Storms, air controls delay flights in east and central China

China's major airlines on Sunday announced adjustments or cancellations of a few flights after severe weather and air traffic controls caused massive delays in eastern and central China.
China Eastern Airlines said some flights in Nanjing and Shanghai are likely to be delayed or canceled in the next few days.
Another company, China Southern Airlines, said flights from Shanghai to Xiamen, Fuzhou, Taiwan and some central and southern regions are likely to be affected on Sunday, with the capacity of some airways in Shanghai dropping by 30 percent.
China's airline regulator has issued an orange alert for massive flight delays in eastern and central regions due to "rainstorms, routine military exercises and other comprehensive factors."
