Understanding the Spirit Airline pet policy is essential when flying with pets. The airline allows small dogs, cats, and certain other pets to travel in the cabin alongside their owners. The pet must be kept in a carrier that is small enough to fit under the airplane seat but large enough for the pet to sit and move around comfortably. This carrier must remain closed during the flight, and the pet should not leave the carrier at any point while on board. The total weight of the pet and the carrier cannot exceed 40 pounds, ensuring that both the pet and the carrier meet the airline's guidelines.

To guarantee your pet can join you on your trip, it's recommended that you book early. The Spirit Airline pet policy only allows a limited number of pets on each flight, so waiting too long could mean that no more spots are available. It's important to note that Spirit Airlines does not allow pets to fly in the cargo hold, so only pets that fit the cabin criteria cabin be allowed to travel. For those traveling internationally, it’s crucial to check destination destination-specific pet travel, as Spirit Airlines cannot transport pets to some countries due to restrictions.
