AUS/LAS/SEA/SAN/BNA/BWI/BOS/PHX all have (or will soon have, in BNA's case) LHR service on BA. DCA obviously can't. If AA isn't just picking up an existing BA route, but actually providing service from a city with zero LHR service, that leaves MCO (which has LGW service), CLE, IND, CVG, CMH, PIT, ORF.
All of which would be very strange routes to LHR on AA metal, though maybe a 787 could do IND/CMH/PIT?
