Dragonair is an excellent airline and always ranks in my top 5 of expat airlines to get hired by. They operate A320 and A330s from a Hong Kong base. They fly into mainland China and have recently started branching out with some outward international flying from Hong Kong as well.
I've found them to be a tough nut to crack though. They were my first choice of expat airlines for various reasons when I was looking for work ( Cathay had the recruitment ban at the time ). I speak Mandarin Chinese and have experience flying in the vicinity, yet couldn't get a reply out of them. Physically went to Hong Kong and arranged a meeting with Ann Law, one of their recruitment department people. Even though I had ample qualifications and speak the predominant language of the area they do most of their flying in, they sent me a letter a few weeks later to say I wasn't qualified.
As it turns out, Dragonair flight operations management have a view of the U.S. FAA certificate as a joke that you can easily pick up in a Cracker Jack box. They recruit primarily from Australia and the UK. So unless you have an Australian/NZ or European certificate you can pretty much forget going to work for Dragonair.
They do work you hard over there. One of our guys just went there and I remember him asking a former Dragonair skipper what kind of time off he had. The reply was, "not much".
