Quick summary
A budget airline has announced 30 new routes launching in 2026, marking its largest expansion since last year.
Three new cities will be added to the network: La Crosse, Wisconsin; Columbia, Missouri; and Philadelphia, with a return to Trenton, New Jersey.
The expansion focuses on connecting leisure travelers from smaller secondary airports to vacation destinations, though some new routes will serve major airports.
Several airports, such as Gulf Shores and John Wayne in Orange County, will see significant increases in service.
What to consider
Some routes are reinstatements of previously operated flights, with several not flown since the late 2010s or 2023.
The expansion is supported by the airline's growing fleet of new aircraft, enabling more leisure-focused routes.
The airline is also considering updates to its loyalty program and possible addition of on-board Wi-Fi.

Allegiant Air is plotting a major expansion in 2026.
The budget airline announced a whopping 30 new routes that will take flight over the winter, spring and early summer months next year.
This blockbuster route announcement includes three all-new cities for the Las Vegas-based ultra-low-cost carrier: La Crosse, Wisconsin; Columbia, Missouri; and Philadelphia. And Allegiant will make its return to Trenton, New Jersey, for the first time since the COVID-19 pandemic.
It’s Allegiant’s biggest expansion since last year, when it unveiled 44 new routes that launched earlier this year.
And it will see the airline double down on its tried-and-true business model: shuttling passengers to vacation destinations from (mostly) smaller secondary airports — though the three new routes from Philadelphia International Airport (PHL) are an exception here.
“These additions provide convenient options for leisure travelers and reflect our commitment to expanding service where demand is strong,” Allegiant Chief Officer Drew Wells said in a statement announcing the news.
Among the cities Allegiant already serves, there were two big winners.
Gulf Shores International Airport (GUF) in Alabama will get five new Allegiant routes in 2026. That’s after the airline first started flying to the airport in 2025.
And John Wayne Airport (SNA) in Orange County, California, will get five new routes of its own.

Other winners in Tuesday’s announcement include Fort Lauderdale-Hollywood International Airport (FLL), which gained four nonstop routes from cities across the country. And three new or returning cities will connect to Mesa Gateway Airport (AZA), a secondary airport in the Phoenix area.

Expect more of these leisure-focused routes in the years to come.
Speaking to TPG this past summer, Wells, the chief commercial officer, said the carrier has identified some 1,400 routes the airline believes "fit our mold very well."
“Migration patterns are crazy in the U.S. People are frequently moving from one area to others, and creating new opportunities all the time," Wells told me in July at Allegiant's Vegas headquarters. "There’s a great opportunity for Allegiant that exists."
