This includes Legroom+ seats, exit-row seats, front-row seats, and the popular “Giant Seats” on select aircraft.

How to Rebook an Allegiant Airlines Business Class Flight After Cancellation?
Since Allegiant does not operate a traditional business class cabin, passengers often confuse premium seat options with a business-class product. When travelers reference an “Allegiant Airlines business class flight,” they are usually referring to Giant Seats or other upgraded seating categories.
Rebooking after cancellation works like this:
Visit Manage Travel on the Allegiant website.
Enter your confirmation number and last name.
Select your canceled flight and choose a new travel date.
Choose your upgraded seating again—Legroom+, Giant Seats, or preferred seats.
Pay any fare or seat difference.
If you had purchased an upgraded seat earlier, Allegiant does not automatically transfer upgrade fees—you must select the seat again during rebooking.
What Happens if I Need to Change My Allegiant Airlines Business Class Flight Time?
If you need to change your flight time—even when using upgraded seating—the process is straightforward:
Allegiant allows flight changes for a fee, depending on the fare and timing.
After selecting a new flight time, you can choose an upgraded seat again through Allegiant Airlines seat selection.
If the upgraded seat type you previously had isn’t available on the new flight, Allegiant does not guarantee a replacement.
You may need to pay the difference if the new seat option is more expensive.
Even though there is no true Allegiant Airlines first class upgrade, upgrading to Giant Seats or exit-row seats remains consistent across all flight times.
How to Get a Free Allegiant Airlines Business Class Upgrade?
The term “free upgrade” is rare with Allegiant, especially because the airline does not offer loyalty tiers like major carriers and does not operate business class. However, there are a few situations where you might get a complimentary enhanced seat:
✔ When a flight is oversold
Passengers may be moved to better seats if Allegiant needs to rearrange travelers.
✔ When your purchased seat becomes unavailable
If the airline changes your aircraft type, you could be reseated in a better seat at no extra cost.
✔ When online check-in assigns you a seat
Occasionally, though rare, passengers are given premium seats automatically if standard seats are full.
While free upgrades aren’t part of a standard program, improved seating is still possible without paying.
How to Upgrade to Allegiant Airlines Business Class at the Airport?
Looking to upgrade at the last minute? The airport is the best place to check for remaining premium seats. Here’s how:
Visit the ticket counter or gate agent.
Ask whether Giant Seats, Legroom+, or front-row seats are still available.
Pay the upgrade fee directly at the airport.
Airport upgrades are usually cheaper if seats are unsold, though availability is limited. This remains the closest thing to a same-day Allegiant Airlines business class upgrade experience.

Technically, Allegiant does not have a point-based frequent flyer program like other major airlines. That means:
You cannot use miles or loyalty points for an Allegiant Airlines business class upgrade.
You cannot use travel credit cards to redeem points for seat upgrades directly through Allegiant.
All upgrades must be purchased with cash or card.
However, some third-party travel cards allow you to redeem statement credits for travel expenses—including Allegiant upgrades—after you pay.
