AA RTW desk is refusing to book a ONE with a couple of code share flights (both plain vanilla BA flights between LHR and MAD, operated by Iberia), saying "no code-shares AT ALL on xONEx fares". We all know this is nonsense, but after four calls today, and one supervisor, still no joy, so I will wait until tomorrow and try again; I 'm sure everything will automagically fix itself up, the moment I talk to a more experienced agent, but this try and try and try again, on something as simple as this, is frustrating.
