I'm more for the smaller airports. Like in northern Washington, ORS, or Orcas Island airport, is the most beautiful airport I have been to. With a south flow, it is like SXM
, you come in right over the Puget Sound. North flow you fly right between two hills and fly right over an active road. It is awesome.
For big airports, it would have to be DTW
. They have really put a lot of effort into making it a beautiful and efficient airport.
