How can I avoid the Allegiant flight change fee?
Want to skip Allegiant's flight change fee? You absolutely can if you act fast, plan smart, and use the right tools. Here’s how to avoid paying extra when plans change:
★ Cancel within 24 hours (if your flight is 7+ days away): Cancel your flight within 24 hours of booking, if you booked it at least a week in advance, and receive a full refund. No fees, no stress.
★ Add Trip Flex™ when booking: Trip Flex is a low-cost add-on (around $29–$43) that lets you change or cancel your flight once, up to 1 hour before departure, without paying the standard $75 change fee. You'll avoid the change fee, but you must still pay any fare difference. Think of it as peace of mind in case life changes plans for you.
★ Avoid changes within 7 days of departure (without Trip Flex): Without Trip Flex, you can’t make changes within 7 days of your flight. Doing so means losing your booking entirely—no refund or credit. So, if you don’t have Trip Flex, finalize your changes at least a week before departure to avoid penalties.
★ Use credit vouchers for eligible cancellations: If you cancel a flight outside the 24-hour window but more than 7 days before departure, and you didn’t buy Trip Flex, you’ll get a credit voucher (minus fees) to use on a future Allegiant trip. Track your voucher in your myAllegiant™ account.
Fond Tip: Make vacation package changes or cancellations at least 72 hours before departure to avoid losing credits or paying higher fees.
