Allegiant Air's cancellation policy allows passengers to cancel flights for a credit voucher or, in some cases, a refund. To be eligible for a credit voucher, cancellations must be made at least 7 days before departure, with a fee of up to $75 per passenger, per segment. The credit voucher is valid for one year. For a refund, cancellations must occur within 24 hours of booking if the flight is at least 7 days away. Trip Flex protection can be purchased for greater flexibility, allowing changes without standard fees. Contact Allegiant Air customer service at +1-855-200-0640 for assistance.
