The Beijing Daxing Airport, 42 miles south of the Chinese capital, was constructed beginning in 2014 under President Xi Jinping. The Beijing Capital International Airport had the second-highest total passenger traffic in 2016, just short of the number for Hartsfield-Jackson Atlanta International Airport. Daxing is said to be able to initially serve 45 million passengers annually and to eventually support 100 million passengers each year. The airport is scheduled to open in 2019.
