I'm not sure if this has been asked before, but after the 7 days sandbox program, do we need to retake a pcr rt/fit to fly test for domestic travel ? (BKK to HKT in my case, both are sandbox)
TLDR : Answer Summary
After completing the 7-day sandbox program in Bangkok, you generally do not need to retake a PCR test for domestic travel to Phuket, provided you are fully vaccinated. You will need to present your vaccination certificate to both the airline and authorities upon arrival in Phuket. Additionally, a negative test result within 72 hours can also suffice for entry into Phuket.
