Traveler satisfaction with airports is generally down, and LAX is no different, scoring in the middle of the range in a J.D. Power survey that found airport satisfaction down 14 percent compared to 2007. The study, now in its eighth year, ranks big airports with 30 million or more passengers per year, medium airports with 10-30 million passengers per year and airports with fewer than 10 million passengers per year. It looks at six factors: airport accessibility; baggage claim; check-in/baggage check process; terminal facilities; security check; and food and retail services. Among medium-sized airports, San Diego International scored 678, slightly ahead of the segment average of 673. For the full story visit http://www.dailynews.com/ci_9321716
