Heads will roll at BAA, don't sweat about that. The Mayor of London called them to ask what they are doing.
Interestingly Gatwick, which was run by BAA until a few years ago (BAA was forced to break up Monopoly, sold Gatwick) is looking like nearly full ops Monday. And what a coincidence Gatwick has generally improved immensely since the forced BAA sale.

Go figure. BAA are a disgrace and have been for years. I was due to fly on one of the two BA flights leaving JFK tonight but my connection on Monday is canceled and no availability from LHR until Wednesday. Rather stuck in an apartment in NYC for 2 extra days (hopefully) than risking being caught in the mayhem in London.
