Allegiant

Allegiant most commonly refers to Allegiant Air, an American low-cost airline and subsidiary of Allegiant Travel Company. Founded in 1997 by Maurice J. Gallagher, Jr., the carrier began operations in 1998 and concentrates on leisure travel. Headquartered in Summerlin, Nevada, near Las Vegas, Allegiant operates a point-to-point network that serves many U.S. vacation destinations from a limited set of bases. The airline’s fleet consists of Airbus narrow-body aircraft, including the A319, A320, and A321. Its IATA code is G4, ICAO code AAY, and its callsign is ALLEGIANT. Allegiant markets low base fares with optional add-ons such as checked bags, seat selection, and hotel or car rentals, reflecting its ultra-low-cost carrier model. The company emphasizes direct-to-consumer sales and routes often oriented toward holiday periods and tourist destinations rather than major business hubs.

Allegiant can also refer to Allegiant, a 2013 dystopian novel by Veronica Roth. It is the third and final installment in the Divergent series, following Divergent (2011) and Insurgent (2012). The book continues the story of Tris Prior in a post-apocalyptic Chicago and the broader society’s fragmentation. Allegiant was published by Katherine Tegen Books and released in multiple formats. The novel was adapted into the feature film The Divergent Series: Allegiant, released in 2016, with plans for a two-part conclusion that were ultimately abandoned when the second film, Ascendant, was canceled by the studio.
