Jon Udell has an extremely interesting post about Ed Iacobucci and the reinvention of air travel, essentially moving from a hub-and-spoke routing model (which is akin to line switching of a telephone network) to a model that more resembles packet switching. Instead of holding routes constant and let the passenger’s time be a variable, this approach allows the passenger to price his or her own time, and have the airline (with smaller and more flexible jets) respond accordingly. Very interesting, especially in relation to the concept of free flight, where air planes choose their own routes (and, implicitly, manage their own security envelopes) from one destination to another.
