The Allegiant Air cancellation policy catches many travelers off guard, because Allegiant is an ultra-low-cost carrier where most fares are non-refundable and changes and cancellations carry fees. But there are still ways to protect your money — the 24-hour rule, Trip Flex, travel vouchers, and airline-caused cancellations. This guide explains the Allegiant Air change and cancellation policy clearly and how to keep the most value.

The 24-hour rule applies to Allegiant too
Under U.S. Department of Transportation rules, if you booked at least 7 days before departure you can cancel within 24 hours of purchase for a full refund — no fee, even on a non-refundable Allegiant fare. This is your cleanest path to all your money back. Details: the 24-hour flight cancellation rule.
Change and cancel fees outside the window
Outside the 24-hour window, Allegiant charges a change or cancellation fee per segment, and the remaining value is usually issued as a travel voucher rather than cash. Like other ULCCs, acting earlier generally costs less. You also pay any fare difference when changing. (Exact amounts vary by fare and change often — call to confirm.)
| Situation | Typical outcome |
|---|---|
| Within 24 hours (booked 7+ days out) | Full cash refund |
| Change outside window | Change fee + fare difference |
| Cancel outside window | Cancel fee; remainder as a travel voucher |
| With Trip Flex purchased | One fee-free change/cancel before departure |
| Allegiant cancels your flight | Cash refund to original payment method |
| No-show | Usually nothing — cancel first |
Trip Flex: Allegiant's flexibility add-on
Allegiant's Trip Flex option, bought at booking, lets you change or cancel once without the usual fee (up to a set time before departure). If there's any chance your plans will move, Trip Flex often pays for itself versus paying a change or cancel fee later. Our agents can tell you whether it's worth adding for your trip.
When Allegiant owes you a cash refund
If Allegiant cancels your flight, delays it significantly, or makes a schedule change you don't accept, you're entitled to a cash refund to your original payment method — not just a voucher — even on the cheapest non-refundable fare. Don't settle for a voucher if cash is your right.
Travel vouchers: don't let them lapse
When you can't get cash, Allegiant typically issues a travel voucher with an expiration date. Set a reminder and use it before it expires — our agents can apply an existing voucher to your next booking.
How to change or cancel an Allegiant flight
- Find your booking with your confirmation code and passenger name.
- Check the 24-hour window first — it's the difference between cash and a voucher.
- See if you have Trip Flex — it waives the usual fee.
- Act early to minimize fees and keep more value.
- Cancel before departure — never no-show.
