A passenger’s unusual behavior during a flight has ignited a storm of criticism on social media.

TikTok personality Ozan Cetinkaya, who divides his time between Izmir, Turkey, and Quebec City, Canada, found himself at the center of an online debate after a recent in-flight coffee-making episode.

Rather than requesting a cup of coffee from the flight crew, Cetinkaya took matters into his own hands, literally, by preparing his own brew right at his seat, complete with grinding fresh coffee beans.

He shared a video of himself participating in the lengthy process in his confined airport seat, and it did not go over well with viewers.

The video of his in-flight barista skills quickly went viral, amassing over 1.7 million views, and sparking a flurry of criticism directed at Cetinkaya.

The footage shows Cetinkaya opening a sealed bag of coffee beans, pouring them into a grinder, and then persistently cranking the grinder by hand.

He proceeded to use another gadget to press the ground coffee before transferring it into a portable espresso maker.

The video ended with him pouring the finished coffee into a cup.

‘POV: Making espresso at 35,000 feet,’ he wrote in a text overlay.

People were quick to share their thoughts in the comment section, and many bashed him for being disruptive to his seat neighbors and branded his behavior as ‘unbearable’ and ‘obnoxious.’

‘Being insufferable at 35,000 feet,’ one person snarked.

‘Coffee lovers are unbearable,’ scathed another.

‘My seat neighbor nightmare,’ announced someone else.

‘How to be the most obnoxious person on a plane 101,’ read a fourth comment. 

‘Seriously bro. Your coffee can wait,’ said a fifth.

‘You can live without espresso until you land,’ wrote a different user.

It comes months after an influencer was slammed after she filmed herself assembling a meal midway through a flight – which included ‘stinky’ boiled eggs. 

To get her through the 10-hour journey from Los Angeles to Paris, Jess Marra came prepared with several containers filled with various ingredients so she could create a healthy dinner for herself to enjoy while flying.

After the 33-year-old shared footage of herself prepping the meal on the plane in June, she was stunned to see the clip go viral on Instagram, garnering 1.5 million views and thousands of comments filled with backlash.

‘What started as a fun travel moment turned into the international egg scandal of the year,’ Jess, who works in digital marketing, told What’s The Jam at the time.

The video showed her unpacking the various ingredients and assembling a salad – but viewers criticized her for doing so on a busy flight and for including boiled eggs, which can have a pretty poignant smell.

One person commented: ‘New fear unlocked: I get on a plane and the person next to me starts making an egg salad.’

‘Just because you can eat an egg on a flight doesn’t mean you should,’ another user agreed.

Someone else added: ‘Between the egg, the elbow jabbing into your neighbor, the salad shaking and the “influencing” I am 100 percent annoyed and I’m not on the plane. Just be a normal person and stop trying to gain attention.’

‘No one likes you on this flight… no one,’ wrote one viewer.

Another user added: ‘Sorry honey, but no. Eggs – no. Multiple Tupperware containers no. 

‘Assembling a salad on the plane no. It’s not your kitchen, it’s a tiny shared public space in which we all just try to survive.’

Despite the backlash, Jess insisted that her meal didn’t smell, saying she doesn’t overcook the boiled eggs deliberately to avoid any odor.
