As airlines rely more on hubs and connecting flights, I think airports need to be focused around getting people from terminal x to catch their next flight at terminal y, as it's often a short time period.

Wonder what he thinks about the (no defunct) Tegel Airport in Berlin? Took you 3 minutes from the plane to the Taxi, wonder if any commercial airpot in action today can beat that?

The design is awesome, but to apply that in my country seems impossible. And good if many airport can be time efficient for most people to catch their flights on-time.

What airports need is a guaranteed throughput so unnecessary waiting time is reduced.
