The Spirit cancellation policy is crystal clear. The best thing about Spirit's cancellation policy is that there are no restrictions for passengers. You can cancel your Spirit Airlines flight at any time, regardless of whether your plans have changed or you are unable to travel because of any reason. However, your chances of receiving a refund from Spirit Airlines are very slim if you cancel within the hour of departure. If you believe you have a valid reason to cancel your flight, you can contact our to request a refund.
