For years airlines have cleaned planes less than you probably think. Between flights it’s usually been just a quick clean between flights, picking up the most obvious trash but not even getting everything out of seat back pockets. First flight of the day has been the cleanest – less pressure to get cleaners on and off quickly so that planes don’t sit much between flights.
When times have been tough cleaning is an area that airlines cut back. Coming out of bankruptcy Delta wasn’t deep cleaning planes more often than every 12 to 18 months. Now that times are tough airlines will have to invest more in cleaning.
