I have a question about terminals. I noticed that most newer terminals are linear creating very long walks from the security checkpoint to the gates. In addition, the whole terminal in effect becomes a corridor with narrow seating areas to the sides. Older terminals at JFK and LAX in particular are high ceilinged, circular spaces which means that you can see all the gates at once, sit anywhere in the terminal and no walking down endless corridors. Why is the new paradigm long corridors?
