No, the base salary plus HDP is contractual. Much like at BA, there is significant chunk of change above the basic pay point.
McNugget any relation to the famous SO with a similar name ?
Whilst HDP is contractual, you cannot bank on it. You have little control over how many hours you will get each month, and since they are hiring onto on the Freighter and A330 you will not be doing 84 hours a months, less. Much less especially at the start. Most Airbus and Freighter pilots never see overtime.

There is no "pension", and due to changes in legislation that money is locked up for a long time even if you resign.
HKPA/Education etc are all subject to "policy" changes. Allowances at outports are rumored to be taken away shortly, they are not contractual. 13th month (there are 52/4=13 4 week blocks i.e. "months" per year). The company may pay you for 48 weeks or 52 weeks depending on how they feel.
Go back 20, 15, 10 year ago to see how much they have cut to see the direction things have moved.
Look at the high inflation rate, CX wages in real terms have gone backwards 10-20% in the last 5 years. Try getting kids into school, some are demanding 4 million dollar debentures to get your kid in. Have fun getting a slot if you did not put their name down the day after they were born.
