Irish aircraft lessor Avolon has finalised a firm order for 140 Boeing 737-10s, confirming the variant of a 737 MAX purchase first announced in October. Boeing describes it as the largest 737 MAX order placed by a lessor. The deal takes Avolon’s unfilled Boeing 737 backlog to more than 240 aircraft, although no delivery schedule, customer allocation or order value was disclosed.
Avolon’s October order for 140 Boeing aircraft formed part of broader commitments for 250 new-technology aircraft from Boeing and Airbus. The Boeing portion was then identified only as 737 MAX aircraft. Avolon’s third-quarter update had said the commitments were subject to approval by Bohai Leasing, its 70% shareholder; the finalised purchase confirms the Boeing order has progressed.
The 737-10 is the largest member of the MAX family. Boeing lists capacity of up to 230 passengers and a range of 3,100 nautical miles (5,740 km). Avolon chief executive Andy Cronin cited demand for newer aircraft, the variant’s capacity and economics, and the lessor’s aim to support airline growth and fleet renewal. Boeing also reported that lessors placed firm orders for more than 230 737-10s in 2026 and have ordered more than 1,450 aircraft across the MAX family.
