Is it correct?
P.S: I am very surprised by all those differences between different airline reward system. Guess I should be more careful next time. Sigh.. and I will need to sit in economy class in this full flight. By full, I mean there are not seats available for me to choose on CX website...
Correct....CX can't process any upgrade request because it's an AA flight number.
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.
