That has all changed now and AA now books upgrades under the same codes as award tickets. The only difference between AAdvantage and Asiamiles is that the latter can be upgraded on any mileage earning fare bought from anywhere. Whereas on AA, the ticket must be full Y or J and ticketed through AA themselves.</font>
Thanks for the clarification.
And what is more - in a few months' time- CX upgrades using AA miles will be a thing of the past!
