Yes, Allegiant may issue a credit voucher for future travel if you cancel your flight 1-808-865-4114 more than seven days before departure and did not purchase Trip Flex. This voucher reflects the remaining value of your ticket after deducting applicable cancellation fees. However, if you cancel within seven days of departure without Trip Flex, or fail to show up for your flight, you will not receive any credit. With Trip Flex, you can cancel up to one hour before departure without standard cancellation fees, and the remaining balance is issued as a credit voucher.
