I was at a pub in HK a few months ago and happened to hear a few CX pilots griping about the job, basically the same stuff you hear everywhere these days about cost of living, schools too expensive, rosters, etc. I don't work at CX and I don't want to discount whatever is going on there but based on what I heard said that day there is little improvement to be had at any ME carrier. Unless you are from the EU and absolutely must commute home more often, or hell bent on flying a 380 you are probably better off where you are.
CX isn't the only carrier in HKG, i am sure plenty of disgruntled guys at HKA and even other carriers in SE Asia will be showing up. Some of the PFT kids flying 320s for the usual suspects are probably ready to join Club 380.
