Plans don’t always go the way we expect. You book a flight, and then something comes up—maybe work changes, family emergencies, or just a change of mind. That’s why it’s important to know what your options are if you need to cancel or change your Allegiant Airlines flight.
Allegiant has a few rules when it comes to cancellations, and they’re a bit different from other airlines. But don’t worry—this guide breaks everything down for you in plain and easy-to-follow steps. Whether you’re canceling a trip, dealing with a missed flight, or just trying to understand your booking better, this guide will help you understand Allegiant Airlines Cancellation Policy. Let’s walk through it together and help you make the best choice for your travel plans.
The 24-Hour Refund Policy
Allegiant Airlines follows a basic rule set by the U.S. Department of Transportation: if you cancel your flight within 24 hours of booking, and your flight is scheduled at least 7 days away, you’re eligible for a full refund.
This applies to all travelers, regardless of ticket type. The key here is acting fast. Once the 24-hour period passes, your ticket becomes non-refundable unless you’ve purchased Trip Flex (more on that below).
Important:
- The 24-hour window begins from the moment you book your flight, not from the time of payment confirmation or email receipt.
- You must cancel through Allegiant’s official website or by calling their support team.
➡️ Tip: Always note your booking time. Setting a quick reminder can save you money if you change your mind.
Non-Refundable Tickets
Allegiant’s base fares are low, but that comes with strict terms. Once the 24-hour grace period passes, tickets become non-refundable.
This means if you cancel your flight, you won’t get your money back. You may receive a credit voucher for future travel, depending on the situation, but don’t count on a full refund unless you’ve added extra protection during Allegiant airlines booking online.
Exceptions:
- If Allegiant cancels or changes your flight by more than 2 hours, you may be eligible for a refund.
- Some travel insurance policies may cover your loss if the cancellation is due to illness or emergency.
What is Trip Flex?
Trip Flex is an optional add-on you can purchase while booking. It gives you flexibility in case your plans change. With Trip Flex, you can:
- Change your flight date or destination once
- Make name corrections
- Cancel your trip without paying a cancellation fee
The biggest benefit? You can make these changes up to one hour before your flight without a penalty. Without Trip Flex, changes can cost up to $75 per person.
Is It Worth It?
If you’re the kind of traveler who might shift plans, Trip Flex is a smart buy. It’s peace of mind for a small extra fee.

What Are Flight Credits?
If you’re not eligible for a refund, Allegiant may offer you a flight credit. These are vouchers that can be used to book another Allegiant flight in the future.
- Credits are usually valid for 1 year from the date of issue.
- You can use them online when making your next Allegiant airlines booking online.
- Flight credits are non-transferable, so only the original traveler can use them.
Tip: Keep a copy of the email with your credit code. You’ll need it during checkout when rebooking.
Allegiant Airlines Missed Flight Policy
Missing a flight is frustrating, but it happens. Allegiant’s policy is strict in this area.
If you miss your Allegiant airlines missed flight and didn’t purchase Trip Flex, you’ll likely lose the value of your ticket. There are no standard rebooking options or refunds unless:
- You contact customer support immediately
- The delay was due to a medical emergency (with documentation)
With Trip Flex, you can cancel up to one hour before the flight. If you miss your flight without using that option, you may still receive credit for future use, depending on the circumstances.
