Allegiant Air is a famous American low-cost airline, under the umbrella of Allegiant Travel, founded in January 1997; it was transformed into a low-cost airline only after its bankruptcy and reorganization in 2005, when its business focus shifted to routes between smaller cities and tourist destinations that had been neglected by the big airlines.
