Chinese aircraft leasing company Bohai Capital said on Sunday its Avolon Aerospace Leasing Ltd subsidiary had agreed to buy 55 B737 MAX 8 and 20 B737 MAX 10 aircraft from Boeing, and may order an additional 20 M737 MAX 8, with a total list value of around $11 billion. Bohai's Avolon, part of aviation-to-shipping conglomerate HNA Group, had signed a memorandum of understanding at the Paris Airshow in June for 75 Boeing 737 MAX 8 aircraft and said it was considering Boeing's 737 MAX 10 models.
