I was just talking about this with my boss - a frequent flyer moaning session.
What was interesting to me was that however you articulate your "rating system" there seemed to be a general consensus of "good" and "bad". My home airports (JFK, LGA and EWR) fare badly (and deservedly so). Nobody likes CDG (in my group). Everybody likes AMS - those with experience of ARN mostly like it. But we do mostly US Canada and Europe. So I have the feeling the if the airport gods try to make it a decent place to wait and have nice ambiance, they are paying attention in sensible ways to things that matter also and that tends to mean that if ones aspect of your rating scale is high, the others will be also. If they think it is ok to herd 3 plane loads of pax into a hallway in the basement for an hour because the lines at immigration were too long to have us fit in the immigration hall (welcome to JFK people) then they aren't going to have much in the way of cool decor.
