(Yicai Global) Aug. 2 -- Xiamen Air, a carrier based in China’s southeastern coastal province of Fujian, announced this morning that it had changed some schedules of 30 flight today due to air traffic control. 

Most of the flights affected by the changes were from Fuzhou and Xiamen to some cities in northeastern China as well as some flights to Chongqing, Urumqi and Tianjin.

Some flights which usually use the southeast coastal air routes have switched to inland routes, according to Flightradar24 data.

Of the country’s major airports, the on-time departure rate at those in the southeastern cities of Xiamen, Fuzhou, Quanzhou, and Jieyang were the lowest as of 12 noon today, data from Flight Master showed.

Shares of most airport operators dropped today. Shenzhen Airport Group [SHE: 000089] fell 3.3 percent, and Guangzhou Baiyun International Airport [SHA: 600004] edged down 0.6 percent. Only Shanghai Airport Authority [SHA: 600009] rose, gaining 1.1 percent.
