Passengers benefit from the Allegiant Air Cancellation Policy which provides clear cancellation and refund options. A 24-hour risk-free window allows cancellations for full refunds on bookings made at least seven days before departure. Afterward, non-refundable tickets usually qualify for travel credits. Purchasing Trip Flex allows passengers to change or cancel more easily. If Allegiant cancels a flight, passengers can receive refunds or free rebooking. Cancellation requests can be handled online, via the mobile app, or by contacting Allegiant’s support team. Checking fare rules before canceling helps ensure passengers know refund eligibility and avoid unnecessary charges when plans shift.
