Planning to fly from Phuket to Chiang Mai later this month, but all flights pass through Bangkok, and some of the flights are self-transfer (i.e. we have to exit the gate and then check back in/pass through security again in Bangkok). Does anyone know if there will be any chance of being stopped from proceeding to Chiang Mai due to covid travel restrictions? Is there any chance we would be forced to quarantine in Chiang Mai?

Phuket to Chiang Mai with layover in Bangkok? I need to travel to CM for business, but there are no longer any direct flights. From Phuket to CM there should be no quarantine requirement, but will flying through Bangkok cause issues and have them require me to quarantine in CM?
