If you think the skies seem particularly unfriendly lately, you’re not the only one.

People aren’t just getting bumped off their flights and roped into brawls in the terminal. A video has surfaced from a Southwest Airlines flight of two passengers getting into a violent altercation within the plane itself.

Flight 2530, which originated in Dallas, was taking a stop over in Burbank, California, on its way to Oakland on Sunday. As the plane taxied to the gate, a fist fight began between two passengers who were about to deplane. It’s still unclear why the fight broke out.

In the cell phone video, a woman who was with one of the two men, and a flight attendant, try to break up the fight, but end up being pushed onto a row of seats.

According to ABC News, the fight began due to some sort of verbal disagreement, which lead to the alleged suspect, 37-year-old Chaze Cable, assaulting the other man. The alleged victim suffered minor injuries, including a “contusion to his left eye, a laceration to his nose and a chipped tooth.”

The victim also performed a citizen’s arrest on Cable before the police arrived on the scene. Cable was charged with two counts of misdemeanor battery, to which he plead not guilty, in court on Tuesday.

A representative for Southwest Airlines said in a statement, “our employees are our everyday heroes and are trained to de-escalate conflict while delivering heartfelt hospitality on nearly 4000 flights to nearly the half-million customers who fly Southwest every day.”
