One of the small joys of flying on a long-haul flight is kicking off your shoes as the air pressure makes your feet, ankles and legs begin to swell.
But according to a flight attendant, who shared her travel tip in a Reddit forum thread, passengers should never, under any circumstance, take off their shoes on a plane.
And while there is always going to be a bit of curiosity about what goes on behind the scenes on a flight, sometimes the details are a bit too much to handle.
So, if you’re queasy, it might be best to look away now, otherwise welcome to the very often gross world of flying.
Seeyou_never took to the forum, saying: "I’m a flight attendant… So many incidents occur on the plane that everyday passengers don’t see or consider."
"My last flight an elderly man accidentally s*** on the floor stepped in it and walked on it like it was nothing.
"DO NOT WALK AROUND BAREFOOT. Pee and Poop happen, all over."
So, the next time you’re on a plane and thinking about taking your shoes off, perhaps reconsider that decision and pack a pair of in-flight slippers instead.
