A couple traveling with Jetstar was caught on camera getting involved in a sex act during a flight. The video was captured by Australian TV presenter Darren McMullen.

McMullen posted the video on his Instagram account showing the two passengers joining the Mile High Club. The video allegedly shows the passengers in their seats as the man's female companion touched him in front of other passengers. It remains unclear where the flight was traveling to.

McMullen, who was sitting in the seat behind the passengers, first took a close-up of the woman. The former host of "The Voice Australia" captioned the video "Jetstar is the best." He then ​got a wider angle shot of the couple. The video also showed other passengers who seemed unaware of the erotic scenes unfolding nearby, the U.K.'s the Sun reported.

When the man's seat rocked back and forth, McMullen locked the camera on himself, where he appears to say: "What the f---."

He shared another video with the caption "credit where credit [is] due," and goes to congratulate the male passenger and shakes his hand. He then says: "Hey man, I’ve got to say, that was legendary. My new hero."

Later, McMullen said: "I can’t believe I just shook that guy’s hand. That hand... I just got carried away. It’s not that often you see such a blatant disregard for airline laws. Didn’t give a f---. Guy’s horny. Go on my son. Go on." He concluded: "I need a bath."

In a statement to Australia's news.com.au, Jetstar confirmed it was investigating the incident.

"We have a zero tolerance to inappropriate behavior and encourage passengers to report any incidents to our crew," a spokesperson said.

Last year, a video went viral showing a couple on a Mexico-bound plane allegedly having sex. According to the Daily Mail, a husband and wife who were traveling on the same plane saw the couple sitting two rows behind appearing to be having sex.

The video was posted on Twitter by a user named Kiley Tully writing: "My mom and dad were just trying to have a peaceful trip to Mexico and then they sent me this."

The video received millions of views and showed a woman appearing to be straddling her companion on a seat.
