Never, never, never!
Paid in advance for SuperShuttle to pick my daughter up from LAX and driver her to her destination. It took the driver 40 minutes to pick her up, as she stood on the curb at LAX alone! The driver had four passengers, my daughter was stop #2. The driver REFUSED to drive in the carpool lane. After an hour and a half, they still weren't at stop #1! My daughter's stop was 45 minutes from stop #1. The airport is 26 miles from her destination. What is the purpose of having a van full of people if you aren't going to drive in the carpool lane? I drove this same route alone and it only took me one hour! By the time she got to her destination, the entire ride was over TWO HOURS! When I called SuperShuttle, the customer service rep asked me what I wanted him to do about it. I said I want to report the problem. He told me to do it online.
