When you board a plane, you're generally greeted with a warm welcome from the flight attendants.
And while most of us presume that they're simply being polite, there's apparently another reason why cabin crew say hello.
Over on TikTok, flight attendant Rania (who goes by @itsmekikooooo) explained why she always greets every passenger when they board the plane.

Turns out, they're also assessing whether you're fit to fly.
Now, most of us like to enjoy a drink or two in the terminal before we board the plane. After all, the holiday starts once you're at the airport, right?
One drink can lead to two, two drinks can lead to three and so on.
We've all had that one mate who got a little bit *too* drunk in the airport, and flight attendants have to be vigilant in making sure that passengers are in a fit state to fly.

Rania said: "Your flight attendant greets you, not only out of politeness, but also to check whether you are too drunk or sick to fly."

Not only this, checking people out is also to analyse which passengers could help cabin crew in the unfortunate event of an emergency, she added in the video's description.

Social media users were quick to share their thoughts in the comment section.
One person commented, alluding to already knowing this, saying: "I had pancreatitis when I was in Corfu, I acted normal going on to the plane; otherwise, I knew they wouldn't let me on."

A second person joked: "Me with headphones walking on the plane completely ignoring the flight attendants..."
While a third said: "Ah okay this makes a lot of sense, I always get the same look going on flights."

Another flight attendant in the comment section also added: "We look for anyone who hasn’t got any mobility issues, can speak English, looks like they will be able to open a door and ideally travelling alone.
"That makes you an ABP (able-bodied person)."

In other secret flight attendant intel, one Delta Airlines employee has revealed how to 'shoot your shot' if you fancy them, and what you absolutely should not do.
According to flight attendant Tyra, who goes by the TikTok handle @wheelsupwithtyra, there's a time and a place to do it.

The Delta Air Lines employee said: "If you see a cute flight attendant and want to start a conversation: please don’t."
However, that doesn't mean you have to miss out on an opportunity for love, as she suggested another way.
Tyra had some words of wisdom for anyone looking to flirt while 40,000 feet up in the sky.
She advised flyers: "Do not hit on a flight attendant in flight... during flight, whatever, do not do that because you are making it awkward."
Instead, she said that the best way to take your shot is to simply hand them your number when you get off the plane. That way, you're leaving it up to them if they want to call you or not, and not making the situation awkward for everyone involved.
