I called yesterday to ask about LAX-LHR in J around New Year's. The agent was very sharp, understood I wanted a BA codeshare on AA metal. Priced out at $3427 each RT, which is about $250 less than on BA or AA. She also offered an Air New Zealand flight at $2836 each, but I'm a OneWorld guy, not Star Alliance, so I turned it down. She also explained the difference between the old 2-for-1 program and the current one, the 5X points bonus, the Pay with Points option, fare class restrictions, etc. I was impressed.
