Change is hard once already set up somewhere. If it were easy, CX would be a ghost town. Yes, it’s hard to replace the money straight away, but it’s easy to improve one’s lifestyle outside of Hong Kong. Yes, other big cities are expensive too, but you don’t have to live in them to work from them. HK is a very difficult commute from anywhere, especially on a CX roster with so many changes and very expensive staff travel. This is far easier and less expensive at most, if not all, other airlines.
