Today I flew out of Terminal 2 and have now successfully flown into and out of each of the three terminals, so I now feel comfortable giving Sky Harbor some words.
Positives:
-The name Sky Harbor is certainly the coolest airport name in the country. No dodgy old white man lays claim to the appellation of Phoenix's gate to the skies
-Free WiFi (this is such a necessity for a good airport nowadays)
-Never actually crowded (security is usually a breeze)
-Connection to the Lightrail (though in 2013 there will be a direct connect instead of a bus)
-North and South curbs make picking people up a breeze, especially when you understand how the airport allows equal access from East or West Valley
Negatives:
-The whole ground transportation system is poorly labeled (especially when compared to the paragon of this: Oakland)
-Baggage takes forever to make it from the plane to you
-North and South curbs make no sense to a visitor
That being said, for the 5th largest city in the country, Phoenix has one of the easiest airports to get in and out of.
