Clip of passenger's 'mind-boggling' behavior on flight goes viral on Instagram

A passenger is being shamed online for propping their bare foot upon the armrest in the seat row in front of them during a flight.

The clip of the incident was shared on the popular Instagram account, Passenger Shaming, on Dec. 7 and has over 400,000 views.

In the video, a person's foot is seen protruding out from the seat behind and lying across the armrest of the window seat in the row in front of them. The camera then zooms back to capture the unamused look on the passenger sitting in that window seat.

The Passenger Shaming post tags Andrea Gormsen as the annoyed traveler.

"The fact passengers won’t speak up is mind boggling!" said one Instagram comment. "I’ll be damned if a person ever has there foot up on my arm rest!"

"Seriously, what grown adult does this with no remorse?" replied another.

"Why would anyone think this would be okay?" asked a commenter.

This is the second time in recent weeks that bizarre foot behavior on flights has gone viral on social media. On Jan. 1, a Twitter user posted a video of someone swiping through the Delta in-flight movie options with their bare foot, captioning the clip with: "I fly a lot and this, by far, is the most disgusting thing I’ve ever seen on a plane." A popular Reddit post in November featured a passenger's photo of the person behind her propping their feet up on the top of her seat.
