I am still asking CX to give me Y miles from a FULL-FARE Y ticket upgraded to J using miles. After the mileage upgrade the code is U, and apparently the new system doesn't give miles with U-code, although in my case it's not a redemption booking but upgrade (I paid full fare, not even discount fare), another CX systemic problem.
