Through ongoing fleet augmentation and replacement, which is slowed by constraints in the supply chain at the moment, it is able to maintain a young fleet of fuel-efficient planes thanks to its large orders.
Nearly 1,000 Airbus A320neo (new engine option), Airbus A321neo (extra-long range), and Airbus A321XLR (extra-long range) aircraft are in IndiGo's order book. We have the flexibility to choose between a mix of A320/321neo and A321XLRs as we approach the end of this decade, depending on demand then, because we have placed this order so far in advance. Additionally, it assists us in preparing for the fleet expansion in all aspects, including pilots,” Elbers stated.
In February, Air India placed an order for 470 Boeing and Airbus aircraft, including A350s, Boeing 787s, and B777X at a list price of $70 billion, with 400 single-aisle aircraft and 70 wide-body aircraft. All single-aisle aircraft are currently in IndiGo's order book, and the airline has not eliminated the possibility of including widebodies in its fleet. Two Turkish Airlines widebodies have been wet leased—hired with operating crew—and are currently operating on the Delhi-Istanbul and Mumbai-Istanbul routes.
Pratt & Whitney and CFM are options for the engines, which IndiGo will select "in due course" along with an "exact mix of A320 and A321 aircraft." Additionally, Boeing had made a persuasive case for its single-aisle B737MAX. “Indigo will be able to maintain its strong focus on lowering operating costs and delivering fuel efficiency with the fuel-efficient A320neo family aircraft,” the airline stated.
