AA GSA in HKG recently refused to issue a carefully set up xCIRC29SA (by the AA RTW desk) with payment by an Oz billed AX card. I tried several times and each time they said they would be happy to issue the ticket but at the Oz price - because the CC is billed in Oz $. They said if I could quote a HKG billed card then they would issue the ticket at the HKG price.
I also asked if I could go to their office in person with the same Oz AX cc to pay for the ticket - and they said "no".
This is very disturbing to hear. Was this before or after AA started flying to HKG? Because I wonder if the HKG airport counter or AC would issue it.
