Did you check the loads on Cupid? If Y was showing red then it would most likely have been over sold by a substantial amount. Cupid, unlike Travel Desk will tell you by how much. Was Travel desk also showing red overall? Usually well before check in the CX check in supervisors would have decided which Y class passengers would be upgraded, i.e. frequent flyers, Marco Polo etc. Having only recently travelled to Sydney myself, most flights were overbooked overall. I’m not sure though how many “No Shows” there were though in the end.
All that being said, I’m not sure how this will play out after the 12th?
