I'm a OneWorld Emerald (through being British Airways Gold) and I have been since January. However, for some reason the AA system sees me as a Sapphire. This doesn't happen on any other OW airlines who all recognise me as Emerald.

I fly back and forth to the US and domestically frequently so this is really starting to irritate me. To most airport staff the BA card means nothing if the computer is saying something else. The major issue is lounge access, of course.

Does anyone has any ideas how I could get this fixed?

Customer services on the phone seems pretty unhelpful, airport staff get the issue but have no idea how to fix it. It doesn't seem like this is going to happen automatically given that I've been waiting nearly 4 months now so some manual intervention is looking like the best option.
