I think van helsing took my response as being snide. Apologies, no such intent. Said girl probably didn't know that the rules are clear - that codeshares on non-OW member/subsidiary metal are not eligible in OWEs.

RTWs and their kin are products that not many sales reps or CSRs see, so there's no deep reservoir of expertise on them in many field stations and branch offices. BA seems especially to be prone to mis-statements when shooting from the hip, although eventually the rates "desks" usually sort it out, but only after putting customers through some hassle-laden process. It's not a perfect oneWorld.
