‘I always thought they were just very nice’: Flight attendant reveals real reason they greet you when you board the plane

It turns out that flight attendants don't just greet you as you board the aircraft just to be nice; they're actually scanning passengers for two key things.

In a video with over 3 million views, TikToker Ioana Iachim (@ioanaiachim) wears her flight attendant uniform and pretends to greet customers at the entrance of an airplane.

"Did you know your flight attendant greets you not only out of politeness but also to check whether or not you are too drunk or sick to fly," the on-screen text reads.
