From 2017.10.01 to 2017.10.08.10 it is Golden Week in China. It means almost all activites are put to a hold. The time up to Golden Week is expected to be extremely busy. After Golden Week it normally takes a littel time before all systems are back to normal so some turbulence must be expected.
Hong Kong is closed 2017.10.01 - 2017.10.02. and 2017.10.05.
