The aviation industry in India is highly growing and is expected to become the third largest aviation market by 2020. Key reasons for its growth include the expansion of low-cost carriers, modernization of airports, increases in foreign direct investment and advances in information technology. Currently, Indigo has the largest market share at around 40% and the top 4 airlines (Indigo, Jet Airways, Air India, and SpiceJet) combine for over 80% of the market. The government is taking steps like opening more regional routes and smaller airports to further develop the industry.
