Aviation Capital Group (ACG) has finalized a landmark firm order for 50 Boeing 737 MAX jets, significantly expanding its narrowbody portfolio.
The agreement, announced Jan. 13, 2026, includes an even split of 25 737-8 and 25 737-10 aircraft, the latter being the largest and most fuel-efficient variant of the MAX family.
The deal catapults ACG to the top position among aircraft lessors for the 737-10, with a total of 50 firm orders for the variant.
In aggregate, ACG's 737 MAX order book now stands at 121 aircraft.
Boeing (NYSE:BA) confirmed that this latest commitment secures critical delivery slots ranging from 2026 through 2033, ensuring ACG can meet the sustained demand for high-capacity, short-to-medium-haul jets.
The order underscores the central role of aircraft lessors in the current aerospace landscape.
Leasing firms have now ordered nearly 1,300 737 MAX jets, representing approximately 20% of the total 737 MAX backlog.
This trend highlights a strategic shift by airlines to preserve capital through leasing while modernizing fleets with newer, more efficient technology that reduces fuel consumption and carbon emissions by roughly 20% compared to previous generations.
As of late 2025, ACG reported a robust fleet of approximately 470 owned, managed, and committed aircraft.
The company, a wholly owned subsidiary of Tokyo Century Corporation, currently serves roughly 90 airlines across 50 countries, positioning itself as a primary beneficiary of the global post-pandemic recovery in air travel.
