Boeing Co. said on Wednesday that it sold 10 of its big 777s to the airplane leasing arm of General Electric.
The order for the 777-300ERs would be worth $2.8 billion at list prices, although discounts are common.
Boeing spokesman Tim Bader said the order by GE Capital Aviation Services was all-new and had not been listed previously.
The new order means GECAS has ordered a total of 53 777s. Most have been delivered, though it is still waiting for three more 777-300ERs ordered in 2000, as well as two more 777 freighters ordered in 2006.
Before the latest order, Boeing had a total of 91 deliveries of the 777 pending.
The 777-300ER carries 365 passengers. Airlines use the plane on high-density, long-haul routes.
Boeing shares rose 31 cents to $73.93 in afternoon trading. General Electric Co. shares rose 30 cents to $20.16.
