After an absence of more than six years, Las Vegas-based Allegiant Air is resuming service at Colorado Springs Airport with three new routes starting early next year.

This nonstop flight is part of “one of Allegiant’s largest service expansions in its history,” the company says.

Starting early next year, Allegiant Air is adding three new cities to its roster of nonstop routes: Colorado Springs; Gulf Shores, Alabama; and Columbia, South Carolina.

Allegiant Air announced a major expansion Tuesday, unveiling dozens of new routes and a handful of new airports.

In 2025, Allegiant Airlines will offer routes at the Colorado Springs Airport as well as two new routes out of the Denver International Airport.

Colorado Springs Airport will add several new nonstop routes through Allegiant Airlines, according to a Tuesday news release.
