Geoffrey Kitchen, 73, died during the flight after suffering a suspected heart attack. The musical director’s family said the trip had been planned as “the holiday of a lifetime”.

A total of 104 patients were taken to hospitals and clinics in Bangkok, after the plane, carrying 211 passengers and 18 crew, made an emergency landing at Suvarnabhumi Airport.

Fifty-eight patients are being treated in three hospitals across the city, Samitivej Srinakarin Hospital said in a statement.

The hospital confirmed 20 patients, including six Britons, remain in Intensive Care Units (ICUs), while a further 38, among them nine British nationals, remain in less acute inpatient care.

Others in ICUs include six Malaysians, three Australians, two Singaporeans and one person each from Hong Kong, New Zealand, and the Philippines.

Among the British travellers injured was 22-year-old Mia Stevenson, who told how she was thrown headfirst into the aircraft’s ceiling.
