I find this really interesting, and about time the rules were enforced. I don’t think I have taken a flight in recent memory where the somebody has not been using their phone during take off or landing. The only strange thing with rules in China is that they will not allow a mobile phone to be used in Airplane Mode, yet a cellular based iPad in Airplane Mode draws no attention.
It turns out that China was actually serious when it warned passengers against using phones on planes last year. Shockingly serious, in fact.
