The Allegiant Air Cancellation Policy offers passengers flexibility when travel plans change unexpectedly. Allegiant provides a 24-hour risk-free cancellation period, allowing customers to cancel bookings for a full refund if flights are scheduled seven or more days later. Beyond this window, cancellation fees may apply depending on fare type. Non-refundable tickets often qualify for credits rather than cash refunds, while certain fare protections offer more flexibility. If Allegiant cancels a flight, passengers are eligible for rebooking at no cost or a refund. Managing cancellations is simple through Allegiant’s website, app, or customer service, ensuring smooth adjustments for travelers.
