Watch out here predatory ticket and towing!\nMy spouse parked at the cell phone lot at the sky tram on Easter Sunday. He walked up to the tram exit to meet me and help with my bags, in just the few minutes our truck was ticketed and going on the tow truck. Yes the sign said \""Do not leave your car unattended\"" however, there were only two other cars in the whole lot and he just went up to the tram exit not more than two minutes' walk from the parking or standing lot. Really Sky Harbor is this the intention of the sky tram? If you don't want us to use it then fine we will go back to picking up passengers at the airport. Never again will I use the sky tram.
