How Much More Can Allegiant Grow?

In the past few years, American low-cost carrier Allegiant Air has been on a mission to grow and keep growing. Using Airbus A319s and A320s, Allegiant retired the aging McDonnell Douglas MD-80 fleet. And, since then, with lower costs, the airline has launched a host of new nonstop routes.

So, how much more can Allegiant grow?

Allegiant Air operates a more point-to-point network. This includes connecting smaller, regional destinations in the United States with tourist destinations like Los Angeles, Las Vegas, Myrtle Beach, Phoenix, Savannah, and a host of cities in Florida including Orlando, Fort Lauderdale, and Tampa among others. However, Allegiant operates most of these routes seasonally and on a limited frequency of a few times per week.

That being said, there is a lot of room for the carrier to grow. There are several gaps in the carrier’s maps that could benefit from additional low-cost service. Major cities like Seattle, Portland, Dallas, Philadelphia, and Atlanta see zero services on Allegiant.

Furthermore, Allegiant does not fly to Hawaii. This is one of the most popular leisure destinations in the United States without service onboard Allegiant. And, given Southwest’s successful entry into the market in 2019, there could be room for more carriers. Especially if Allegiant were to fly from cities like Las Vegas or Phoenix to Hawaii.

Could Allegiant introduce a true premium economy?

For now, Allegiant Air operates much shorter routes. But, longer ones are coming. Allegiant’s longer routes include services from places like Grand Rapids, Michigan and Cincinnati, Ohio to Los Angeles or Las Vegas to Knoxville, Tennesee, Allegiant could see a market for a few A320s to fly with a premium economy.

Premium economy could take a number of different iterations. Allegiant could go something similar to LATAM and block out a middle seat for more room, add a carry-on bag, and priority boarding. This would give Allegiant some flexibility to the cabin configuration without having to install a new product.

Or else, Allegiant could go based on its trials and add a couple of rows of extra-legroom seats and sell those as a premium economy product. This would mean a couple of alterations on the interior of the aircraft and might be a bit more costly for Allegiant.

Lastly, Allegiant could go for something along the lines of Spirit’s Big Front Seat. This would see Allegiant add a few rows of seating similar to domestic first-class seats on a major U.S. carrier. But, like the previous option, this would mean some change to the interior configuration of Spirit’s aircraft.


Allegiant does not have a lot of aircraft on order. Furthermore, the carrier’s current fleet of just under 100 A319 and A320 aircraft are heavily utilized. Although, there may be some room for seasonal flights here and there. But, a major expansion into a new market like Hawaii would require some more aircraft than Allegiant currently has. Or else, Allegiant would have to alter its current services to make it work. Perhaps Allegiant could place a new order for A320neo family aircraft.
