InterGlobe Aviation Limited was founded in 2006 by Rahul Bhatia and Rakesh Gangwal with the vision of providing affordable air travel to Indian consumers. The company launched IndiGo operations in August 2006 with flights between Delhi and Bangalore, introducing the low-cost carrier model to India's aviation market. This business model focused on operational efficiency, point-to-point routes, and competitive pricing.
IndiGo's early years saw rapid expansion across India's domestic routes. The airline quickly gained market share by offering reliable service at competitive prices, appealing to India's growing middle class and business travelers. The company expanded its fleet significantly, operating modern Airbus A320 aircraft and establishing a reputation for punctuality and efficiency.
In 2015, InterGlobe Aviation Limited went public with an initial public offering on Indian stock exchanges, allowing public investors to own shares in the company. This capital infusion enabled further expansion and modernization of IndiGo's fleet and operations. The IPO was successful, reflecting strong investor confidence in the company's business model and growth prospects.
Throughout the 2010s and 2020s, IndiGo expanded internationally, launching international routes to Southeast Asia, the Middle East, and other regions. The airline became India's largest carrier by passenger numbers and market share, establishing itself as a major player in Asia's aviation sector. InterGlobe Aviation continued to invest in fleet modernization and technology infrastructure.
