Key facts

Background

IndiGo was established in 2006 as the airline business of InterGlobe Enterprises, a travel and aviation services group founded by Rahul Bhatia. He partnered with Rakesh Gangwal, a former chief executive of US Airways, to launch the carrier. The airline positioned itself as a no-frills, on-time, low-cost carrier focused on the rapidly growing Indian aviation market.

From the outset, IndiGo placed large orders for the Airbus A320 family, enabling fleet uniformity, lower maintenance costs, and operational efficiency. The airline became known for its single-class cabin, quick turnarounds, and emphasis on punctuality.
