Allegiant Air

Allegiant Air operates as an ultra-low-cost carrier headquartered in Enterprise, Nevada, serving the Las Vegas metropolitan area. The airline was established in 1997 by Gary Kelly and Robert Crandall to connect smaller cities with limited commercial service to popular leisure destinations like Florida, Arizona, and California. Unlike traditional network carriers, it avoids complex hub-and-spoke systems and business class seating, focusing instead on a point-to-point model using Airbus A320 family aircraft.

The company's revenue strategy relies heavily on unbundling services. Base fares remain low to attract price-sensitive travelers, while profitability comes from ancillary fees for checked bags, seat selection, and onboard refreshments. In May 2026, Allegiant Travel Company announced a $1.5 billion agreement to acquire Sun Country Airlines. This merger aims to create a larger entity capable of competing with major legacy carriers while maintaining independent operations and distinct customer experiences during the transition period.

Recent expansion efforts in August 2026 highlight the airline's focus on seasonal demand. Allegiant added nine new nonstop routes to Florida for Spring 2027, including seasonal flights from Portsmouth, New Hampshire; T.F. Green Airport in Rhode Island; and Grand Forks, North Dakota. These additions join existing service to Sarasota-Manatee Airport and three new Gulf Coast flights, reinforcing its dominance in the sunshine route sector. [edit]
