Airbus says IndiGo Airlines has committed to buying 180 Airbus A320 aircraft, 150 of which would be the updated A320neo version, according to published reports.
IndiGo would be the first customer for the A320neo, which Airbus plans to start delivering in 2016. The new version is slated to deliver 15 percent fuel savings through the use of newly designed engines and other improvements.
The deal would be the largest order in history by number of aircraft, according to Airbus. At list prices, the order would be worth $15.6 billion (€12 billion).
