Steve Penk's daughter Natalie, 27, said she feared for her life after a man began running up and down the aisles, shouting and spitting at staff, during a flight from Heathrow to Dubai.
After 45 minutes, the man was finally restrained and handcuffed, as he yelled: "I have a bomb and you're all going to die".
Describing the ordeal in an email written to her father - a former Virgin DJ in Britain - Natalie said: "It was absolutely dreadful. I've never felt so scared in my life.
"All hell broke loose. He was restrained on the seats but was literally howling at this point. He was screaming "you're trying to kill me, I'm going to die".
"He then started shouting "I have a bomb", with an hour of the flight still to go. I've never been so relieved to get off a flight in my life."
Natalie said the drama broke out about two hours into the flight when the man, who appeared to be drunk, had to be calmed down by cabin crew.
A few hours later, he began running up and down the aisles. Cabin crew moved him to a new seat in an attempt to calm him down, but he began hurling abuse at them, calling them racist and fat.
According to Natalie - who was travelling to Dubai for a five-day holiday with her husband Jack - his behaviour continued for around 45 minutes until he was handcuffed.
The flight landed in Dubai as normal and the incident was handed over to police. It is not known what happened to the passenger.
