Whom to ask for, AA or BA ?
Any chance to get it (2 pax, beginning Oct)
Using AA miles to upgrade on BA metal from premium economy, the only way it's possible is if you're on a full fare premium economy fare code (W). This isn't likely unless your fare was very expensive, typically it's cheaper to just buy discounted business compared to full fare PE.
If you're talking about just paying the fare difference to business, then call AA and ask, as this is an AA issued ticket. You can just pay the fare difference with no change fee.
