Cathay Boy, did you ask her what CX staff think of other FFP members, ie AAdvantage?
Once upon a time ago, I knew someone from HKG CX ticketing counter at airport and they told me some interesting tales about what they really think of some of their partners' FFP members, and what chances they have at op-ups.
Lets just say that after that, I never mentioned that I'm a member with AAdvantage ever again whenever I flew!
