Spirit Airlines’ cancellation policy varies based on when and how you cancel. Generally, if you cancel within 24 hours of booking and the reservation was made at least 7 days before departure, you can receive a full refund. Outside this window, cancellation fees apply, ranging from $10 to $50 depending on when and how you cancel. If you purchased a ticket through Spirit’s website or reservation center, you can cancel online or by phone. Refunds are issued as a credit for future travel, valid for up to 60 days. Changes and cancellations within 24 hours of departure incur additional fees.
