Isn't that because the two mileage programs are not merged yet? You want to use US miles to upgrade on AA metal?
AA does have some very limited mileage upgrades for partners, but it generally involves full-fare economy to start with. We don't see too much discussion about them here. I can't use them because of the fares required. In the case of BA, you would only upgrade to premium economy.
