Bangkok airport's general manager said the passenger who died was a 73-year-old British man.
In a rare incident, a passenger has been killed and 71 others suffered injuries due to severe turbulence on a flight from London to Singapore. The death has been confirmed by Singapore Airlines.
In a statement, Singapore Airlines said flight number SQ321, which took off from Heathrow Airport in London on Monday and was headed to Singapore, "encountered severe turbulence" en route. The aircraft was diverted to Bangkok's Suvarnabhumi International Airport, where it landed at 3.45 pm (local time) on Tuesday.
The plane - a Boeing 777-300 ER - had 211 passengers and 18 crew members on board.
Kittipong Kittikachorn, the director of Suvarnabhumi Airport, said the passenger who died was a 73-year-old British man, according to news agency AFP. Most of the injuries were caused by blows to the head, Kittipong said.
Bangkok's Samitivej Srinakarin Hospital said 71 people had been sent for treatment, six of whom suffered injuries.
Offering its condolences to the family of the person who died, the airline said, "We can confirm that there are injuries and one fatality on board the Boeing... Our priority is to provide all possible assistance to all passengers and crew on board the aircraft. We are working with the local authorities in Thailand to provide the necessary medical assistance, and sending a team to Bangkok to provide any additional assistance needed."
Experts said such injuries usually happen when passengers are not wearing a seatbelt and the pilot has not been able to give an advanced warning because information from the weather radar does not indicate any turbulence. In such cases, passengers can be thrown around in the cockpit, which may lead to injuries.
In May last year, turbulence had led to several passengers being injured on a Delhi-Sydney Air India flight.
