Spirit airline flight cancellation policy is set up to allow for flexible travel at affordable prices. If the flight is at least a week out, cancellations submitted within 24 hours of booking are fully refundable. Other cancellations are subject to fines, which change based on how close to departure the cancellation takes place. Refunds from Spirit are given as one-year travel credits. The purpose of Spirit Airlines' flight cancellation policy is to provide passengers with affordable alternatives for managing schedule modifications and protecting their trip budget.
