When even the Thai embassy does not have current info of what is required for travelers to return to Thailand and the Thai govt has abolished CEO's but is still to replace it how can potential tourists make flight bookings to Thailand? Travel agents have been shifting consumer demand for travel to Thailand to other countries. There is no clear policy on entry requirements to Thailand - isolate for 7/14 or just one day depends on who you talk to and with airlines not refunding air fares if the Thai govt does not grant an entry permit why would people book flights to Thailand? Other SE Asia countries have easy to understand entry requirements.so why try to get to Thailand? The answer for me is because it was my home until I could not return because of Covid. Interestingly Thai airways is happy to sell air tickets to Thailand, levies onerous fees for cancellation or date changes and tells potential customers that it is the customer's responsibilities to ensure they have the correct documentation for entry to Thailand. What is the "correct documentation?" Thai airways cannot help!
And as for insurance requirements. Thai insurance companies have unrealistic age caps on policies. Why not just sell policies that cover costs up to the value specified by the Thai govt and nothing else?
