Brief History
IndiGo was founded on August 4, 2006, by InterGlobe Enterprises (Rahul Bhatia, 38% stake) and Caelum Investments (Rakesh Gangwal, later reduced stake), with a $1.1B order for 100 Airbus A320s. Operations began on August 4, 2006, with a Delhi–Imphal flight, focusing on metro-to-metro routes. By 2011, it launched international services (Dubai, Bangkok) and went public on NSE (November 2015), raising ₹3,010 crore.
The 2010s saw explosive growth: Ordered 180 A320neos (2011, largest single order then), followed by 250 A320neos (2015, $26.5B). Reached 1 million monthly passengers by 2013; became India’s largest airline by market share (2014). Acquired ATR 72-600s (2017) for regional routes via InterGlobe Air Transport. Expanded to 50+ destinations by 2018, with first A321neo delivery (2018) and long-haul trials (e.g., Istanbul, 2019).
COVID-19 disrupted 2020–2021, with ₹5,806 crore losses (FY2021). Recovery began in 2022, achieving profitability by FY2023 (₹4,500 crore profit). Challenges included Pratt & Whitney engine issues (75 aircraft grounded 2023–2024) and a 2021 data breach (resolved, no financial impact). In 2024, IndiGo ordered 500 A320neo-family aircraft and 30 A350-900s, marking its long-haul pivot. Co-founder Gangwal exited the board (2022), with Bhatia consolidating control.
By September 2025, IndiGo operates 426 aircraft, with 104 million passengers carried in 2024. Recent milestones: Codeshare expansions (Etihad, 2024), hotel booking platform (2025), and plans for A350-900 operations (2027, targeting London, New York). Despite engine challenges, IndiGo maintains leadership with a 60% domestic share and growing international presence.
