That is just crazy.After Cathay cancelled my flight and moved me to the next day, 9 hour HK transit becomes 24 hours and 10 MINUTES (yes ten minutes) stop-over. AA wants additional 30K points for that 10 minutes and they wouldn't budge (maybe they can't as Cathay is controlling the flights).
Anyway, they agreed to cancel my reservation without any penalty. In the meantime, I reserved HND-SIN-KUL-PER flight, with SIN-KUL in Economy (1 hour), the rest in Business; extra stop, not ideal but some benefits: HND instead of NRT, overnight flight in place of early morning flight, ie saving an accommodation in Tokyo, but we were looking forward to The Wing in HK.
Just got confirmation from AA, everything is OK, fingers crossed.
Surely the ticketing rules only have to apply at point of ticketing? Or re-ticketing for passenger voluntary changes.
