Avolon Aerospace Leasing and Boeing have finalised an order for 15 737 Max and 10 737-800NG aircraft.
The 737 Max order consists of 10 737-8s and five 737-9s.
The order was first announced as a commitment at the Farnborough Airshow in July and has a list price value of $2.4 billion, says Boeing.
"Our customers are always looking for more fuel-efficient airplanes," says John Higgins, president and chief commercial officer for Avolon.
"The 737 Max will provide the fuel efficiency and operating economics airlines need to be successful. The 737 Max is in high demand worldwide and securing valuable, attractive positions early in the Max program ideally positions Avolon to best serve our growing global customer base."
Boeing says that with this deal, it has 664 orders for the 737 Max from seven customers.
