The younger brother of socialite Paris Hilton has agreed to plead guilty to attacking several flight attendants aboard a British Airways flight from London to Los Angeles last year.
Conrad Hilton will appear Thursday in a downtown Los Angeles federal courtroom to be arraigned on a misdemeanor assault charge, said Thom Mrozek, a spokesman of the U.S. attorney's office. Hilton is not expected to enter a plea during the hearing, he said.
He faces up to six months in jail, Mrozek said. He also faces a year of supervised release and fines.
In the signed plea document, Hilton says he is pleading guilty "because I am guilty of the charges and wish to take advantage of the promises set forth in this agreement, and not for any other reason."
As part of the plea agreement, Hilton cannot argue the facts of the case, must attend all court appearances, cannot commit any other crimes, pay all fees and "be truthful at all times."
Hilton surrendered to the FBI in February after being charged with assaulting the flight crew to the point where it interfered with their ability to perform their duties, according to a U.S. District Court federal criminal complaint.
Hilton was a passenger on Flight 269 on July 31 from London to Los Angeles and repeatedly entered the bathroom to smoke marijuana and tobacco, according to the plea agreement.
During the flight, passengers appeared frightened and children were crying as Hilton allegedly carried on a tirade.
At one point, he became belligerent and called the crew and passengers peasants, according to the complaint.
He approached a flight attendant and shouted, "You need to stop squaring up to me" and threatened to kill him, according to the complaint.
After yelling at another flight attendant, Hilton tried to punch a crew member but missed, prosecutors said.
Hilton reportedly grabbed a flight attendant's shirt and said: "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."
As Hilton misbehaved, crew members held two safety briefings to review the possibility of restraining him, authorities said.
While he was sleeping, authorities said they restrained him.
Police boarded the plane and talked to Hilton, who allegedly said he intimidated the flight crew members because he was defending himself.
