Recently used this service when I was on a hiking trip to Havasu. I needed a inexpensively but reliable way to get from Phoenix to Flagstaff. The shuttle was great, they even got me on an earlier van when my flight arrived early. Big Al the driver was very nice, he even had water for the passengers and stopped half way (3 hr trip) so we could have a bathroom break. The return trip was just as good although that driver wasn't quite as charismatic. I would definitely use the service again!
