I have arrived in this airport more than most, its amazing! Sky Harbor offers an incredible selection of the hottest restaurants from the valley. It is a clean, spacious place that is very streamlined for travelers. if you are ever lost, they have a staff of purple clad guides that will direct you where you need to go!
traffic to and from usually flows fast enough, plenty of very visible signs help you navigate the loop around the airport.
nobody really wants to be at an airport, but Sky Harbor is a decent enough place!
