To cancel your Allegiant flight without facing a penalty, take advantage of the 24-hour cancellation policy. This allows you to cancel your booking within 24 hours for a full refund, provided your flight was booked at least seven days before the scheduled departure. Beyond this window, you’ll be subject to a $75 cancellation fee per passenger.
However, if you purchase Trip Flex during booking, you can cancel or make changes to your flight itinerary without incurring penalties as long as changes are made at least 72 hours before departure. Trip Flex not only waives cancellation fees but also offers the flexibility to adjust your travel plans without any added stress. Without Trip Flex, cancellations outside the 24-hour window will result in fees, and refunds will be given as travel credits.
