Hong Kong  - The widow of a Hong Kong man killed in a car crash as he travelled across Thailand to try to catch a flight out of the country was due to arrive back home Wednesday.

Fung Man-wai suffered only minor injuries in the minibus accident on Monday that killed her husband David Yick Hok-wing and a Canadian man and also left a British woman tourist seriously injured.

Fung and Yik were passengers in a minibus taking tourists from stricken Bangkok airport to the southern resort island of Phuket to try to catch flights out of Thailand when it crashed at 3 am Monday.

Speaking to Hong Kong reporters from her hospital bed in Surat Thani, Thailand, Fung was quoted as saying: "It was simply an accident ... I feel grateful (to be alive)."

The driver of the minibus was arrested by Thai police after the accident for alleged dangerous driving. He later denied claims he had fallen asleep at the wheel.

Fung had been discharged from hospital and was due to arrive back in Hong Kong on a flight Wednesday evening, officials said.

More than 900 Hong Kong people have been stranded in Thailand by the airport sit-in. Four planes chartered by the city's government have brought a total of 212 passengers home so far.

The government has been criticized for failing to let people know about the emergency flights out of Thailand's U-Tapao military airbase which have been 70 per cent empty. (dpa)
