Turkish Airlines has initiated a significant fleet expansion and technical development program centered on the Boeing 737 MAX aircraft.

In late September 2026, the carrier finalized an agreement with Boeing to acquire up to 150 Boeing 737 MAX jets, consisting of 100 firm orders for the 737-8 model and 50 options. This order aims to strengthen short- and medium-haul networks while reducing fuel consumption and emissions by approximately 20%.

In October 2026, the airline expanded its technical strategy through a major agreement with CFM International. While initial reports indicated a Memorandum of Understanding for up to 295 LEAP-1B engines to support the new and existing fleet, subsequent details revealed a larger multi-billion dollar deal to acquire more than 600 LEAP-1B engines. This procurement covers the airline’s entire engine inventory, including spare units and those for leased aircraft, supporting both the main carrier and its subsidiary, AJet.

A central component of this partnership is the establishment of an engine maintenance, repair, and overhaul (MRO) facility within Turkish Technic (Teknik A. Ş.). CFM International will provide the necessary licenses and support to develop advanced module and part repair capabilities in Turkey. This facility is intended to expand the country’s capabilities in next-generation engine maintenance and strengthen its position within the global aviation industry, with the potential to eventually serve other airlines.
