Can you point to an occurrence?
Also, on what basis could AA do this? Is there something in its T&Cs that would allow it to do it (my rudimentary knowledge of contract law says this would not be allowed - a done deal is a done deal)
I would agree with pandaperth. No one has ever reported this happening. And what could be wrong with using a US based credit card in this context. If I am on the ground in JNB purchasing a xonex I can use a US based credit card, if I have a relationship with a travel agent in JNB I can use a US based credit card to purchase an xonex.
