Indian budget carrier IndiGo has placed a firm order for 300 Airbus A320neo-family jets – a mix of A320neos, A321neos and A321XLRs.

The deal, described by the airframer as "one of Airbus's largest aircraft orders ever with a single airline operator", brings IndiGo's A320neo-family total to 730.

Cirium fleets data shows that the airline has 90 A320neos and seven A321neos in service, and already had another 190 A320neos and 143 A321neos on order.

IndiGos chief executive Ronojoy Dutta says the aircraft will enable the carrier to strengthen connectivity within India, with knock-on benefits for the country's economic growth.

"India is expected to continue with its strong aviation growth and we are well on our way to build the world's best air transportation system, to serve more customers and deliver on our promise of providing low fares and a courteous, hassle-free experience to them," he states.

Airbus chief commercial officer Christian Scherer asserts that IndiGo has "brilliantly demonstrated the relevance of the A320neo for leading low-cost operators", and that "the A321neo – and now the A321XLR – provide our operators with the logical next step in cost efficiency, passenger comfort and market coverage".

IndiGo operates 1,500 daily flights, serving 60 domestic and 23 international locations, Airbus notes.
