Los Angeles ( CNN ) Conrad Hilton , the younger brother of celebrity heiress Paris Hilton , allegedly threatened and intimidated flight attendants on a British Airways flight from London to Los Angeles last summer , using profanity , smoking in a bathroom and calling passengers `` peasants , '' federal authorities said this week . Hilton , 20 , surrendered himself to the FBI on Tuesday -- charged with interfering with flight crew members -- and appeared in court later that day , said spokesman Thom Mrozek of the U.S. Attorney 's Office . Hilton was freed on $ 100,000 bond and is scheduled to be arraigned on March 5 . The federal charge alleges that Hilton `` knowingly assaulted and intimidated flight attendants of the aircraft and , in doing so , interfered with the performance of the duties of the flight attendants and lessened the ability of the flight attendants to perform their duties . '' Hilton and his attorney could n't be immediately reached for comment . If convicted , Hilton could face up to 20 years in prison , authorities said . On the July 31 , 2014 , flight , a flight attendant told the FBI that Hilton appeared to be `` under the influence of drugs because of his erratic behavior while walking through the cabin , '' court papers said . Hilton left his seat five minutes after takeoff , even though the `` fasten seat belt '' sign was still on , authorities said . Another flight attendant said Hilton rose from his seat at least 20 times during the 10½-hour flight , court documents said . Read the federal complaint ( Warning : profane language ) When Hilton became enraged because a flight attendant was following him , he shouted several times that `` I am going to f -- -- -- kill you ! '' and used other vulgarities , court papers said . Passengers became frightened and disturbed , authorities said . Hilton yelled several times , saying `` I will f -- -- -- own anyone on this flight ; they are f -- -- -- peasants . '' Hilton also accused the flight attendants of `` taking the peasants ' side '' and then said he was angry because he had just broken up with a girlfriend , court papers said . He bragged that he was already banned by other airlines . `` Hilton frequently lamented that he wanted to smoke marijuana on the plane , '' according to an affidavit by FBI agent David Gates . Hilton also allegedly punched the bulkhead next to an attendant 's head , missing his face by about 4 inches , court papers said . He also allegedly told a flight attendant that `` 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 , '' Hilton allegedly told a flight attendant , according to court papers . Hilton 's father is Rick Hilton -- who is a grandson of the Hilton Hotel empire 's founder , Conrad Nicholson Hilton -- and is a partner in a real estate development firm in Beverly Hills , California . Rick Hilton and his wife of more than 30 years , Kathy , are parents of four children , Paris , Nicky , Barron and Conrad , making them the great-grandchildren of the hotel empire , according to Rick Hilton 's webpage . At some point during the flight , the attendant saw Hilton go into a bathroom and smelled cigarette smoke coming from it , authorities said . The flight 's pilot , who was second-in-command to the captain , `` noticed the smoke detector above the bathroom ceiling had been stuffed with paper towels , apparently to prevent the smoke alarm from sounding , '' court papers said . The pilot later confronted Hilton , and Hilton surrendered a used pack of cigarettes and a lighter , authorities said . Hilton returned to his seat and fell asleep . The captain authorized crew members to form a `` restraint team '' to restrain Hilton before he woke up , authorities said in court papers . The crew used a blanket and handcuffs on Hilton about 75 minutes before the plane landed , authorities said . He awoke while being restrained and began screaming obscenities , court documents said . `` As Hilton was being restrained , he told the flight attendants he was a model and that they were 'going to ruin my career , ' `` the affidavit said . Later , in an interview with the FBI the same day , Hilton said he started his travels in Mykonos , Greece , had a connection in Athens , and then traveled to London , authorities said . He took a sleeping pill before boarding the flight to Los Angeles , court papers said . Hilton admitted to calling people `` peasants '' on the flight , but he `` denied having a confrontation with a flight attendant near the start of the flight but acknowledged having other issues with flight attendants , '' the affidavit said . Hilton allegedly told the FBI agent : `` I told all of them I could get all of their jobs taken away in less than thirty seconds , '' the affidavit said . When Gates , the FBI agent , read federal law to Hilton , he interrupted him and stated : `` I did intimidate . But , through defense . He came up to me with his nose , '' referring to a crew member , the affidavit said . CNN 's Stella Chan contributed to this report .
