Austin’s Airport Is Losing Flights From This Low-cost Carrier — What to Know

Low-cost Allegiant Airlines plans to close its crew and aircraft base at Austin-Bergstrom International Airport (AUS) and reduce its routes by nearly a dozen early next year.

Starting Jan. 7, 2025, the airline will shift its operations over to the airport’s main terminal. The Central Texas airport, which has two terminals, has been undergoing major renovations since 2017. Allegiant Airlines currently flies out of the smaller South Terminal, which is scheduled to close soon as part of the larger construction plans.

“Allegiant will close their base in 2025, but they will continue to operate out of the South Terminal after their base operation ends,” a spokesperson from the airport authority shared in a statement with T+L. “Their transition to the Barbara Jordan Terminal will happen sometime before the South Terminal closure, which is anticipated to occur in 2026.”

Since early 2021, Austin has served as a hub for the low-cost airline, which has operated up to 40 weekly flights at its peak. However, according to new data from Cirium, an aviation analytics company, Allegiant will significantly reduce services to the following destinations starting in January 2025:

• Bozeman, MT (BZM)
• Cincinnati (CVG)
• Des Moines (DSM)
• Eugene (EUG)
• Grand Rapids (GRR)
• Knoxville, TN (TYS)
• Louisville (SDF)
• Santa Ana (SNA)
• Sarasota (SRQ)
• Washington-Dulles (IAD)

Once renovations are complete, it’s possible that Allegiant could reestablish its crew base in the future. The new Concourse B at Austin Airport, slated to be finished by 2030, will house 10 more gates and a direct connection to the main Barbara Jordan Terminal. 

Austin’s airport is no stranger to changes, as two major carriers exited the market earlier this year. American Airlines ended nearly two dozen routes from the metropolitan area, and Virgin Atlantic suspended flying to London Heathrow Airport less than two years after the inaugural service. In response, Delta Air Lines increased frequencies on several domestic flights, making Austin a “key access point to facilitate connections,” according to the carrier. 

A representative from Allegiant did not respond to T+L’s request for comment.
