Multiple flights to and from the Chengdu Shuangliu International Airport in central China were canceled or delayed, while many were forced to land at other airports, China's Xinhua news agency reported, calling it "the worst fog to hit the ... city in years."
Images from China Central Television (CCTV) showed weary passengers asleep in their airport seats and others eating instant pot noodles, while crates of luggage sat on the tarmac next to grounded planes.
