Allegiant Airlines' cancellation policy provides passengers with flexibility and options for managing their travel plans. Cancellations made within 24 hours of booking, with departure at least seven days away, qualify for a full refund. Beyond this window, cancellations may incur fees, and any remaining funds are issued as travel credit. Trip Flex protection allows changes or cancellations without penalties. Non-refundable tickets are typically ineligible for cash refunds, adhering to Allegiant’s guidelines.
