Early media reports during September 2011 suggested that there could be up to 9 runways: 8 runways for civil aviation plus one runway dedicated to military usage.[8][10][12][17][18] It would replace Beijing Capital International Airport (which had 83 million passengers in 2013, second most in the world) as the main airport of Beijing and the largest in China and was being planned as a domestic-only airport. The airport was planned to be able to handle 120 to 200 million passengers a year, which, if capacity were fully used, would make it the world's busiest airport by passenger traffic, surpassing Hartsfield–Jackson Atlanta International Airport by far.[19]
