Pegasus Airlines finalizes agreement for CFM LEAP-1B engines to power Boeing 737-10 fleet

• Pegasus Airlines and CFM International have signed an agreement for up to 300 LEAP-1B engines to support Pegasus’ future Boeing 737-10 fleet.
• The agreement, which also covers spare engines and long-term maintenance services, supports Pegasus’ sustainable growth strategy with higher fuel efficiency and lower emissions goals, and will support aircraft deliveries under Pegasus Airlines’ largest aircraft order to date, announced in December 2024.

ISTANBUL, Türkiye / CINCINNATI, OH – December 18, 2025 – Pegasus Airlines and CFM International today announced an agreement for up to 300 LEAP-1B engines which will power the airline’s future Boeing 737-10 model fleet. The contract also includes spare engines and a long-term maintenance agreement.

“Since we launched operations in 1990, CFM engines have played a major role in helping Pegasus build a reliable, efficient fleet that serves our customers,” said Güliz Öztürk, CEO of Pegasus Airlines. “We have been extremely pleased with the operation of the LEAP engine family and look forward to bringing the same performance and stability to our Boeing 737-10 fleet. The lower emissions and higher fuel efficiency of LEAP-1B engines will significantly contribute to both our 2030 CO reduction target and the 2050 net-zero CO industry emissions goal.”

“This agreement marks a significant expansion in our very long and successful relationship with Pegasus and we look forward to providing the level of support that this airline has come to rely on from CFM,” said Gaël Méheust, president and chief executive officer, CFM International. “We believe that the LEAP-powered 737 MAX 10 will be an invaluable asset in Pegasus’ continuing expansion, providing longer range, lower emissions, better fuel efficiency, and unequalled reliability.”

The airline had become globally the first LEAP engine operator in July 2016, with the first commercial operation of these engines taking place on a Pegasus flight between Istanbul and Antalya. The airline began commercial operations with CFM56-3 engines and grew to include fleets powered by CFM56-5B and CFM56-7B engines. Pegasus now continues to expand with the latest generation of aircraft powered by both LEAP-1A and LEAP-1B engines. The average age of Pegasus’ fleet is 4.9 years, making it among the youngest in Türkiye and the second youngest globally. *

With more than 4,400 aircraft delivered to date, CFM LEAP engines have experienced the fastest ramp in commercial aviation history. Advanced technologies like composite fan blades and ceramic matrix composites deliver an engine that’s 15 percent more fuel efficient, with 15 percent lower carbon emissions than prior-generation CFM56 engines. Backed by advanced health monitoring systems and an open MRO ecosystem, CFM LEAP engines offer mature reliability and enable high asset utilization for narrowbody aircraft.

*Pegasus Airlines has the world's second youngest aircraft fleet among airlines with more than 100 aircraft, according to the ch-aviation Youngest Aircraft Fleet Award 2025.
