Two hundred and thirty five people were unable to fly out to Shenyang as scheduled at midnight on Wednesday (September 24) after it was discovered that the radar in the aircraft was not working.
All the passengers were offered free rooms at the Royal Phuket City Hotel.
Because the same aircraft was also supposed to be used on the airline's charter route between Phuket and Tianjin, passengers who arrived for the midnight flight last night (September 25) to that city found that they too would not be able to go home on schedule.
They too were offered free accommodation in Phuket Town.
A Jet Air spokesman said this afternoon (September 26) that the flight to Shenyang took off at 4:30, around 40 hours late.
Rather than delay the Tianjin passengers much longer, another aircarft has been ordered from Bangkok and should, the airline hopes, take off for Tianjin at midnight tonight, 24 hours late.
