A RED alert that had been warning of “specially severe” disruption to flights at Shanghai’s two airports was downgraded to the second highest level yesterday afternoon.

This was due to “cooperation and good management” between military and civil aviation regulators, China’s air traffic regulator said.

The alert became orange at 3:30pm. Previously, the Civil Aviation Administration of China had said there would be a 75 percent reduction of capacity at Hongqiao and Pudong airports between 2pm and 6pm.
