Airhitch is a user-run system for hitchhiking on commercial airliners. It was starte by a group of U.S. college students in the 1960s. People who travel in this way generally refer to themselves as Airhitchers. Most airhitchers fly between the United States and Western Europe. Before Airhitch migrated to internet based communication in the 1990s, it operated out of North American offices including New York, Los Angeles(Santa Monica), San Francisco, Seattle, Montreal, and Vancouver, and numerous European cities including Paris, Amsterdam, Berlin, Bonn, and Rome. Airhitch is a non-commercial system/method/process. Today virtually all exchange of Airhitch information takes place in an AIM chat room. In the chat room Airhitchers use their real names, while the staff use screen names such as Airhitch01, and Airhitch08.
