About

Allegiant Air is a US ultra-low-cost carrier headquartered in Las Vegas, Nevada. Founded in 1997, the airline operates a unique business model focused on connecting small and mid-sized cities directly to leisure destinations, primarily in Florida, Arizona, and Nevada.

Unlike traditional hub-and-spoke carriers, Allegiant flies point-to-point routes between underserved markets and popular vacation spots. This means travelers from smaller cities can often fly nonstop to places like Las Vegas, Orlando, or Phoenix without connecting through major hubs.

Allegiant operates an all-Airbus fleet (primarily A320 family aircraft) and serves over 120 domestic destinations with no international routes. The airline is known for its leisure-focused schedule, often operating routes only a few times per week rather than daily.
