Still close to impossible dream because AS does not see the same CX availability as the oneworld members even with so many daily flights between US gateways and HKG. With Thrice weekly flights on a seasonal route that is newly created? one can continue to dream.

On top of that CX seems to have tightened up A Lot on its generous policy in the past when releasing premium cabin award seats.

Using AA miles to CPT the most practical way is to redeem on QR going thru DOH. If one gets lucky one might get the A350 route which has the Qsuite, beats CX fatigue J seat by much more than a mile. lol.
