On every flight the flight attendants always stand at the door of the plane and politely and with a smile welcome the passengers of the plane,

This movement is of course very vague, but the greeting is not done exclusively for reasons of politeness.

Actually there is another reason why this happens and that is the so-called face control.

The real reason a flight attendant is always in this position when passengers board the plane is to “check” them in, one by one.

They see the face and observe their movements, the way they walk or move, so they can understand if someone needs help and can’t say it (eg in the case of a kidnapping) or if someone is potentially “dangerous”.

At the same time, the flight attendants see if someone is drunk entering the plane or who avoids eye contact with them.

So, they restrain this and thus pay more attention if, for example, you do some movement that is not allowed inside the plane.

They also look at what personal items you carry in your hands, if someone is very scared and has a talisman or is nervous, for example.
