It is no secret that airline passengers can be a bit messy. Potato chip bags stuffed into seat back pockets, blankets everywhere, lavatories a mess, and galleys stuffed with trash. By the time the next round of passengers steps on board, however, the aircraft is sparkling clean and ready for the next flight, but how does that happen? In the short 10 minute span between the time passengers are offloaded and the next flight begins boarding, a team of cleaners are brought on board, and do what most passengers will never see.
