north american trips in reverse plus having to pay own accom in hk plus no allowances plus rostered as hot reserve by c.ctrl.
All wrong. Where did you get that?
Originate N America, either dct HKG or via ANC. One day (24 hours) in ANC, then to HKG. 24 hours in HKG then back to ANC or a local flight in the region (NRT, SIN or other) or reserve - all on the roster, published on the 16th of the preceding month. On arrival at "home base" 5 days clear of duty.
All accom in HKG provided for by CX at the Headland Hotel (at CX City) with S&T allowance, about USD90 per day, cash, in advance on arrival.
