I am flying NRT/HKG on CX in a week or so. I am Y class. What would it take to upgrade to J? I have AA miles.</font>
AA miles may be used for transpacific on CX, I think. NRT-HKG can be upgraded with AsiaMiles points. If your fare basis is Y (not the booking class), then you can also pay the difference between Y and J. Pick the second last flight of the day out of NRT. It's usually an equipment with the new J!
