You have to imagine, most of an airplane is pretty nasty with germs.
However, if there's one spot you want to avoid touching...
It's tough because that’s where your food and drinks are served, but according to flight attendants the germiest thing on the plane is your tray table.
Seems they are rarely sanitized and one flight attendant revealed that she had once seen a woman change a baby’s diaper on one.
Ugh. Note to self: Bring sanitizing wipes on the plane.
