Even though SpiritAirlines loves animals, they do not allow pets to travel internationally. SpiritAirlines does allow service/emotional support animals, though. Depending on the international destination, specific documentation regarding the service/emotional support animal may be required. Customers should contact the appropriate consulate or embassy prior to departure to ensure they have all necessary documents and all appropriate procedures are followed.
If traveling with an emotional support animal, a letter from your physician is still required as well.
