Boeing said on Wednesday that it has finalized an order for 60 of its planned 737 Max planes, pushing its total for the Max to more than 1,000.
The deal, which Boeing said was finalized with leasing company Aviation Capital Group in late December, would be worth $6 billion at list prices. Steep discounts are common on large orders, however.
The 737 is a workhorse of the world's airlines. Boeing decided in 2011 to make an updated version, the Max, with a new engine and other tweaks aimed at making the plane more fuel efficient. The first ones are expected to be delivered in 2017.
Aviation Capital Group has also ordered 30 A320neos, a competitor plane from Boeing's European rival Airbus.
The Newport Beach, Calif., company, a unit of life insurance, annuities and mutual funds provider Pacific LifeCorp, owns 240 commercial jets.
Shares of Boeing, which is based in Chicago, rose $1.39, or 1.8 percent, to $76.75 in premarket trading Wednesday. Stock futures rallied broadly after Congress ended a budget stalemate and averted the "fiscal cliff."
