New Delhi, India: IndiGo has signed a Memorandum of Understanding (MoU) with CFM International for more than 1,000 LEAP-1A engines to power 510 Airbus A320neo Family aircraft, marking the largest single LEAP engine order in CFM International’s history.
The agreement, announced on July 20, 2026, at the Farnborough air show, also includes CFM’s support for establishing IndiGo’s upcoming engine maintenance, repair and overhaul (MRO) facility in India. The partnership will further provide long-term material services, including spare-parts supply, as IndiGo expands its fleet and operations. According to CFM, the arrangements are intended to support high dispatch reliability, predictable costs and continued operational support as the airline scales up.
The deal comes as IndiGo accelerates its long-term fleet expansion. The airline currently has more than 430 aircraft and operates approximately 2,200 daily flights to more than 95 domestic and 45 international destinations. It welcomed more than 123 million customers in FY2026. Its existing A320/321 Family fleet has already crossed 375 aircraft, while the airline’s broader aircraft order book is close to 1,000 aircraft. IndiGo has also stated its ambition to double its fleet by 2030.
Willie Walsh, Chief Executive Officer Designate of IndiGo, said the agreement extends the airline’s long-standing partnership with CFM as it moves into its next phase of growth and seeks to become a truly global carrier. He said CFM has supported IndiGo’s expansion since 2016 and described the LEAP engine’s proven reliability as a key factor in supporting the airline’s scale, operational resilience and sustainability objectives.
IndiGo’s relationship with CFM dates back a decade. In 2016, the airline operated Airbus A320ceo Family aircraft powered by CFM56-5B engines. In 2019, it expanded the partnership by selecting LEAP-1A engines for its Airbus A320/321neo Family fleet.
The latest agreement also strengthens CFM’s position in India’s rapidly expanding aviation market. India is CFM’s third-largest market, with five Indian airlines operating more than 400 LEAP-powered aircraft and another 2,000 engines on order.
H. Lawrence Culp Jr., Chairman and Chief Executive Officer of GE Aerospace, said LEAP engines are now delivering up to twice the time on wing in hot and harsh operating environments compared with when the engine first entered service, while maintaining fuel efficiency and reliability. He added that GE Aerospace has more than 40 years of experience supporting India’s aviation sector, with manufacturing operations in Pune, a local supplier network and advanced engineering capabilities in Bengaluru.
For Safran, the agreement further underlines India’s importance as one of the world’s fastest-growing aviation markets. Safran Chief Executive Officer Olivier Andriès said the company’s investments in India, particularly in LEAP engine production and MRO capabilities, are aimed at supporting IndiGo’s growth while contributing to the development of the country’s aerospace industry.
The planned IndiGo MRO capability comes amid a broader expansion of LEAP maintenance infrastructure. Safran last year inaugurated its largest LEAP engine MRO centre, a 45,000-square-metre facility that is expected to eventually handle up to 300 LEAP shop visits annually and feature a next-generation test bench.
CFM said more than 10,000 LEAP engines have been delivered to date, making the programme the fastest ramp-up in commercial aviation history. The company continues to introduce upgrades, including a high-pressure turbine (HPT) durability kit designed to extend time on wing and a reverse bleed system (RBS) aimed at reducing airline maintenance requirements.
The Times of India reported that the list price of a LEAP-1A engine is around $14.5 million, which would put the theoretical list-price value of more than 1,000 engines at above $14.5 billion. However, actual transaction values are generally not disclosed because engine pricing varies between customers and agreements.
CFM International is a 50:50 joint venture between GE Aerospace and Safran Aircraft Engines. The company produces the LEAP family of engines and supports LEAP and CFM56 fleets worldwide. The partnership is also developing the RISE programme, which is focused on next-generation propulsion technologies for future commercial aircraft.
For IndiGo, the agreement represents more than a major engine procurement. The combination of a record LEAP-1A commitment, long-term material support and plans for expanded MRO capabilities in India gives the airline a broader support structure for its next phase of fleet growth. It also reflects the increasing scale of India’s commercial aviation market and the growing role of local maintenance and aerospace infrastructure in supporting the country’s expanding airline fleets.
