What not to drink on a plane, according to TikToker: "It's disgusting"

Plane enthusiasts should look for the video from TikToker Kevin. He explains why passengers should refrain from drinking coffee while onboard. His view is backed by the testimony of a stewardess who questions the quality of onboard water.

In an interview with the Daily Mirror, stewardess Celina Bedding advised passengers, both frequent flyers and first-timers, to never consume tap water from the toilet.

"Studies have shown that drinking it is unsanitary," Bedding told the Daily Mirror. She mentioned onboard signs warning passengers not to drink tap water. Some passengers may argue that this is a ploy to sell more bottled beverages. However, Bedding insists these warnings are in the interest of health. "Do not, in any case, drink tap water on the airplane," the stewardess added.

Scientists also support her stance, warning that the water quality onboard planes is subpar. As such, they strongly encourage passengers to drink from sealed bottles. Besides tap water, there are other beverages to avoid while flying, including tea and coffee.

The TikToker, under the alias keVin, added his perspective. He declared that drinking coffee on a plane is simply "gross". This viewpoint emanated from comments posted on Reddit. They described how the water tanks used for making coffee are cleaned by pouring the water into the onboard toilets—a method keVin found extremely unhygienic.

"I imagine that there is a certain amount of spray from particles, bacteria, or anything else directed back into the coffee jug. This jug is then placed back into the coffee machine," the TikToker explained in his video.

keVin doesn't stop at the drink issue. The TikToker also cautions against looking into the pockets on the backseats, where he found discarded tissues, diapers, and clumps of hair.

Online communities have continued the discussion. Social media users pointed out that the ice for onboard drinks could also be derived from unsanitary water sources.
