If you're wondering whether you can cancel your Allegiant flight without a penalty, it depends on the fare type you purchased and the timing of your cancellation. Allegiant offers a 24-hour risk-free cancellation period for tickets booked directly through the airline, which allows you to cancel your flight without any penalty as long as it's done within 24 hours of booking and the flight departure is at least seven days away.

If you miss the 24-hour window, Allegiant’s standard policy is to charge a cancellation fee. However, travelers who purchased Trip Flex—a special add-on that allows for more flexibility—can cancel their flight without incurring any penalties or change fees, up to 72 hours before departure. Without Trip Flex, you'll likely face a cancellation fee, and the remaining amount will be issued as non-refundable credit for future travel.

When planning your trip, it's a good idea to familiarize yourself with Allegiant’s policies and consider purchasing Trip Flex for added flexibility.
