The customer satisfaction index distributed quarterly by the University of Michigan is out again. This quarter, the survey ranked airlines, cell phone companies, cable and others. The results are amusing. Would you believe that the typical American airline got a lower score than the IRS? We really dislike the airlines. As you might have guessed, Southwest ranked the highest in the airline survey while United ranked lowest. In fact, United received the second lowest score of any airline in the 14-year history of the survey. Only Northwest Airlines got a lower score in 1999. In chain restaurants, Olive Garden got the top rating. The top-rated hotel was Marriott, followed by Hyatt and Hilton. As for cable and television, DirecTV and Dish got the highest scores. Charter Communications and Comcast ranked lowest. In the cell phone industry, Sprint got the worst score. Verizon and T-Mobile were tops. As for package delivery, FedEx got the best score. UPS and the USPS got fairly high rankings, as well. But FedEx has been on top for 10 years.
