At the end of the day, it's down to the airline where they fly (minus China where air routes are set - no matter how rough the chop maybe en route) so they calculate the risk. Some airlines are more risk averse than others, I guess, but at the end of the day, they won't knowingly put anyone in danger. Slightly different, I know, but I remember flying home from MEX on BA and them totally rerouting our flight to avoid some stormy weather out on the Mexican Gulf. It added a an hour onto our flight on the good old 744, but better safe than sorry. Interesting, that should it have been the case in China, you wouldn't be allowed to deviate.
