Housing
Tony, the old expat housing has gone under the new contract and was replaced by a special allowance of $20k a month which is still there.
I'm not sure that final DEFO interviews have been done in HKG before but expect to be asked questions about your current aircraft, they are not impressed if you don't know about what you fly now!
They are said to be looking for 40+ DEFOs so the odds are good. KA is a good airline with high standards (too high for some) and of course there is no bond and you get an Airbus rating out of it. If you are without a job now then it is well worth giving it a go.
