The Indian airline market has an oligopolistic structure. There are currently 22 airlines operating in India, with the top domestic carriers being Air India, Jet Airways, IndiGo, Spice Jet, and GoAir. The Indian market is characterized by high barriers to entry due to the huge capital investments and limited government permits required to start an airline. It is estimated that India will become the third largest aviation market in the world by 2026 due to its growth potential in the industry.
