I wouldn't panic just yet, there are always rumours of some sort floating around, personally I don't see CX moving unless the Chinese government decide that they want CA to buy out Swire ( and I don't expect that any time soon).

I have to admit though, that as a *A fan I would be quite happy to do a swap and take CX off your hands and add exciting Hong Kong as a *A hub and let you have the over-rated SQ together within it's dull squeaky clean home SIN ( if ever a three letter code was misapplied to a destination surely it is this one)
