Pegasus Airlines is a Turkish low-cost airline with bases at several Turkish airports.
In 1989 two businesses, Net and Silkar, partnered with Aer Lingus to create an inclusive tour charter airline called Pegasus Airlines and services were inaugurated in 1990. In Greek mythology, Pegasus was a winged horse sired by Poseidon, in his role as horse-god, and foaled by the Gorgon Medusa. After two years, Aer Lingus and Net sold their shares in the company in 1994 to Istanbul-based Yapi Kreditbank, making Pegasus a purely Turkish company. In 2005, ESAS Holdings purchased Pegasus Airlines. Two months later, the airline changed from a charter airline, to a low-cost airline. In 2012, Pegasus Airlines bought 49% of the Kyrgyz air company Air Manas. In 2013 the air company had operated its first flight under the brand name Pegasus Asia.
