Anybody have any idea why BA hasn't gotten AA to make their ATL-BNA flights codeshared? If you are in Nashville and want to fly to LGW on oneworld carriers, then going through Atlanta would be your shortest routing. As it stands, the only routings on a single Oneworld ticket involve backtracking to one of AA's midwest hubs or traveling south to Miami. I know that the BNA-ATL is turboprop only, but it seems like it would save a lot more time. Anybody have any insight on this?
