Does Spirit allow you to change flights but it comes with certain conditions and fees. If you need to change your flight on Spirit, you can do so online, by phone, or at the airport, depending on your preference. The fees for changing your flight vary based on factors like the fare type, route, and when you make the change. Free Spirit loyalty members may receive reduced fees depending on their membership level. It’s always a good idea to check Spirit’s policies and any fees associated with changing your flight before making adjustments.
