I've been to this airport many moons ago for a layover and I don't remember it being this nice and organized. The signage for gates and restrooms are very visible and well lit. So many windows to see the outside but most of all to allow the sin to brighten this already bright airport to shine even more. The natural light is awesome!
Now this airport is huge in terms of space. Terminals are spread out so getting form one terminal to another to catch your connecting flight can be a workout. I recommend you have a FITBIT or Garmin to keep track of your steps. Good thing about this place is that it has the people movers that get your through at a more speedier pace. Just as a courtesy to others stay to your right to allow those in a rush to pass.
Lots of shops and eateries here at Sky Harbor. Didn't get to try any of them but from what I saw they were packed with customers. Hey early morning shot of Patron is a good way to wake up or not!
I would like to come back and just stroll through the terminal and see what else they have, but until then a hui hou!
