Cathay Pacific Asia Miles - CX fare class codes

Hello:
I am trying to find a list of fare classes for Cathay Pacific, and have searched Flyertalk and Google, but no help. Any idea where I can find?
Specifically, I need to know which fare bucket an award ticket using AA miles comes from, in either Business or First.

Many thanks,

F award inventory: Z
J award inventory: U

Thanks a lot - all the info I needed on that thread.
