Chairman Murat Şeker announced plans to order approximately 420 aircraft from Boeing and Airbus over the next decade. This strategy aims to increase available seat kilometers by 6%, focusing on higher flight frequencies on existing routes—particularly long-haul flights to South America and East Asia—while planning to add roughly 30 new cities to its network over 20 years. The plan also emphasizes cabin innovation, such as the Crystal Business Class suite. In a related development regarding fleet diversification, the airline has signed an agreement with AerCap to lease two Boeing 777-300ERSF freighter aircraft. These planes will undergo conversion from passenger to cargo models at the Etihad Engineering facility in Abu Dhabi, utilizing technical development from Israel Aerospace Industries. The aircraft are expected to be delivered between March and September 2027. ## Timeline ### 2026-10-29: Turkish Airlines to lease two Boeing 777 cargo aircraft Turkish Airlines will lease two Boeing 777 cargo aircraft from AerCap, with conversions being handled by Etihad Engineering using Israeli-developed technology. 3 sources. https://clstr.news/cluster/turkish-airlines-to-lease-two-boeing-777-cargo-aircraft ### 2026-10-26: Turkish Airlines announces 420-aircraft growth strategy Turkish Airlines Chairman Murat Şeker announced a plan to order 420 aircraft from Boeing and Airbus, targeting a 6% capacity increase and enhanced cabin products like Crystal Business Class. 2 sources. https://clstr.news/cluster/turkish-airlines-announces-420-aircraft-growth-strategy --- Cite as: Turkish Airlines expansion and fleet modernization.
