It could've been incubating already before I took off and still didn't show up on the pre-departure test.
Not sure about Thailand, but there are jurisdictions like the USA & Singapore than don't require testing at all for people with documented prior covid infection, for this reason.
One thing to keep in mind is that the Thai Day 1 test pushed the swab quite far up my nose and down my throat, and that might trigger a positive result - you may want to make sure you get a through swabbing to see if that is also negative.
