Good Man
Glad to see you've been able to filter the information from your research. If you're working for KAL & Air Japan, you'll understand the cost of living issues in a city like HK.
Although commuting as an SO is not impossible, it's hard work. That only leaves living in HK without the expat package (not easy even for a young single person). Judging by your posts, you've been around the industry for a while, and have a family, so you're probably smart enough to make a sensible decision. Use that "self-respect" you have left and apply where your skills & experience will be properly valued.
