According to SCMP:

A pilot moving to an airline across the border can expect a salary of up to US$280,000 (HK$2.2 million) a year after tax, a jump of about US$80,000 (HK$624,000).

I thought CX's salaries were too high compared to the competition, which is one reason they can justify cutting housing allowances. The article says itself "The airline said it was focused on implementing big changes to pilot pay as its cost structure was “out of line” with that of its competitors.".
