I don't often have the opportunity to fly CX , but will purchase tickets for two flying business class IAD/HKG/SYD/ & AKL/HKG/IAD. The CX miles earned by buying these tickets will be of little value to me. I'm wondering if there is a way of earning AA miles instead. I realize there might be opportunities to book AA on the CX website, but, obviously, much more flexibility on the AA site. Any ideas wpild be appreciated. Perhaps I can book the CX flights with AA??
