You must be on the 777! The long haul to North America and Europe on the airbus is all HKG based pilots since there are no pilots based in either of those locations!
Personally I wouldn't worry about the situation you described as the majority of us are in HK and the base numbers are so so small by comparison I don't think a situation such as that would happen, also at the moment the only people flying are a select group of HKG based guys so we have no fear of any based pilot being used to stop us from all
flying above minimum! When things pick up again we will all be so busy as the company shrinks, especially after the next round of layoffs
