I have lost my AA status but have quite a few 500mile upgrades. I travel frequently with someone who is AA gold and one time since we were on the same PNR, the gate agent was able to use them. Now I'm not sure if this was the exception or the norm but my question is as follows:
Can a non status AA flyer (British airways silver if that matters) fly with an AA gold on the same PNR and use their 500mile upgrades on the party? Would this work on flights to Mexico?
