Flight attendant shares the unspoken rules most plane passengers don’t know to follow: ‘This is a double no-no’

Flying high isn’t all peanuts and turbulence — at least not if you’re Argentine flight attendant Barbara “Barbie Bac” Bacilieri.

The 29-year-old YouTube star, who entertains 2.7 million fans with her in-flight tales, just spilled the no-fly rules she thinks all plane passengers should follow.

Rule No. 1? Keep the wisecracks to yourself — the crew’s got enough on their hands without your stand-up routine at 30,000 feet.

“When the ‘Society of the Snow’ movie came out, a passenger told me, ‘If anything happens, I give you my consent to eat me.’ I was like ‘What?!’” Bacilieri told What’s The Jam.

She added that others even have the nerve to joke, “Who’s flying? If it’s a woman, let me know, I’m getting off.”

All jokes aside, Bacilieri says there are other practical rules, especially regarding things like food and drink for flyers to follow: no plane tap water and no yogurt left out “on ice bags” for hours.

For comfort and safety while flying, she said to leave the stilettos in the suitcase: “I never wear heels… in an evacuation, you would have to take them off so you don’t damage the slide, and at the airport you have to walk a lot.”

And be cautious when entering a plane bathroom: “Do you think the liquid on the bathroom floor is water? You can’t imagine everything that’s in there.”

“Besides, the airplane carpet isn’t very clean either,” she told the outlet.

Boarding early? Forget it. “Some passengers start queuing at the gate before the plane has even arrived…Why queue to board if you’re going to have to stand around waiting for so long? I prefer to wait until the end for everyone to get on and then I go quietly.”

Sadly, the blankets aren’t sacred either, she says: “Even though the blankets are washed before each flight, they’ve been used by so many passengers that you never know what might be in there.”

When it comes to air travel, Bacilieri’s mantra is clear: humor sparingly, pack smart and trust your instincts — the sky isn’t always as clean as it seems.

Regarding other flyer rules, especially when it comes to fashion choices — as previously reported by The Post, another veteran flight attendant says rompers, sandals and skimpy tops are a first-class ticket to pee-soaked floors, filthy carpets and frostbite at 30,000 feet.

“This is a double No-No,” Dallas-based flight attendant Cher declared in a viral TikTok earlier this spring, slamming the trendy one-piece. “I would never, never, never wear a romper.”

In other words, the next time you fly — leave the heels, the jokes and the rompers at home, and maybe you’ll actually land in one piece.
