United Airlines has ordered 150 Boeing 737s in a deal worth up to £9.5bn.
The order pushes the total number of 737s sold to more than 10,000.
United has bought 100 737 Max 9 planes and 50 Next Generation 737-900ERs, which Boeing claims are the most fuel-efficient and reliable single aisle aircraft in the market.
The 737-900 ERs will be delivered from late 2013 and the 737 Max 9 planes will arrive from 2018 onwards.
