Good question. I don't fly CX much anymore but generate a lot of air miles through the AMEX card. My CX DM was on a holiday for the last time, and now technically am DM until my year end when I fall down the ranks to the bottom.
This means AMEX is my only link to MPC other than the odd regional flight.
So just being a plain Asia Miles member (albeit AA EXP) with a CX AMEX card (is it possible?) or maintaining green status is a question I need to think about. Especially as the only thing I can do is redeem miles at this point.
Does anyone have any thoughts?
