Has the feel of your regular neighborhood airport parking service. The lot isn't much to look at, but it always has a space for my car. The drivers are regular Joes who portage your bags and appreciate tips. They drive you from your car to the automatic sliding doors of the airport, which is even more convenient than parking at the airport as you have to walk from your parking spot to the elevators, and cheaper. There's always a deal. In fact, the attendants force you to take a deal if you forget to print a coupon. Your AAA card will always work in a pinch. The Yelp deal is good too. The buses are distinctive and easy to find as long as you don't confuse them with the airport's shuttle. Make sure to read your ticket and go to the right side of the terminal. I keep going back because Sky Harbor Airport Parking is quick and reliable.
And during the holidays, you may get lucky and board the Christmas van. It is decked out with more decorations than your average neighborhood. And the driver will tell you the story of the candy cane on the way.
