    Dear thaiembassy,
    we do have a flight from Zurich to Bangkok – booked a long time ago. We now want to make it a Samui+ Stay.
    Unfortunately our airline is not able to include the flight Bangkok – Samui – Bangkok on this booking. Can we book the flight separately, do you have any advice?
    Thanks in advance

      Dear Stefan,
      Good day.
      You need to book the Samui flight included in one ticket only. Your current travel arrangement requires you to quarantine in Bangkok before you can fly to Samui. To avoid it, you nee to contact your airline if they can add the Bangkok-Samui flight in one ticket.
      Thank you.

      Can you advise if Vietnam is on a red list restricting entry to Thailand at the moment?


    • September 13, 2021

      Hi C,
      Good Day!
      Vietnam can enter Thailand under two ways:
      1. Bangkok Quarantine Program (with quarantine)
      2. Phuket or Samui Sandbox Program (no quarantine for fully vaccinated traveler)
      Thank you.

    • September 14, 2021

      Dear Cormac,
      At the moment, Vietnam can enter Thailand through Quarantine program or through Phuket Sandbox.
      Thank you.

    Hello everyone, at Phuket Sandbox you have to arrive before 6pm so that the night is counted. Does the same principle apply to the Samui Sandbox?
    If so, does the arrival time at the airport or the check-in at the hotel count?

    • August 18, 2021

      Dear Julia,
      Yes, that is correct. The Bangkok to Samui flights (2 flights only per day) are limited so it is not difficult to determine whether your arrival is counted as Day 1 or not.
      Thank you.

    I’m quarantining in Bangkok and then hoping to fly to samui, will I have to then do the sandbox when I arrive? I get vaccinated 7 days before I fly to Bangkok.

    • July 16, 2021

      Dear Christian,
      Good day.
      The Samui Sandbox is only applicable to travelers coming from abroad. If you are quarantining in Bangkok already, you will travel to Samui as if you are a resident of Thailand. You can travel on domestic flight and no specific flight. You do not need to stay in an accredited hotel. Just make sure that you meet the entry requirements of Samui for domestic travelers such as COID test before traveling to Samui. Also, Bangkok is a dark red zone so there may be other requirements for entry to Samui or other provinces.
      Thank you.

    Hi there, is it possible to combine this programme with the Phuket Sandbox?
    So for instance we would fly to Phuket, stay there for 8 days in an SHA+ hotel, and then fly Koh Samui to stay in an SHA+ hotel there for the rest of the initial 14 day period?

    • July 16, 2021

      Dear Hugo,
      Good day.
      At the moment it is not possible. You are unable to leave Phuket to go to Samui without completing the 14-night stay requirement in Phuket.
      Thank you.

    Dear Rex,

    Is it possible to first join the Phuket Sandbox for 14 days and travel from Phuket to Koh Samui / Koh Tao / Koh Phangan? Does it require 7 days of Extra Plus Quarantine Hotel stay still? Or it can directly be an SHA+ hotel?

    • July 16, 2021

      Dear Elsa,
      Good day.
      The Samui Sandbox is designed for travelers directly coming from abroad. If you are coming from Phuket, that is a domestic travel already, therefore it is not required for you to stay in an SHA+ hotel in Samui or Extra Plus hotel.
      Thank you.
