Apologies if this was covered somewhere but I have this situation on Sunday and can't seem to find an answer.
Due to a pricing mismatch between AA and US, for a recent RT from DFW, I booked the outbound on AA.com and the return on the US website. Both flights are on AA metal. As an AA Platinum (no US status) I was able to request the upgrade on my outbound, but is it possible to get upgraded on my return (AA flight # booked on USair.com)?
