Make conversation with the people sitting next to you. I have met some of the most interesting, if not entertaining, people on airplanes. Do not upset the flight attendants by pushing the call button every five minutes. They are under pressure and are responding to the needs of 300 other people. Bring a sweatshirt.
Planes tend to be very cold and the blanket supply is limited.
These are just a few things to keep in mind before the mass exodus from Detroit Metro airport to your respective homes. Last Thanksgiving, my wait at the airport was considerably long. As I meandered through the corridors, I was unusually aware of my surroundings. I began to notice things that I had never thought to look for before. I felt like an invisible observer.
