A flight attendant has revealed why cabin crew look passengers 'up and down' when they get onto a plane - and it's not because they're judging your travelling outfit.
Kat Kamalani, who posts on TikTok as @katkamalani, shared a video in which she explained that flight attendants are checking out passengers for numerous reasons and they're pretty much all to do with safety.
In the clip, she says: "Have you ever walked on a plane and saw the flight attendants standing right here greeting you? Or the flight attendants walking up and down the aisle?
"Well I'm about to tell you what we're really doing.
"So, when you're walking on the airplane and you see our happy, smiling face - we're actually looking you up and down and we are trying to find our ABPs.
"And what that is called is our able body people or person - so, these are people who are going to help us in an emergency.
"For example, military personnel, firefighters, nurses, doctors.
"So, in case of an emergency, like a medical emergency or we are going to land the plane or there's a security breach, we know who is on our plane and who can help us.
"But, we're also looking for one more thing - beside from looking for things that don't belong on the plane, like a boxful of liquids - we're looking for human trafficking.
"It happens a lot in the industry and our passengers' safety is our number one priority."
So there you go - they're only looking out for you, not quietly taking apart your sartorial choices.
Earlier this year, a fellow flight attendant shared the rather grim explanation of what happens if someone dies onboard a flight.
TikTok user Sheena Marie posted a clip in which she explained that, in case of a death there's very little they can actually do.
She said: "If they have a heart attack and die, and there is nothing we can do about it, and we can't start CPR, we are just going to wait until we get to our final destination.
"We are going to keep that dead body where it is at."
She went on to say that the body could be moved, in the event of extra space being available somewhere else, such as a full row of seats being free.
The body would then be covered with blankets and medical workers would enter the plane on arrival at its destination only after customers had exited.
