November 5, 2018: Well, thats what they say anyway! Airports seem to now be concerned with offering cleaner bathrooms and are using electronic means to monitor cleanliness — seven airports around the country, including LAX on the west coast, are using something called “Trax” to monitor restroom customer traffic and alert maintenance when a clean up is needed — usually after 300 people have “done their business.” According to Trax, the dirtiest bathrooms in airports are those nearest departure and arrival gates. Next airport challenge may be “where to find public water fountains?”
