This book is not just about air travel. It is about the emergent social world of flying. It concerns air space and behavior in the air the way someone else might look at cities and street behavior. Economic, political, and cultural aspects are all considered. . . . Airports have now become specific places in their own right that, in a certain sense, now. . . are very much like cities. Frequent flying also has produced its very own culture. Rules of behavior are subscribed to in the air. Unique behaviors at terminals and in the passenger cabin have emerged that contrast with life on the ground. In chapters below I explore these interesting aspects of etiquette, eroticism, and bi-coastalism, a human activity that is only possible because of our present society's evolution. . . . Only now have we begun to appreciate our emergent global culture. The world is shrinking just as the opportunities for travel expand.
