Free flight : inventing the future of travel / James Fallows.
The troubles of the airline system have become acute in the post-terrorist era. As the average cost of a flight has come down in the last twenty years, the airlines have survived by keeping planes full and funneling traffic through a centralized hub-and-spoke routing system. Virtually all of the technological innovation in airplanes in the last thirty years has been devoted to moving passengers more efficiently between major hubs. But what was left out of this equation was the convenience and flexibility of the average traveler. Now, because of heightened security, hours of waiting are tacked onto each trip. As James Fallows vividly explains, a technological revolution is under way that will relieve this problem.
