Just wandering over from the neighbouring CX board.

Virazuno did you have one boarding pass (SIN-HKG) or two (SIN-BKK, BKK-HKG)?
Years back- having done my fair share of CX 1-stops via BKK (they used to have a lot more such flights), and in cahoots with a competent HKG based TA, I did manage, once, to get the miles corresponding to HKG-BKK-XXX, rather than HKG-XXX. The sectors showed up separate in Manage My Booking on CX, and I selected different seats on purpose..got 2 boarding passes while checking in ..vague memories of an announcement to the effect “Paging passenger jagmeets, if you’re on board, please identify yourself to a crew member”, but I may be mistaken.
