IndiGo Airlines is India's largest and most profitable airline, having made profits for five consecutive years while its competitors Jet and Spicejet have lost money. IndiGo utilizes several strategies to keep costs low and maximize profits, including operating a homogeneous fleet of Airbus A320 aircraft, focusing on short-haul domestic and international routes, quick turnaround times, and online ticket booking. These strategies have helped IndiGo achieve a 31.6% domestic market share in India and become the only profitable major airline in FY2015.
