"Airplane travel is nature's way of making you look like your passport photo"

This quote by Al Gore is an amusing method of pointing out the reality of flight. It implies that the long hours of sitting in a confined airplane seat can take a toll on one's look. After a long flight, it is not uncommon to look disheveled and tired, which can make one look similar to their passport photo. This quote is an easy going method of acknowledging the physical and psychological stress of flight. It also acts as a tip that, no matter how unpleasant the journey may be, it is still a privilege to be able to travel by air. In the end, the quote is a funny method of advising us to value the chances that air travel offers.
