Psychiatrist - I've paid the US$120 (actually charged as HK$936 in practice) before - switching CX SYD-HKG to QF SYD-BNE-HKG, and an earlier one changing MH HKG-KUL-SYD to CX HKG-SYD
The Manila agent I spoke too did not share any of the reservations of her Tsuen Wan colleague. However she got stuck in the disappearing-reappearing QR availability I described in #18 above. QR/MPO isn't going to let me get that QR815 without a fight. Or more like an Occupation.
