I flew down to PDX and back yesterday. There was one elderly oriental gentleman on our plane who was actually supposed to be on the plane to Vancouver. Unfortunately he didn't speak English and wasn't reading the hand signals to follow the crew off the plane. There were eventually at least half a dozen crew members on board, ground and flight, trying to convince him to leave our plane and board the right plane. You could tell that they were somehwat more tense than they usually would have been.
Other than that, the airport garage, the airport and the planes were strangely empty. It makes me sad that people are so afraid of dying that they can't continue living.
