Aircraft manufacturer, Airbus, announced that the company has signed a Memorandum of Understanding (MoU) with India's economy carrier Indigo for 180 eco-efficient Airbus A320 aircraft.

Airbus also stated that the consignment will be the largest single firm order number for large jets in commercial aviation history. Of the entire order, 150 will be A320neo aircraft and 30 will be A320s. This also makes IndiGo a launch customer for the A320neo.

This order positions IndiGo to take full advantage of the predicted growth in Indian air travel, said John Leahy, Chief Operating Officer Customers.

IndiGo, India's largest low-cost carrier has expanded immensely since its conception capitalizing mainly on the rising middle sect of the Indian society.

This order for industry leading fuel efficient aircraft will allow IndiGo to continue to offer low fares. Ordering more A320s was the natural choice to meet India's growing flying needs, said Rakesh Gangwal and Rahul Bhatia, co-founders of IndiGo.

Although the total cost of the acquisition, estimations in the market are as high as $15.6 billion thereby propelling IndiGo to the big league.
