Small domestic dogs, cats, household birds and household rabbits are the only pets accepted to travel in the passenger cabin. However, household birds and rabbits are not accepted on Spirit Airlines flights to/from Puerto Rico and St. Thomas, the U.S. Virgin Islands.

Pets in the Passenger Cabin

The number of pets allowed in the passenger cabin is subject to space availability, so you should reserve space for your pet at the time of or immediately after booking. You can add a pet to a reservation by calling Spirit Airlines Reservations Center. A pet cannot be booked online. Passengers traveling with pets must check in at the ticket counter (Online or Kiosk Check-in is not available) and should allow extra time beyond normal check-in guidelines.

Spirit Airlines does not require a health certificate for pets traveling in the passenger cabin, except for flights to the U.S. Virgin Islands. To be accepted, pets must be at least 8 weeks old, fully weaned, harmless, and odorless. Spirit Airlines maintains the right to refuse acceptance of any animal that is exhibiting aggressive behavior and will remove any animal that becomes offensive or causes a disturbance during transit, at the first enroute stop.

The pet must require no attention and be completely contained within the pet carrier at all times on board the aircraft. The passenger is responsible for assuring that the container meets all government requirements, but the container is subject to inspection and approval by Spirit Airlines. The combined weight of the pet and carrier must not exceed 40 lbs (18.14 kg).

Spirit Airlines requires that the container must be able to fit under the seat and not exceed the following dimensions: 18 x 14 x 9 in (45.72 x 35.56 x 22.86 cm). Only soft-sided pet carriers are accepted, but not the type which permit the pet’s head to remain outside the container. The pet must be able to stand upright and move about comfortably in the pet carrier.

Spirit Airlines restricts the number of pets and pet carriers allowed as follows:

  • A maximum of 4 pet containers per flight.
  • Only one pet container per passenger.
  • A maximum of 2 pets per container, as long as pets are similar and there is enough room for both of them in the container.


Pets are accepted for transportation only for a service fee of $110 per container, each way. The fee is non-refundable and must be paid at the time the reservation is made. The pet will count as one-plus-one carry-on luggage.

Service Animals

Spirit Airlines allows Service Animals to travel in the passenger cabin on any Spirit Airlines flight, domestic or international. Service Animals are accepted based on the reasonable credible verbal assurance from the individual with the disability using or accompanying the animal or evidence that the animal is a Service Animal (identification cards or written documentation regarding the medical need for the presence of the animal in the cabin).

Emotional Support Animals and Psychiatric Service Animals are accepted for transportation in the passenger cabin, on all flights, provided that the passenger submits the required form to Spirit Airlines at least 48 hours before departure and has current documentation (no older than one year preceding the date of your scheduled initial flight). Emotional Support Animals and Psychiatric Service Animals must be at least four months of age.

There is a limit of 3 Service Animals per passenger and 1 Emotional Support Animal or Psychiatric Service Animal per passenger.

Passenger traveling with a Service Animal must check in at the ticket counter, one hour before the check-in time for the general public, for document verification. For international flights, it is the passenger’s responsibility to follow any applicable regulations. Passengers traveling with a Service Animal may choose to sit anywhere they wish, except emergency exit rows. If available, they are seated in the bulkhead row, where the animal can lie on the floor at the passenger’s feet without blocking an aisle or other area that must remain clear for emergency evacuation.
