I've taken SuperShuttle to and from the Pittsburgh Airport for years. They are prompt: my wait at the airport has always been reasonable for a shared ride service and my pickup at home has always been within the stated 15-minute window - usually early. The drivers are usually very courteous and friendly, and the route they take is time-efficient. Only once in over 50 trips did I get a driver who seemed to get lost, and he was also the only one who talked too much; all others seemed very sensitive to whether I wanted to chat. Last year I had a van that was a little run-down and I told them that on the satisfaction survey; this year the vans I've had are in excellent condition, potentially new. I will continue to take SuperShuttle with every trip to Pittsburgh.
