thanks Swanhunter. Great read ^
Delays on the PVG-HKG route of 1-3 hours are so common! And the process is exactly as you describe. Food on ground, inflight magazine, duty free magazine, crappy tv on fold-down monitor
sans sound, then... time for take-off... and another 2.5 hours with nothing to do.
It can be one of the most boring flights in the world!
Only once in the dozens of times I have taken the flight did we board in HKG, actually push back 15 mins early, and arrive in PVG 30 mins before schedule. It was weird. No-one knew what to do
