Now, here's where it gets interesting... as mentioned here previously, the current Thailand passes are issued not just for the date you requested, but are valid for entering Thailand as early as 7 days before, or as late as 7 days afterward. This is great for us, because something came up and we need to delay our trip 5 days. The thing is... one of the people in our group is not vaccinated. She qualified for the no-quarantine pass by submitting a RT-PCR test taken less than 72 hours before the originally planned departure - yet her Thailand Pass is valid for 7 days after the originally planned arrival date, just like us vaccinated folks. So by the time we land in Thailand 5 days later than planned, her Thailand Pass will still be valid... but the RT-PCR test it was based on will be over a week old!

Is this a problem? Do we need to somehow update her pass with a newer test closer to the actual flight (or apply for an entirely new Thailand Pass), do we use the existing pass but bring along results of a newer test, or do we forget about the test altogether and enjoy this potential "loophole" in the system?

EDIT: I just noticed that the printable PDF of the TP says "Please note that if you enter Thailand using an RT-PCR test result, your test result must remain valid at the time of departure." Does that just mean that she needs a valid test at time of departure (but could be a newer test also)? Or does it mean that once the original PCR test dies (i.e. becomes more that 72 hours old), the Thailand Pass dies with it (despite the listed expiration date being later), and she needs to apply for a new pass?
