If I read the rules correctly, the change would get me about 4000 more EQM. Will definitely try again. Is there a "best number" to call for BA RTW? I had been skyping to JNB as ticket was originally issued ex CPT, but US # has been willing to make some changes and I've dealt with them successfully 2-3 times, always with transfer to another agent though.
Note that with ExpertFlyer, you can only choose London or New York as your point of sale, but the availability as seen in JNB may differ from NYC and LON. (Unlikely in this case but it certainly can happen.). Also you should try to replicate the connections you have in your search in case any married segment logic comes into effect.
I have no idea what BA are talking about. There was a rumour on the BA forum that telephone sales were told to stop booking AA codeshares, but my contact at BA sales did not know anything of it. (Unfortunately he cannot do RTW products or I suspect he'd be very popular here.) So the more likely option is that they don't know how to do it and are making up a rule.
