Economic growth is helping make air travel affordable to more Chinese, increasing demand for planes from carriers such as Air China and China Southern Airlines.
Boeing deliveries this year to China will be about 140 aircraft after handing over a record 143 planes last year, Marc Allen, the aircraft maker's China president, said in January.

Boeing, which delivered a record 648 jets worldwide, also secured orders for more than 230 new aircraft from the country last year, he said.
Carriers have taken advantage of low-cost financing to replace older models with newer, more efficient jets. Boeing's 1,355 net orders for 2013 was the second-highest annual sales tally, and an increase from the 1,338 a year earlier.

China Southern, the Guangzhou-based company that's Asia's biggest airline by passenger numbers, took deliveries of 37 aircraft last year, according to Boeing's website. That was the second-most among carriers worldwide, lagging behind only American Airlines's 39, according to the website.
