I flew CX317 PEK-HKG today, 2 August. We were delayed at our gate for 2 hours due to "airspace restriction" by Beijing ATC. I wasn't sitting near a window so didn't see if other planes were taking off/landing.
So my question is, did PEK have a airport-wise ground stop today this morning, or was that just affecting PEK-HKG routing?
I know during the Opening Ceremony of the Olympics, the Chinese government said that PEK airport would be shut down, but it's still almost a week away.
How often does this restriction happen; is it because of flow control or something? I had never come across this happening before. Also, the weather seemed good today too.
