If you redeemed CX flights with AAdvantage miles, you still can't process an upgrade as award tickets AREN'T UPGRADABLE. The only time you'll get upgraded on an award ticket is if the flight is oversold and it's still VERY RARE.
Do you have elite status with AA? If you're Sapphire, I think you should be able to pick your seats on the CX website.
I see. I am able to pick my seat, but because the flight is full (like totally full) there is no seat for me to pick. But thank you so much for your answer tho. It clears all the confusion I have.
