Singapore Airlines has confirmed that there was a bomb threat in one of its flights which originated from San Francisco to Changi Airport, TODAY Online reported Sunday.

According to the report, flight SQ001 arrived and landed safely at the airport this afternoon, but disembarkation was delayed until around 1.30pm.

“We regret we are unable to provide details, as it concerns security,” said SIA in a media statement as quoted in TODAY, adding that the matter was referred to the authorities.

Passengers also had to wait for nearly two hours to collect their baggage, but remained calm.

“We were held on the tarmac … for about 20 minutes. The captain then made the announcement that the gate was changed,” said a passenger only known as Mr Hoe.

“We were then parked at some remote area near the airport, and no further information was given, apart from waiting for air traffic control instructions.

“At approximately 1.10pm, the captain made the announcement that the plane will be held on the tarmac, and we would be ferried to the terminal by airport bus due to security concerns.

“I thought the captain was handling the situation well. No one was panicking on board. We actually didn’t know anything, and everyone thought it was just a normal delay until the announcement was made at 1.10pm. Everyone still remained calm.”
