The Spirit Airlines baggage policy is an important consideration for anyone planning to fly with the ultra-low-cost carrier. Known for offering some of the cheapest base fares in the airline industry, Spirit keeps ticket prices low by separating the cost of baggage, seating, and other extras. Under this policy, every passenger is allowed one personal item for free, which must fit under the seat in front of them and not exceed 18 x 14 x 8 inches. Items like small backpacks, purses, or laptop bags typically qualify. However, anything larger, such as a standard carry-on suitcase, is subject to additional fees. Carry-on baggage must not exceed 22 x 18 x 10 inches, and the fee for bringing one varies depending on when and where you purchase the allowance—buying it during initial booking is the most affordable option, while paying at the airport gate can be significantly more expensive. Spirit also charges for checked luggage, with each checked bag limited to 40 pounds and 62 linear inches. If a bag exceeds these weight or size limits, passengers will face hefty oversize or overweight fees. To help travelers save money, Spirit offers bundled options like the “Bundle It Combo,” which can include a carry-on, checked bag, seat selection, and priority boarding at a discounted rate. Because of the strict enforcement of these baggage rules, it’s essential to measure and weigh your luggage before heading to the airport. By fully understanding the Spirit Airlines baggage policy, travelers can avoid unexpected fees, streamline their check-in process, and enjoy a more budget-friendly trip. Proper planning and early booking of baggage options are key to getting the best value when flying with Spirit Airlines.
