Passengers traveling with their furry friends? Here we have discussed the Spirit Airlines pet policy in very simple and clear way. Spirit lets you fly with small pets in the cabin, never into cargo! Domestic dogs, cats, small household birds, and rabbits are allowed, with some restrictions necessary depending on the situation. Birds and rabbits cannot be carried to Puerto Rico or the USVI, while you need a rabies certificate or a health certificate in the other case.
Spirit flight with animals:
Spirit Airlines' pet travel policy permits only soft-sided carriers up to 18″ × 14″ × 9″, and the pet and the carrier should weigh less than 40 lbs. Throughout the flight, the pet should remain within the carrier, placed under the seat. You can bring two pets of the same breed in one carrier, but a passenger can only bring one carrier.
There is a maximum of six pet carriers allowed onboard, so the earlier you book, the better your chances of securing a spot. Certain breeds, especially snub-nosed dogs, could be theoretically at a higher risk during flights, so check with your vet to be on the safe side.
How to add pet to Spirit flight?
Want to secure your pet's seat early? Here's how to add a slot with Spirit Pet Policy:
Add during booking – Calling Spirit or chatting with customer service to add your pet to your reservation is the best way to do it early, as only six pet containers are allowed per flight.
Check carrier compliance – Check that it is the proper size, is soft-sided, has ventilation, has a waterproof bottom, and allows your pet to stand and turn around comfortably.
Prepare documentation – For Puerto Rico, a rabies vaccination certificate is to be taken along. While flights to the USVI may require a health certificate, regular domestic flights do not.
Pay the fee – The usual rate stands around $125 one way per carrier at the ticket counter during check-in.
Check-in with a pet – Must be checked in at the ticket counter (not at curbside or self-service). Arrive early to allow extra time.
Boarding and seating – Considered carry-on for you. You can sit anywhere you like, except in the exit rows and the first row. Make sure your carry-on fits under the seat in front of you.
During the flight – The Spirit Air Pet Policy clearly states that the pet has to stay in the carrier, be calm, remain harmless, and odorless; no need to potty break on the plane.
Spirit Airlines’ Animal Policy Tips
According to Spirit Airlines' animal policy, Service animals or trained dogs fly free of charge with proper DOT forms and pre-approval; emotional support animals are now treated as pets and must follow the pet policy.
Exotic pets, such as snakes, rodents, and reptiles, are prohibited.
Brachycephalic-type dogs need special attention, so be sure to check with your vet.
Conclusion
Traveling with pets makes for a very memorable experience for both. The Spirit Pet Travel Policy is simple: if small, pets can travel with one in schedule-approved carriers, which should not exceed the weight limit, while their spots must be booked in advance. All paperwork and fees should be taken care of at least at check-in. With a little preparation effort, your travel companion will be able to assist you along the way, safely. Good luck and safe travels for you and your furry friend!
