IndiGo Airlines, has created history by making this huge record deal in Aviation sector. In order to acquire 180 Airbus aircraft of the 320-neo series, India's leading low cost carrier made a mind boggling deal with Airbus.

The planes will be delivered over a wide span of 9 years from 2016 - 2025. This deal will go down as the largest single order deal in the history of commercial aviation history, making IndiGo the launch customer for the A320-neo.

More efficient engines and large wing tip devices called Sharklets that are also capable of significant fuel savings of up to 15 percent are the few plus points of these new jets.

The fuel savings will add up to the saving thought and will be saving over 400,000 US gallons of fuel and up to 3,600 tonnes of CO2 annually per aircraft. Apart from these features, the new jets are less noisy and provide a double-digit reduction in NOx emissions.

The deal is valued at a whooping $15.6 billion and will allow Indigo to expand its fleet further within the low cost arena.
