TV host catches two Jetstar passengers in the act of joining the mile high club

On the long list of things you'd rather not happen on a plane, feeling the seat in front of you rock as two of your fellow seatmates get it on is pretty bloody high up there.

Over the weekend, Australian TV host Darren McMullen claims to have witnessed a woman giving her male friend, uhh, "hand relief" during a Jetstar flight.

The entire thing was documented on his Instagram story.  

The duo appeared unfazed by fellow passengers, cabin crew, or the fact they were cruising at 30,000 feet, according to McMullen. They didn't even think to head to the bathroom.

Instead, the unnamed female passenger is believed to have went to town on her seatmate, in plain sight.

The act prompted the former host of The Voice to whip out his phone and share the experience with the world – or at least his 50,000 followers.

Despite being clearly grossed out, McMullen was weirdly proud of the events that had unfolded. "Hey man, I've got to say, that was legendary," said the TV host. "My new hero."

"I can't believe I just shook that guys hand," he continued. "That hand."

"We have zero a tolerance approach to inappropriate behaviour and encourage passengers to report any incidents to our crew," a Jetstar spokesperson told 9Honey Travel.

Next time you feel the urge to get a bit freaky in the skies, please fight it – for the sake of literally everyone else onboard.

If you'll excuse this writer, he's off to wash his eyes out with holy water.
