I will be doing a RTW in coach and will be flying NRT - HKG - SIN(stopover) - HKG on CX.

Being a new EXP with AA, I am trying to figure out what to do with those miles. I would prefer to have them on AA, but I read that AA doesnt accept M class on CX.

What do others do in this situation? I have FF accounts with BA and Qantas. Anyone have any suggestions?

Or maybe I can see if I can upgrade the flights out of M at the airport.
