I am a US citizen and I am set to depart Bangkok back to return back to Washington DC via Japan on JAL next week. I understand that I need to provide a RT-PCR test that is under 72 hours old. Is this still true or have the exit requirements changed?
TLDR : Answer Summary
As a US citizen departing Bangkok for Washington DC via Japan, the requirements for COVID-19 testing have changed. Currently, the USA only requires a Rapid Antigen Test (ATK), which must be taken within 24 hours prior to departure. However, some airlines, like Japan Airlines (JAL), might have specific requirements, so it is advisable to check with the airline for the latest updates. It seems that a RT-PCR test is no longer necessary unless specified by the airline or health regulations at the destination.
