Impressive! Looks like there's ample availability on both BA and AA around Xmas. On BA.com with the AARP and CARDOFFERU discounts, I'm seeing a variety of flights priced at $1,392.
I'm curious, though: is AA's new 77W J product really that much better than BA's? (and just FYI, they now fly at least one of their daily LAX-LHR nonstops on the A380) I admittedly haven't flown it yet, though I do know the seats are exceptionally wide. Well, at least if you haven't flown SQ... :-)
