While airports and airline companies force us to accept the first seven items on the list as the new facts of life, they are According to USAtoday, airports across the United States are working to jazz up their restrooms for weary travelers. As one airport authority says, restroom cleanliness is "always one of the top five drivers of customer satisfaction." So while they repeatedly ignore the other four drivers, airports are improving the quality of their facilities by cleaning more often, and even by adding restroom attendants to their staff. Looking at a chart of the major airports' cleaning schedules [3], one can see that Atlanta and Fort Lauderdale are tops in that department, with cleanings every fifteen minutes during the day. (It's also very interesting to see a count of each airport's restrooms, toilets, and urinals.)
