We want you to be able to take your favorite furry friend with you when you travel. That’s why we allow small domesticated pets to travel on all domestic flights including Puerto Rico and St. Thomas, U.S.V.I. in the guest cabin:

Please note that as of January 11th, 2021, emotional support animals (ESAN) will be required to travel as pets per updated Department of Transportation requirements. In order to travel as a pet, the animal must meet and follow the below requirements.

Spirit will only allow the following pets on the aircraft:

  • Domestic dogs
  • Domestic cats
  • Small household birds (except to / from Puerto Rico and the U.S.V.I. )
  • Small domestic rabbits (except to/from Puerto Rico and U.S.V.I)

IMPORTANT: Birds that are not considered household birds include farm poultry, waterfowl, game bird, birds of prey, and flightless birds.

Brachycephalic breeds, also known as snub-nosed dogs, may be more vulnerable to risks during air travel. We recommend consulting with your veterinarian to be aware of any special precautions while flying.

To add a pet to your reservation, chat with us here. It’s helpful to make these arrangements when making your travel plans with Spirit due to a maximum of six pet containers permitted on the aircraft during all domestic flights (including Puerto Rico and St. Thomas, U.S.V.I). View our current charges for pets here.
