We used Sky Harbor Parking during our recent trip to NY State. Even though we used a Groupon we would pay full price for the efficient and friendly service we received. A shuttle brings you from your vehicle to the departing terminal with very little wait. Before you are dropped off the driver directed us on how to find the shuttle back from our arrival terminal. I mention this specifically because upon arrival into Phoenix it was late and we were pretty tired--it may have been inconvenient to investigate how to pick up the shuttle. Our wait for the shuttle again was minimal. Our drivers were courteous and professional and handled our bags with great care. Our return shuttle driver, Tim, was exceedingly nice. We've recommended this business and will use them again for our next trip out of Sky Harbor.
