I arrived in CAN yesterday on CZ326 in J - after being rebooked by CX check-in staff.
I count my family
very lucky that we got this outcome, and was only possible as we were already at the airport.
Thank you
@kangarooflyer88 for the late-night help, and suggestion of just going to ground staff.
I'm not sure what the contractual terms are in this situation between airlines - QF ticketing staff at Syd T1 were only helpful if I kept asking questions - often diverting to "get a refund and buy tickets" or "No award availability", or "We can only rebook you on Oneworld", which ruled out QF booking us on CZ despite their partnership.
QF Call centre staff similarly suggested a SYD > HKG > DOH > CAN because of the Oneworld restriction, but never called back after saying they would investigate it offline.
QF ground staff said they could speak to FF to potentially convert QF SYD > HKG J tickets at 7am, after I suggested I could make my own way from HKG to CAN.
I know this might break other rules/affect my return Award flight on the same PNR.
CX ground staff, after about an hour, but much less push from my side, were more helpful.
They had a direct line with head office and were prepared to move us to a SYD > HKG flight right before the first HKG > CAN flight operating after the typhoon.
That flight was converted into cargo only (crew issues?), after which they put us on the next direct flight from SYD > CAN, departing in 3 hours' time.
This meant we arrived in CAN earlier than expected which was an incredible outcome to say the least.
SZX and HKG were closed for 24 hours, while CAN, ~100km away was operating normally.
I'm not sure if I got lucky here because CX was willing to escalate? Or because there is a contractual reason to rebook me.
Worth noting that around the time I went to the airport, the system automatically offered me J seats but departing 3.5 days later. I didn't accept the change and was talking to CX ground staff by then.
Again, a huge thanks to this community.
