Allegiant Air (usually shortened to Allegiant and stylized as allegiant) is an American discount airline that operates scheduled and charter flights. As a major air carrier, it is the ninth-largest commercial airline in the US. It is wholly owned by Allegiant Travel Company, a publicly traded company with 4,000 employees and over US$2.6 billion market capitalization. The corporate headquarters are in Summerlin, Nevada, a suburb of Las Vegas.
Allegiant also earns commissions by offering hotel rooms, car rentals and admission to tourist attractions on its website. It sells package vacations under the brand name Allegiant Vacations. The company has arrangements with 34 hotels in Las Vegas and 21 in the Orlando and Daytona Beach, Florida, areas. In 2008, the airline sold 400,000 hotel room nights. Commissions on hotel and rental car packages are up to one-third of the airline's revenue.
In March 2010, Allegiant purchased six used Boeing 757-200 jetliners as part of plans to begin flights to Hawaii, with deliveries from early 2010 to the fourth quarter of 2011. It gained the approval for type with the FAA in July 2011, and then worked with the FAA to obtain the appropriate ETOPS rating in order to be able to serve Hawaii. Allegiant no longer operates nonstop service to Honolulu from Las Vegas.
