Argument on the plane escalates: "One of us will die"

Melbourne (Australia) - An argument between two men escalated on a Jetstar flight from Melbourne, Australia, to Bali on Saturday. A video posted on social media shows the brawl at high altitude.

At first, the men just argue while other passengers try to calm them down.

"One of us is going to fucking die," says one of the squabblers, then it escalates.

The threatening man is attacked himself, passengers try to separate the two. Shortly afterwards, the crew join in.

Five crew members are needed to get the troublemakers under control. A representative of the Australian low-cost airline confirmed that the incident was being investigated. He spoke of a zero-tolerance policy for disruptive and offensive behavior.

"Our crew members are trained to de-escalate incidents with unruly passengers and we thank them for the way they handled this situation," it said in its statement.
