Internet divided over airplane etiquette after viral altercation in the first-class cabin

A video on social media has the internet divided over what's acceptable behavior in first-class. 

A woman shared a video of herself brushing her hair in business class and revealed another passenger in the background giving her dirty looks. 

'Me in business class minding my business while aunty gives me nasty stares,' she captioned the post. 

In the video, the woman is seen brushing her hair, tying it back, and getting comfortable in her spacious first-class seat. 

While she brushed her hair for the video, another woman was seen looking at her in shock and disgust. 

The original creator turned off the comments on her post, however, an Instagram account reposted the video with the caption, 'I just want to brush my hair in peace.' 

The altercation prompted a swift reaction from the internet, with many sounding off in the comments on whether it was appropriate behavior or not. 

'Miss Ma'am there's a bathroom in first class big enough for all that,' one comment read. Another agreed, 'Nah, she betta take that brush to the bathroom. (And that camera).' 

Others pointed out that it is unsanitary to brush your hair in a space where people eat, with one writing, 'I dont want someone brushing their hair next to me in a small space and are their trays down? No thank you. Keep your stray hairs to yourself.'

'It is unsanitary to brush or comb hair outside of the bathroom. Hair holds all kinds of particles and elements that become free flowing once they are released. Now you know…' another informed. 

'Yeah don't brush your hair next to me in business class. This is not your bathroom,' a fifth wrote. 

'I dont want to see anybody brushing their hair either! I dont care if its yours or not. Gross!' a sixth chimed in. 

While some commenters were critical of the woman's actions, others were quick to defend her. 

'Imagine being in someone else's business and all they are doing is combing their hair? Smh,' one commenter argued. 

'Like? Ppl brush their hair on long flights… ppl need to chill. Ppl also eat and go to the bathroom on long flights,' a second agreed. 

Some took a more diplomatic approach by addressing both sides. 'It's ok to brush your hair but preferably in the restroom. The hair that is being combed or brushed has to go somewhere so why not in the trash.' 

'Now sis… This is one of the reasons why so many of us come on airplanes and wipe everything down. All the glaring was unnecessary from that old lady but I can see why Delta 1, First Class or Business Class flyers might be a little leery,' another shared. 

Although social media users seemed to be divided over brushing hair in public, etiquette experts have taken a side. 

Diane Gottsman, an etiquette expert and owner of The Protocol School of Texas, told Dailymail.com that practicing personal hygiene in public should be avoided. 

'It’s off-putting to have someone brushing their hair next to you and the hair is flying into another person’s public space,' she said.

Elaine Swann, the founder of Swann School of Protocol and a former flight attendant told The Washington Post that passengers need to be aware of their space on a plane.  

'I think people are forgetting that they are still in a public environment,' she said. 'We're on the aircraft and it's small. It feels very much like this is our own space. It's not out and about, walking in the mall or what have you, but an airplane is still a public environment.'

According to a Nexstar survey, the top most offensive airplane faux pas was personal grooming.

Although survey respondents didn't directly cite hair brushing as problematic, they found that any sort of grooming including painting nails, clipping nails, trimming beards, or brushing teeth demonstrated a lack of social skills.
