Spirit Airlines cancellation policies are designed to offer flexibility and convenience to passengers. The airline allows customers to cancel their reservations within 24 hours of booking without any penalty. However, after this period, travellers would have to pay a fee for cancelling or changing their flight plans. While Spirit Airlines does not offer refunds, they do provide credit vouchers that can be used towards future flights with the airline. Furthermore, if the airline cancels a flight due to operational issues or weather conditions, they offer several options including rebooking on another flight at no extra cost or providing a full refund. Overall, Spirit Airlines aims to make its cancellation policies as simple and understandable as possible for its customers while balancing business needs and regulations in an ever-changing travel landscape.
