Thanks.
See, e.g.,
this thread. You should also check out the BA board's
upgrade guide and ultimate ba guide.
Regarding miles credit see
this thread and the link within.
I see you have also
cross-posted this on the BA board that is probably a better place for it. In that thread you state that this is a transatlantic BA flight, if it is from the US to LHR you cannot credit the flight to AA.
