In general the rules are:

Y & B are upgradable to Europe
Y & B are upgradable to China (including HKG)
Y & B & M are upgradable to the rest of Asia

Not all B & M fares are upgradeable as I have discovered by personal experience I'm hoping that one of our NW employee's on this board will provide the real scoop on how to tell.
