Delta announces order for 200 LEAP-1B engines to power new fleet of Boeing 737-10 aircraft


  • CFM selection continues longstanding relationship that spans more than 40 years

FARNBOROUGH, England –18 July 2022 – Delta Air Lines has ordered 200 CFM International LEAP-1B engines to power its new fleet of Boeing 737-10 aircraft announced earlier today. The order also includes additional spare engines and an option to purchase up to 60 additional engines.

“These next-generation engines offer advantages in terms of fuel efficiency, reliability, and daily utilization that are central to our ongoing effort to streamline and elevate Delta’s fleet,” said Mahendra Nair, S.V.P. - Fleet & TechOps Supply Chain at Delta Air Lines. “We’re grateful for our longstanding relationship with CFM that made this agreement possible.”

Delta was the first operator to put a CFM  engine into service on April 24, 1982, with the first commercial flight of a CFM56-2-powered first McDonnell Douglas DC-8-71 aircraft between Atlanta and Savannah, Georgia.  The airline has continuously operated CFM engines ever since.   The airline  currently operates more than 440 CFM-powered aircraft.

"We are delighted to have the opportunity to bring all of the benefits of the LEAP engine to Delta Air Lines’ new fleet," said Gaël Méheust, president and CEO of CFM International. "Our customers are seeing 15 to 20 percent better fuel efficiency, which translates to an equivalent reduction in CO2 emissions; and it has the highest reliability and daily utilization rates in this thrust class.  We believe the LEAP-powered 737-10 will prove to be a real asset to Delta’s operations."

Since entering service, the LEAP-1B engine has accumulated five million engine flight hours and 1.9 million cycles.

The advanced CFM LEAP engine continues to set new industry standards for fuel efficiency and asset utilization, logging 20 million engine flight hours in commercial operation. The fleet is providing 15 to 20 percent better fuel consumption and lower CO2 emissions, as well as a significant improvement in noise compared to previous generation engines. Since its entry into service in 2016, the LEAP engine allowed our customers to save more than 14 million tons of CO2.
