What IndiGo filed
IndiGo disclosed to the exchanges a press release announcing a Memorandum of Understanding (MoU) with CFM International for an order of more than 1,000 LEAP-1A engines to power 510 Airbus A320neo Family aircraft. Per the filing, this would be the largest single order ever placed for LEAP engines and a record for CFM International.
The disclosure is at the MoU stage — the company describes it as "paving the way to a record agreement" rather than a concluded firm order. The announcement was made at Farnborough.
Beyond the engines: MRO and long-term support
The filing states the MoU extends past the engine purchase. It includes CFM's support in establishing IndiGo's upcoming engine maintenance, repair and overhaul (MRO) facility, and a long-term material services agreement covering spare-parts supply. IndiGo frames these as supporting dispatch reliability and predictable costs as it scales.
The company noted its relationship with CFM dates to 2016, when it operated A320ceo aircraft on CFM56-5B engines, and that it first ordered LEAP-1A engines in 2019 for its neo fleet. IndiGo describes CFM as a partner across a decade of growth.
Context from the filing
IndiGo characterises the deal as part of its "next phase of growth towards becoming a truly global airline." The filing describes a current fleet of 430+ aircraft operating roughly 2,200 daily flights across 95+ domestic and 45+ international destinations, and states the airline welcomed more than 123 million customers in FY26.
Because the agreement is described as an MoU, commercial terms such as the order value and delivery schedule are not disclosed in the filing.
