Paris Hilton's younger brother has appeared in court charged with threatening to kill crew members on a British Airways flight from London.
Conrad Hilton, 20, who appeared in shackles, was allegedly in a rage for much of the trip to Los Angeles.
An FBI agent said he began pacing the aisle and complaining that a passenger was giving him a “stink-eye”.
Children were left crying as he allegedly called passengers “f***ing peasants” then threatened to kill and bury cabin staff.
He allegedly told crew members: “I could get you all fired in five minutes. I know your boss. My father will pay this out. He has done it before. Dad paid $300,000 last time.”
His father is businessman Rick Hilton, grandson of the Hilton Hotels founder — also called Conrad — and father of socialite Paris, 33.
Hilton is said to have been angry over his break-up with a girlfriend. He is accused of interfering with a flight crew and could face a long prison sentence if convicted.
He did not enter a plea and was released on bail of $100,000 (£65,000) by the LA court.
