Most of the way there. Sitting in the Brittish Airways lounge at Heathrow waiting for the flight from London to Munich. Flight over was uneventful. First time on a 747 since all my previous long haul trips have been on 767 or 777. Also first time across the pond on BA instead of AA. Food and service were very good. Their business class (Club World) seats are nice - was a little strange facing backward though. Got about 4 hours of sleep, so I should be able to have a reasonably normal day and turn in early tonight for the big day tomorrow.
