Attendants didn't let me board with my fragile guitar so I had to check it in. Who knows what the freezing icicles did to it. Was not happy. Had to run to catch my connection in Heathrow after riding one bus and another train? Then, the fellow next to me asked if I would switch my window seat with his girlfriend who had a middle seat. What nerve! I said no. The food was unhealthy and the seats were cramped. Could not wait to exit.
