The couple was lying on three seats of the aeroplane. A passenger was horrified after seeing two travellers cuddling each other for an entire aeroplane ride, as detailed in an X post with 21 million views.

“Can’t believe my view on the plane. It was like this the whole four-hour flight,” said one of the users on social media platform X. It got more than 21 million views.

More photos on the post show the unidentified flyers locked in a series of embraces while lying across a row of seats as if in a love motel at 30,000 feet.

One of them even had one of their feet propped against the tray table.

Needless to say, many X users didn’t appreciate the passengers’ actions. “This why I’m never flying economy,” said one user. One revolted viewer added: “How did the flight attendant not say anything???”

Experts have expressed concerns over such practices.

“Once you get to the point where you’re tonguing your partner down, you’ve crossed the line of good manners,” US etiquette expert Elaine Swann told travel blog The Points Guy.
