Will be taking a CX flight from HKG-LAX in economy class in Sept but on an AA ticket (as I'm flying with AA onto Orlando and AA ticketing was cheaper). This is my first flight in economy for almost 2 yrs and first using AA ticketing.

question:

On the CX flight to LAX, would CX treat me as a diamond member (i.e. in terms of priority for op-upgrade etc) or would the fact that I'm boarding using an AA ticket make a difference?
