The country’s largest airline, IndiGo, on Monday (July 20, 2026) announced it will place an order with CFM International for more than 1,000 engines to power its 510 A320 neo family planes.

IndiGo and CFM International, an equal joint venture between GE Aerospace and Safran Aircraft Engines, have inked a Memorandum of Understanding (MoU) for the order at the Farnborough International Airshow in the U.K.

The order for more than 1,000 LEAP-1A engines to power 510 Airbus A320 neo family aircraft will also be the “largest single order ever placed for LEAP engines and a record for CFM International,” a release said on Monday (July 20).

A320 neo family planes include A320 neos, A321 neos and A321 XLRs. All are narrow-body aircraft.

CFM International would also provide extensive support to the airline in establishing its engine MRO (Maintenance, Repair and Overhaul) facility in Bengaluru.

Besides, it will provide support to the IndiGo fleet through long-term material services agreement, including supply of spare parts.

Currently, IndiGo has an operational fleet of over 400 planes and over 900 Airbus aircraft are on order.

“CFM has been a trusted partner in our growth journey since 2016, supporting a fleet that now exceeds 375 A320/321Family aircraft. The LEAP engine’s industry-leading proven reliability makes it the ideal choice to support our scale, operational resilience and sustainability ambitions,” IndiGo CEO Designate Willie Walsh said.
