So Thailand just removed the pre flight Pcr test starting April 1. Good news. However testing day 1 is still here and will be for awhile. I’m presently in quarantine and didn’t have to be. My suggestion is you spend a bit of money a couple weeks before your trip for a Pcr test. If neg great. But if + (heaps of asymptomatic + cases) you have time to get a Certificate of Recovery/ medical cert so if you test again positive in Thailand you won’t have quarantine. Just my thoughts.
TLDR : Answer Summary
Thailand has removed the pre-flight PCR testing requirement as of April 1. However, travelers must still undergo testing on day one of arrival. If travelers have a negative PCR test before their trip, it is advisable to obtain a Certificate of Recovery in case they test positive upon arrival, to avoid quarantine. Additionally, the discussion includes the requirement to stay in a hotel for the first night and subsequent rapid antigen tests, alongside insurance requirements.
