Turkish Airlines has finalized an order for up to 150 Boeing 737 MAX aircraft, the carrier announced, in what it described as the largest single-aisle jet order it has placed with the American manufacturer to date.
The agreement, reached after talks that began in 2025, was signed in the presence of Turkish President Recep Tayyip Erdogan. The airline said the deal is intended to reinforce its short- and medium-haul flight network and support its long-term fleet growth strategy.
The order includes 100 firm Boeing 737-8 jets, with an option for 50 additional 737 MAX aircraft. The agreement also gives Turkish Airlines the ability to shift some of the order toward the Boeing 737-10, the largest variant in the 737 MAX family, a provision the airline said would let it adjust fleet capacity more flexibly according to passenger demand and operational needs across its network.
Turkish Airlines said the new jets are expected to strengthen short- and medium-haul operations on both domestic and international routes where demand is particularly high.
The airline cited the 737-8's range and payload advantages, along with a fuel consumption and emissions reduction of about 20 percent, as factors that would help it meet operational needs while expanding its fleet and network.
Turkish Airlines and its low-cost affiliate AJet currently operate more than 200 Boeing aircraft, including 737 MAX, 737 Next-Generation, 787 Dreamliner, 777 and 777 Freighter models. The new order follows a purchase of 75 Boeing 787 Dreamliners placed in 2025, further extending the airline's longstanding relationship with Boeing.
Beyond the aircraft order, Turkish Airlines and Boeing are continuing broader cooperation tied to Türkiye's aviation ecosystem.
The two companies signed a strategic memorandum of understanding this year on industrial participation, establishing a cooperation framework built around three areas: capability development, value creation and business opportunities.
The framework is aimed at developing technical capabilities, sharing technology and expertise, supporting workforce development and strengthening sustainability efforts, as well as creating new industrial cooperation opportunities.
Turkish Airlines said that alongside the aircraft order, the industrial participation framework reflects Boeing's long-term commitment to supporting Türkiye's aviation ecosystem and extends the companies' cooperation beyond fleet expansion.
Murat Seker, chairman of the board and executive committee of Turkish Airlines, said the agreement represents an important step in the carrier's fleet growth strategy.
"The new Boeing 737 MAX aircraft will bring greater efficiency and flexibility to our operations, supporting our extensive flight network from our hub in Istanbul," Seker said, adding that the deal, which also benefits Türkiye's aviation ecosystem, reflects the airline's pleasure in extending its long-standing cooperation with Boeing.
Stephanie Pope, president and chief executive officer of Boeing Commercial Airplanes, said the order reflects the mutual trust and shared vision that have shaped the companies' longstanding partnership.
"We are proud to continue supporting Turkish Airlines and Türkiye's aviation ecosystem as they grow their Istanbul-based network, connecting more people to more destinations around the world," Pope said.
Boeing introduced the 737 MAX as an updated, more fuel-efficient version of its long-running 737 narrow-body family, and the jet has since become one of the best-selling aircraft in the manufacturer's lineup.
