Avolon has signed its previously announced order for 140 Boeing 737 MAX aircraft and revealed that every jet in the deal is a MAX 10. The purchase is the largest 737 MAX order ever placed by an aircraft leasing company.
The Irish lessor announced the agreement on October 9 but did not disclose which MAX variants it had selected. The purchase was also subject to approval by shareholders of Bohai Leasing, the Chinese company that owns 70% of Avolon.

Boeing confirmed on Wednesday, November 4, that the deal has now been signed and disclosed its composition for the first time: all 140 aircraft are MAX 10s.
The revelation comes only two weeks after the Federal Aviation Administration (FAA) certified the 737 MAX 10 on October 20, after years of delays to the program.
Avolon becomes major MAX 10 customer
The 140-aircraft purchase places Avolon among the largest identified customers for the MAX 10, behind only United Airlines, with firm orders for 167 aircraft, and Ryanair, with 150.
It is particularly significant in the leasing market. Boeing says lessors have placed firm orders for more than 230 MAX 10s in 2026, compared with fewer than 50 aircraft on backlog at the end of last year.

Avolon already had substantial commitments to the 737 MAX before the October agreement. It ordered 40 MAX 8s at the Paris Air Show in 2023 and another 40 MAX aircraft later that year, with the second batch split between the MAX 8 and MAX 10.
The latest agreement takes Avolon's total backlog across the 737 MAX family to more than 240 aircraft.
Largest member of MAX family
The 737 MAX 10, also designated 737-10 by Boeing, is the largest version of the manufacturer's current single-aisle family. It can carry up to 230 passengers in a high-density configuration and has a range of 3,100 nm (5,740 km).
Its size puts it in direct competition with the Airbus A321neo, although the Airbus model offers greater range and has accumulated a substantially larger order book.
Certification had been one of the main uncertainties surrounding the MAX 10. Boeing unveiled the aircraft in 2017, but its approval suffered repeated delays as the manufacturer and the FAA worked through certification requirements introduced after the MAX 8 accidents.
FAA approval last month cleared the MAX 10 for deliveries. The first aircraft is expected to be handed over in the first quarter of 2027 by lessor Aviation Capital Group (ACG) to Canadian carrier WestJet. Boeing already has several MAX 10s built and awaiting delivery.
At the time of certification, Boeing said more than 30 customers had ordered 1,555 aircraft of the variant, equivalent to more than 30% of the outstanding 737 MAX backlog.
The 140 Boeing aircraft were part of a much larger round of orders announced by Avolon in October. The lessor also ordered 110 Airbus jets: 75 A320neo family aircraft and 35 A330neos, plus options for another 100 Airbus aircraft.
