Boeing and Turkish Airlines on Wednesday announced a finalised order for up to 150 737 MAX airplanes, concluding talks that began in 2025, the US planemaker said.

According to a Boeing press release, Turkish President Recep Tayyip Erdogan attended the deal's conclusion.

Turkish Airlines has bought 100 737-8 jets and secured options for 50 more 737 MAX aircraft. Boeing described it as the airline's largest single-aisle order from the manufacturer.

The agreement includes substitution rights for the 737-10, the largest variant of the 737 MAX family, allowing the airline to switch some of the aircraft to the bigger model to carry more passengers on more routes.

"This agreement marks another significant step in the continued expansion of our fleet," said Murat Seker, chairman of the board and the executive committee of Turkish Airlines.

"The new Boeing 737 MAX aircraft will bring greater efficiency and flexibility to our operations, supporting the extensive network we serve from our hub in Istanbul," he said.

Seker added that the deal also supports Turkey's aviation ecosystem.

Stephanie Pope, president and CEO of Boeing Commercial Airplanes, said the order "reflects the trust and shared vision that have defined our long-standing partnership with Turkish Airlines."

Boeing said Turkish Airlines, including its subsidiary AJet, operates more than 200 Boeing airplanes, including the 737 MAX, 787 Dreamliner, 777, 737 Next-Generation, and 777 Freighter models. The airline plans to use the 737-8 on high-demand domestic and international routes, the company said.

Boeing said the 737 MAX family cuts fuel use and emissions by 20 percent compared with the aircraft it replaces.

The new order follows Turkish Airlines' 2025 purchase of up to 75 787 Dreamliners. Boeing said the latest agreement also comes with industrial participation, under which it will continue to support the Turkish aviation sector.

The press release did not disclose the financial value of the deal or a delivery schedule.

Founded in 1933 with five aircraft, Turkish Airlines is a member of the Star Alliance. It operates a fleet of 567 passenger and cargo aircraft serving 358 destinations in 133 countries, according to the release.
