China's Juneyao Airlines Co. says it is ordering 50 of Boeing's popular 737 single-aisle airliners for its 9 Air subsidiary.
Boeing confirmed the order is a mix of Next Generation 737s and 737 Max aircraft. The 737 Max, the first of which will enter airline service in 2017, is the latest model series of the 737, which had its origin in the 1960s. The Next Generation is the current model 737 now being delivered to customers.
The 737 Max will feature new engines, upgraded wings and aerodynamic improvements to bolster the 737's fuel economy.
Boeing didn't specify how many of each series of 737s the Chinese customer will buy. At its maximum, the order could amount to about $5 billion at list prices.
9 Air is a new discount carrier in China. The planes ordered this week will be built in Boeing's Renton factory where all 737s are manufactured.
