An Air India jet was ordered to park at an isolated area of Suvarnabhumi airport on Wednesday night after a bomb threat, an airport official said.
Air India flight AI 332 from Delhi landed at Suvarnabhumi at 7.10pm and air traffic controllers directed the pilots to taxi the plane to an area away from other jets for safety reasons, Chadanisa Chumnanvej, deputy general manager of Suvarnabhumi airport in charge of operations, said.
Authorities activated an emergency plan and safely evacuated all 231 passengers, one of them a child, and 10 crew members from the aircraft to begin checking for a bomb, Mrs Chadanisa said.
Police from the Explosive Ordnance Disposal unit are checking all pieces of luggage including those loaded on the aircraft, she added.
At this stage the result of the check remains unknown.
Air India uses a Boeing 787 dreamliner for the flight, according to the flightaware.com. The plane left the Indian capital at 2.05pm local time.
