Mohammed Khelya, 22, was reportedly drinking from a bottle of vodka when he became aggressive on the flight from Manchester to Cuba on Tuesday.
Cabin crew members asked him to stop drinking and he said: "What if I f***ing am?" and "I'm going to f***ing kill you and I'm going to kill everyone after."
He also began spitting at them and a blanket was used to cover his mouth after he was arrested and detained at the back of the plane.
The plane was diverted to the LF Wade International Airport in Bermuda, and the flight was greeted by police officers, who escorted Khelya off the plane.
Khelya, from Lancashire, was fined $3,000 after admitting disruptive behaviour before magistrates in Bermuda.
He was fined $2,000 for being drunk on the aircraft and another $1,000 for being abusive towards flight staff.
