I'm flying CX888 HKG-YVR-JFK soon and the loads are F4 A2 J7 C0 D0 Y0.....
Much as I am hoping for an operational upgrade to J from my spendy

M fare ticket, I'm curious about how CX goes about bumping pax off the aircraft if it's really full.
What sort of compensation do they offer? How much negotiating power do I have as far as choosing the airline to which I am bumped if there isn't another CX flight for me? Would they move me up to J if they bumped me as often happens on airlines in the States?
Thanks!
