The Spirit Airlines pet fee is a major consideration for travelers planning to fly with pets in 2026. Spirit Airlines allows small domesticated dogs, cats, rabbits, and household birds to travel inside the cabin on eligible domestic flights, including routes to Puerto Rico and the U.S. Virgin Islands such as St. Thomas. Travelers flying with pets must pay a $125 fee each way per pet carrier, and all pets must remain inside an approved soft-sided carrier during the journey.
Spirit Airlines has become a popular option for budget-conscious pet owners because of its affordable airfare and relatively simple in-cabin pet policy. However, travelers should understand the airline’s pet carrier requirements, booking process, flight restrictions, and updated travel rules before departure.
