The Allegiant Air Cancellation Policy makes it easier for travelers to manage cancellations. Customers can cancel bookings within 24 hours for a full refund if departure is at least seven days later. Non-refundable tickets canceled afterward usually provide credits, not cash refunds, while Trip Flex offers added flexibility. If Allegiant cancels a flight due to operational issues, passengers are eligible for refunds or free rebooking. Cancellation requests can be made through the airline’s website, app, or customer support. Reviewing fare rules ahead of time helps passengers understand refund eligibility and fees, ensuring a smooth travel adjustment process.
