Not saying this because I live in Arizona, but because it is an excellent airport! The staff at security and throughout the airport are always happy and helpful. I like how they have attentive staff waiting to direct people near every security checkpoint. The airport itself is extremely clean (and kept up to date). They make it very easy for passengers with disabilities to get to the planes/gates. I've seen it grow in size tremendously. Terminal 4 is the largest, be prepared to hit some traffic on busy days. Overall though, they manage the flow of traffic well considering the volume of vehicles coming/going every day.
