Quick Overview: Allegiant Airlines Seat Upgrade During Online Check-In

Before diving into the details, here’s a fast breakdown:

• Yes, you can upgrade your seat during Allegiant’s online check-in.

• Upgrades depend entirely on remaining premium seat availability.

• Allegiant does not have traditional first or business class, so Allegiant Airlines premium cabin upgrade, Allegiant Airlines first class upgrade, and Allegiant Airlines business class upgrade refer to premium-style seating, not cabin-level upgrades.

• You can upgrade to:

  • Legroom+ seats

  • Exit row seats

  • Front-section seats

  • Preferred aisle/window seats

• Sometimes, last-minute upgrades are cheaper, but not always.

• Online check-in starts 24 hours before departure.

Now let’s explore how it all works.

Understanding How Allegiant Airlines Seat Upgrade Options Work

Allegiant Airlines follows an ultra-low-cost model where the base fare includes transportation only. Everything else—bags, food, boarding priority, and seats—is optional. This gives travelers flexibility and helps keep fares low.

Because seat selections are not included in the base fare, Allegiant Airlines seat upgrade options play a major role in the travel experience.

What Counts as an Upgrade on Allegiant Airlines?

Since the airline does not have premium cabins, an upgrade typically means moving to a more comfortable or conveniently located seat. The most common upgrade categories include:

1. Legroom+ Seats

These seats offer several extra inches of legroom. They are ideal for tall passengers, families, or those who want more comfort during the flight.

2. Exit Row Seats

Exit-row seats provide some of the most spacious legroom on the aircraft. Passengers must meet FAA safety guidelines to sit here.

3. Front-of-Cabin Seats

While not a premium cabin, these seats offer faster deplaning and a smoother ride experience.

4. Preferred Aisle or Window Seats

For travelers who want control over their view or movement, these are considered upgrade-worthy.

These are the options people refer to when searching for:

• Allegiant Airlines premium cabin upgrade

• Allegiant Airlines first class upgrade

• Allegiant Airlines business class upgrade

Although the names may sound premium, Allegiant simply offers different tiers of economy seating comfort rather than separate cabin classes.

Can I Get an Allegiant Airlines Seat Upgrade When Checking In Online?

Yes—Allegiant allows seat upgrades during online check-in, but seat availability is not guaranteed. Here’s how it works:

Seat Upgrade Availability During Check-In

When you check in online (24 hours before the flight), the system shows available seats. If premium seats—such as Legroom+, front-section, or exit-row seats—were not purchased by other passengers, you can select them at this stage.

Why Upgrading at Check-In Can Be a Smart Move

• Some premium seats may still be available.

• Prices are sometimes lower than earlier in the booking timeline, especially if the airline wants to fill seats.

• You get a chance to move away from the middle seats assigned automatically.

Why Upgrading at Check-In Can Be Risky

• High-demand flights may have already sold most premium seats.

• Families and groups may not find seats together.

• Prices can sometimes go up rather than down closer to departure.

In short, online check-in upgrades are available and often convenient, but the selection may be limited.

Allegiant Airlines Seat Selection — Why It Matters for Upgrades

Seat selection plays a huge role in how comfortable your journey will be. While Allegiant offers cheap fares, the standard seats can feel narrow and snug, especially on longer flights.

Here’s why choosing your seat early helps:

1. You Get First Access to Premium Seats

Seat upgrades are available even during booking, so you’ll find the widest selection.

2. Prices Are Often Lower Earlier

Allegiant’s seat-selection fees vary by flight, demand, and timing. When you book early, premium seats are often cheaper.

3. Families Can Sit Together More Easily

Waiting until check-in—when only a handful of seats may be left—can split up large groups.

4. You Avoid Middle Seats

Standard middle seats are usually what remains last.

If you rely only on check-in time, premium seat options may be fewer, especially on peak travel days.

Allegiant Airlines Premium Cabin Upgrade — What It Really Means

Many travelers expect traditional premium seating similar to major airlines. However, Allegiant only flies all-economy aircraft, so there are no lie-flat seats, no true first-class, and no business-class cabin.

Still, people often use terms like:

• Allegiant Airlines premium cabin upgrade

• Allegiant Airlines first class upgrade

• Allegiant Airlines business class upgrade

These terms refer to seat comfort within the economy cabin, not a separate class.

What You Actually Get with “Premium” Seating:

• Extra legroom

• A more comfortable seating position

• Quicker boarding or deplaning

• A more enjoyable in-flight experience

If you want any of these perks, upgrading during check-in is possible—but only if seats are still open.

How Much Does an Allegiant Airlines Seat Upgrade Cost?

Prices vary depending on flight length, route demand, and how close you are to departure.

Typical upgrade cost ranges:

• Legroom+ seats: $20–$45

• Exit-row seats: $25–$55

• Front-section seats: $10–$35

• Preferred window/aisle seats: $6–$25

During online check-in, prices may sometimes drop—but not always.

Tips to Improve Your Chances of Getting an Upgrade During Online Check-In

If your goal is to upgrade at check-in, use these strategies:

1. Start Check-In Exactly at the 24-Hour Mark

Premium seats sell fast, even at the last minute.

2. Use the Desktop Version of the Website

Sometimes, more seat options appear on the desktop portal than the mobile app.

3. Consider Traveling Off-Peak

Flights on Tuesdays, Wednesdays, and some Saturdays have more seat availability.

4. Look for Seat Changes at the Airport

If check-in is unsuccessful, try again at the airport kiosk.

5. Be Flexible

If you’re willing to move seats or travel solo, finding a premium seat upgrade becomes easier.

Conclusion: Should You Rely on Allegiant Airlines Seat Upgrade During Online Check-In?

Yes, you can upgrade your seat during online check-in with Allegiant Airlines, but availability is not guaranteed. If you truly care about comfort—extra legroom, better views, or avoiding the middle seat—booking early or upgrading shortly after booking is the safest option.

If you’re seeking:

• Allegiant Airlines premium cabin upgrade

• Allegiant Airlines first class upgrade

• Allegiant Airlines business class upgrade

Remember that Allegiant offers enhanced seating but does not operate premium cabins.

Still, the airline’s upgraded seating options offer comfort and convenience at a great price—especially when you secure them early or during check-in.
