Passengers share 'weirdest' things seen on planes, including unusual foods, bare feet and barnyard animals

In the "r/delta" forum on Reddit, a user posted a provocative question recently.

"What's the weirdest thing to happen to you on a plane?" the person asked - garnering some 2,000 reactions to date.

The user opened up the discussion by sharing a photo of a flight passenger playing a wooden recorder while sitting in a window seat.

Other Redditors took to the comments section to share the wildest actions they'd seen while traveling 30,000 feet high in the sky.

"I got stuck in a middle seat years ago next to a young woman carrying an almost life-sized doll head with a full head of messy hair," one user wrote. "And no, she wasn't a hairdresser."

Another user said, "I don't like it when people clip their toenails. I've seen it three times. Twice [in] a row across from me and another time in my same row."

Another Redditor said there was an "old dude who kept asking me questions about my job even after I put my headphones on (multiple times) to work - couldn't take a hint and then said I was rude for not talking to him."

Another user described this: "Donald and Melania Trump impersonators [were in the] first row on a Southwest Flight. The impersonator knew that I had done a double take when I passed him by. I guess most [people] do."

"Passengers have a zone of personal space on the plane that roughly corresponds to the area of their seat," said Leff.

"Within that space, there are all [types] of behavior that might come under criticism (usually in the realm of personal hygiene and grooming), but it really comes down to the discretion of the individual," he added.

Whitmore also noted that it's important to practice spatial awareness. 

"The seats may be getting smaller by the day, but that doesn't give you the right to spill over into someone else's space or put your head on another person's shoulder - unless, of course, you know that person well."

As for passengers who opt to remove their shoes, Whitmore suggested putting on a pair of socks.

"From an etiquette standpoint, it is rude to walk about barefooted in a public place as many germs can be transmitted from your feet," Whitmore told Fox News Digital.

Leff noted that flying has become more affordable and democratized. 

"What that means is that all sorts of different people with different customs and expectations are now thrown together inside a metal tube," he said. 

"Humans are strange creatures, indeed," he added.
