I’m a flight attendant — we judge passengers who order this sketchy beverage

Plane passengers who demand this hot brew make the cabin crew say “eww.”

A tall order of judgment is on the menu for jet-setters thirsty for decaffeinated coffee at 30,000 feet, warned flight attendant Leanna Coy.

“I think we all know by now that ordering coffee on a plane is a little bit sketchy,” said the skyway whiz in a TikTok vid, emphasizing her disgust for the brown stuff with the green nauseated emoji.

“You’re telling me,” she continued, “you genuinely enjoy the taste of that airplane coffee so much that you’re willing to drink it — not out of the necessity for caffeine — just for the flavor itself?”

It’s just a cup of mud without the buzz.

But be it regular or decaf, coffee served while up in the clouds is “gross,” according to whistleblowing air hosts.

“The fact that the tanks rarely get cleaned that the water is in should be the least of your concerns,” explained Kevin, a flight attendant turned commercial pilot, in a trending tell-all.

“For me, it’s always been the way that flight attendants have to clean out coffeepots,” he added, revealing that the java gets dumped into an airplane toilet — bringing the pot’s spout dangerously close to the filthy bathroom bowl.

“I imagine that there’s some kind of backsplash of particles, bacteria, whatever that goes directly back into the coffeepot,” said Kevin, “which gets put right back into the coffee maker.”

First Officer Paul Janowicz, an experienced Delta Air Lines pilot, even ranked coffee as one of the top five refreshments trippers should avoid after takeoff.

“While it may be nice for those early morning flights,” the captain told Well+Good, “the caffeine in coffee will dehydrate you in an already dehydrating cabin environment.”

Rather than gulping down a cuppa beans, experts laud water as the best beverage to sip while cruising on an airship.

“Most people understand that water is the standby choice of air passengers, and many opt to bring their own water bottle on a plane,” Lisa Valente, a nutrition specialist with Healthline, told Fox News Digital, too, hailing juices and seltzers as prime picks.

“I love plain water on a plane,” she said. “It’s hydrating and always a good choice.”
