Video / Mark MitchellTravellers, airlines and tour operators had a rollercoaster few days after Thailand reinstated its Covid-19 vaccination entry requirement, only to drop it again just hours later. On Saturday, January 7, Thailand officials announced international visitors would have to provide proof of full vaccination before arriving in the country from Monday, January 9. Around 15 tourists were denied boarding a Turkish Airlines TK64 flight that left Istanbul last night, according to one traveller. One traveller told Barrow over 20 passengers had been turned away from a Kualar-Lumpur flight to Thailand after failing to provide vaccination documentation. One traveller claimed they tried to board a flight following the updated entry requirements but were still asked to show vaccination requirements.
