OTHER LISTS TO WATCH

uAirline: The authoritative American Customer Satisfaction Index tracks airline customer service performance over the years and can offer a reliable indicator of the reputable, and disreputable, airlines.

uCar rental: This is a difficult industry to track. The best- known list is J. D. Power’s customer service ranking, in its 21st year. Avoiding the low- scoring companies might be a sound strategy.

uCruise: You can get a pretty good idea which ships are unsanitary by reading the Centers for Disease Control and Prevention’s Vessel Sanitation Reports before booking.
