Going to BKK in a couple of weeks time.
Need some clarification from bros who had recently visited BKK.
I was under the impression that LOS is given the all clear for visitors going there and no longer require quarantine or vaccination certificates.
I had booked my flight tickets on Scoot and flying out from Changi to BKK. And then I received email asking me to go for pre-flight covid19 testing 3 days before boarding my flight.
Why does Scoot has this requirement? I thought since Thailand no longer require testing to enter so we no longer need to have vaccination cert rite?
Can any recent traveller to BKK share their experience?
TQ
