I travel a lot, or have been the last few months. I have discovered through my travels that I like airports. I’m not sure why, but they seem optimistic places, full of potential. People get on planes with a purpose, good or bad. Often, the traveler is ambivalent; you can see it in his or her face.
I am entertained by watching people at the gate, trying to discern their reason for traveling. Most are business travelers, like myself, dressed in typical corporate traveling attire: khakis, running shoes, digital watch, laptop. There are the tourists, of course. And then there are the ones clearly forced to travel by dire necessity. These people are the most interesting to watch. All of their tickets cost too much.
As a social system in time and space, the airport is, of course, qualitatively different from any local community. It is not constructed as a permanent, self-reproducing social system. It is marked by transience.
. . . [T]he airport may function, for the traveller, as a kind of catharsis: The moment one passes through immigration into the departure lounge, one is removed from the impediments of society: Once there, neither the tax collector nor the family can reach you. You are a free individual.
