If you cancel your Spirit Airlines flight after the 24-hour grace period, you may not be eligible for a full refund. Spirit typically offers future travel credits instead of refunds for cancellations made after the 24-hour window. However, if you have a refundable ticket or purchased flight protection, you may still qualify for a full refund. Cancellation fees are applied based on when you cancel and the type of ticket you purchased. To cancel and explore your options, go to the "Manage My Booking" section on Spirit’s website. For travelers who want more flexibility, considering flight insurance or a refundable ticket is the best option.
