Allegiant Air

About Allegiant Air

Allegiant Air is an American ultra-low-cost airline headquartered in Las Vegas, Nevada. The airline focuses on serving leisure traffic from small and medium-sized cities that it considers to be underserved, offering low base fares with minimal inclusions and a greater number of add-on fees.
Allegiant was founded in 1997 and is wholly owned by Allegiant Travel Company, a publicly traded company with 5,600 employees and over US$2.6 billion in market capitalization as of 2016. The airline is the fourteenth largest in North America.
Allegiant Travel Company acquired Sun Country Airlines on May 13, 2026, in a roughly $1.5 billion deal and plans to fold all operations under the Allegiant Air brand while maintaining a significant presence at Sun Country's base at Minneapolis–St.
