I've read that "visa exemption" tourists still must get a COE--or now, register with some new online system.
However, at least one government Web site merely indicates that visitors must have COVID insurance, one night prepaid in a government hotel to await test results and a return ticket.
Do you know if this information has to be approved by COE, etc., before you board a flight, or must you simply present these documents to Thai immigration?
Thanks in advance.
TLDR : Answer Summary
Visa exemption tourists traveling to Thailand are required to obtain prior approval either through the Certificate of Entry (COE) or the new Thailand Pass, depending on their flight date. Before November 1st, COE approval was necessary to board the flight, while bookings made after November 1st must have Thailand Pass approval. All relevant documents, including COVID insurance and details regarding accommodations, must be approved before boarding to avoid issues with immigration upon arrival.
