It's often said that the quality of your flight depends on who you're sharing it with. Even a first-class ticket can be marred by a couple engaged in a heated argument or an obnoxious drunk demanding more whisky. But worse is having to share a cabin with someone with low standards of hygiene ... and no sense of personal space.

If you want an example of this kind of phenomenon, then look no further than the following video, which has gone viral on social media this week.

The video in question was shared on Tuesday by the Instagram account @PassengerShaming, along with the caption: “So is hobbling still a thing?"

The four-second-long footage was filmed on a commercial flight and shows an unknown passenger’s foot comfortably laid up on an armrest belonging to a young female passenger sitting at a window seat. The camera pans over to her face, showing her to be distinctly unimpressed by the behavior and manners of her fellow-passenger.

A number of Instagram users took to the comments to express their disgust. For instance, one person wrote: "That drink would be going over that foot," while another added: "Her face says it all."

This isn't the first time that we've covered a story about flight etiquette either. Back in November, we penned this article all about the experiences of a Reddit user, who had the passenger behind her rest their bare feet on her headrest.

In the pic, Redditor u/WoodySporano can be seen staring into the camera, with an expression of disgust and annoyance in her eyes, while another person's feet rest over her head. The snap, which quickly managed to go viral on social media, was captioned: "Going to be a long flight."
