David Morris, 45, drank five double whiskies on the flight and unleashed a drink-fuelled tirade against cabin crew and even headbutted one flight attendant after they refused to serve him more alcohol, Get Surrey reports.
Prosecutor Izolda Switala-Gribbin said: "On a flight from Kuala Lumpur, Mr Morris was in first class travelling to London.
"Mr Morris had consumed a large quantity of alcohol. He bought approximately five double whiskies during the flight.
"He became disruptive towards fellow passengers and began pacing up and down the aircraft and demanding more drinks.
"At some point he was told he would not be served any more alcohol and that is when he started swearing and his behaviour became a lot more disruptive.
"He was offered some water by a member of the cabin crew. While drinking the water he pulled back the glass and let go of the glass and tried to punch it. He missed it but nearly hit a member of staff in the process."
Staff tried to restrain him but Morris became violent, reports the Guardian.
"Mr [Johari] Nordin was asked to assist in the restraining of the defendant and as he was trying to place plastic handcuffs on the defendant, he headbutted him. He was shocked and sustained swelling to his upper lips.
"When Mr Morris was eventually restrained he kept falling asleep and waking up, and each time he woke up he would scream", Switala-Gribbin told the court.
Morris pleaded guilty to assault by beating and being drunk on the Heathrow-bound flight on December 3.
Lance Whiteford, defending, said Morris was "horrified" at his behaviour.
He said: "I will say that appearing before you is a gentleman who is absolutely horrified at how he behaved on that occasion.
"He knows that staff, when carrying out their duties, should feel safe and do it without being abused or threatened.
"He has no recollection of this flight. He accepts he behaved the way alleged and he is absolutely horrified."
Morris is now due to be sentenced at Isleworth Crown Court on January 16.
Man admits drunken assault on Malaysia Airlines flight
We've heard of vomiting bugs in hotels and cruises but rarely on a plane. On a flight from Chile to Sydney in August 2013, 26 passengers became violently ill with gastroenteritis after celebrating at a festival in Brazil and picking up the bug before boarding the plane. Some of the passengers were taken to hospital once the plane landed in Sydney and the plane had to be quarantined and disinfected upon arrival. This is one flight we're really glad we weren't on as the Boeing 747-400 only had eight toilets and the group developed vomiting and diarrhoea.
When you're on a long (and pricey) trans-Atlantic flight, the one thing you don't want to happen is for the plane to run out of toilet paper. Unlucky for passengers on a United Airlines flight from London to San Francisco in June 2013, the toilets ran low on tissue after the airline forgot to restock its supply. The passengers were forced to use cocktail napkins instead of loo paper when nature called and were allegedly told to use what they had brought on board for the 10-hour flight. That's one way for an airline to find itself deep in poo!
We all hate flight delays and even a few hours can leave us peeved, but holidaymakers on a Monarch Airlines plane from Tenerife were stranded on the Canary Island for a whopping 50 hours in August 2012 when their plane suffered a fault. The crew discovered a problem with the door hatch and asked passengers to get off the plane and wait for three hours. They then spent another hour on the plane before being put up in a hotel. A replacement plane eventually flew them to Birmingham.
When a pilot accidentally locked himself in the toilet of a New York-bound flight in 2011, he ended up causing a mid-air 'terror' panic too. When a well-meaning passenger heard the pilot trying to get out of the loo, he offered to help. The pilot asked the man to go to the cockpit and inform the crew of the situation, but the co-pilot was completed spooked by the man's "thick Middle Eastern" accent and refused to let him in, calling a state of emergency. Fighter planes were alerted at the arrival airport and the co-pilot was told to "just get on the ground". When he managed to break out of the toilet the pilot assured air traffic control that there was no threat. But the FBI still waited to meet the plane when it landed and spoke to the poor passenger who just wanted to help.
If you're a non-smoker, you won't be able to think of anything worse than a smoker lighting up a cigarette next to you on a flight. Three Canadian passengers on a Sunwing flight did just that in February 2013 - even though smoking has been banned on aircrafts for more than 15 years. And what's more, they refused to put their cigarettes out and ended up diverting the flight, which was travelling from Halifax to the Dominican Republic, to Bermuda. When the plane landed, their passports were seized by police, while the other passengers continued their journey.
There are times when the pilots are up against nature and have absolutely no control over a situation, such as when lightning strikes. In January 2013, a Turkish Airlines flight carrying 114 passengers was struck by lightning. A passenger filmed the incident, which saw sparks from the plane's engine as it caught fire and the cabin lights flickering on and off. Fortunately, despite the plane catching fire mid-air, it made a safe emergency landing and no-one was injured.
One emergency landing is enough but could you handle two on one flight? That's what "terrified" passengers on a British Airways flight from Saudi Arabia to London endured in August 2013. First the plane was delayed for five hours and in the air for about 40 minutes before making an emergency landing because of a problem with the plane's wing flaps. Then the next day when the passengers boarded the same plane, the problem reoccurred and the flight was aborted a second time. Passengers were reportedly "physically sick and crying" during the landings as the plane had to circle the desert to dump around 20 tonnes of fuel to be the correct weight to land safely.
If the sound of babies crying on a flight is disruptive enough to your journey, you certainly wouldn't have enjoyed the American Airlines flight from Los Angeles to New York, which saw an "unruly" passenger repeatedly sing Whitney Houston's I Will Always Love You. We've watched the video and the woman is no Whitney Houston! She ended up being handcuffed and removed from the flight - but not before putting the other passengers off Whitney's music for life!
Thought a naughty child kicking your chair was bad? In August 2013, 30 adults created the flight from hell when they ran riot on a Ryanair flight from Prestwick to Ibiza, swearing, threatening and even sexually harassing crew in front of other holidaymakers, including families with young children. The men were warned by police about their behaviour before boarding but this didn't stop their drunken rampage, which saw them shouting and jumping on the seats too.
