t be booked online, but the same low fares with no ticketing fee are offered through Frontier Reservations.

When traveling with a pet, you are responsible for making arrangements and assuming full responsibility for complying with any entry requirements (laws, customs and other governmental regulations) of the country, state or territory to which the pet is being transported. While Frontier Airlines does not require a health certificate for pets carried in the cabin traveling within the U.S., the certificate may be required by the state upon arrival.

Required health documents must be provided when traveling to/from a foreign destination. For international travel, a health certificate is required and must include the name and address of the owner, animal species, country of origin/destination, and immunization against rabies within 12 months for adult pets. The immunization must be administered no earlier than 30 days prior to international travel otherwise proof of the prior rabies shot is required. The health certificate must be dated within 10 days of entry into the United States, 5 days of entry into Mexico, 30 days of entry into Puerto Rico, 14 days of entry into Costa Rica, and 15 days of entry into the Dominican Republic. Each country has vaccination requirements beyond rabies:

  • A statement, on the health certificate, indicating that the pet is free from parasites and has been treated for parasite prevention is required for travel to Mexico and the Dominican Republic.
  • Hepatitis, PIP, and leptospirosis vaccinations are recommended.
  • Both a rabies vaccination and a health certificate are required for travel to/from Canada.

Frontier Airlines allows no more than one pet container per passenger. The pet container always counts as either your personal item or carry-on bag. If the pet is taken in place of your personal item, the Carry-on Fee may apply if you also take a carry-on bag.

Your pet must remain in the pet container at all times, so you must be able to soothe your pet without taking him/her out from the pet container. Frontier Airlines recommends that you give your pet food or water within 4 hours of departure.

The pet container must be large enough for your pet to turn around, stand, and lie down in a natural position and must fit underneath the seat in front of you. Seat restrictions apply depending on the aircraft type because certain seats cannot accommodate your pet container. Frontier Airlines only accepts pet containers with the following maximum dimensions: 18” length x 14″ width x 8″ height.


The pet-in-cabin fee of $99 one way will be assessed at check-in or may be paid in advance at the time of booking.

Service Animals

Frontier Airlines accepts for transportation in the passenger cabin, on all domestic and international flights and free of charge, Service Animals trained to assist a qualified individual with a disability. Only dogs are accepted as Service Animals. Also, Frontier accepts fully trained Psychiatric Service Animals as trained Service Animals. Passengers traveling with a Service Dog must complete and submit the DOT’s Service Animal Air Transportation Form online a minimum of 48 hours before the scheduled departure, or for reservations booked less than 48 hours before flight departure, in-person to a Customer Service Agent upon arrival at the airport. The Service Dog may sit at the passenger’s feet or on the passenger’s lap if the animal is small enough. Service Dog may not sit in the aisle or another seat. Passengers traveling with a Service Dog may be seated anywhere, except an emergency exit row.
