Everyone knows that traveling can wreak havoc on your immune system. Between the recirculated air on-board the plane and having to take your shoes off during security, the whole flying experience is a germaphobe's worst nightmare. According to a Reddit thread of flight attendant's spilling their secrets, apparently tray tables on airplanes are absolutely teeming with bacteria!
The flight attendants revealed that the trays are "rarely if ever sanitized" as some passengers use those trays to change their baby's diapers on the surface.
To make matters worse, the thread also includes data from an experiment conducted by Travel Math. A microbiologist collected 26 samples from five airports and four flights in an attempt to determine the dirtiest places on airplanes and at airports. The study deemed that airplane tray tables are dirtier than airplane bathrooms!
Needless to say, I'll be bringing my own wet wipes on flights from now on.
