I was just thinking;

If you can fly with a letter of recovery and no test. And, you can enter Thailand without a negative test if you have a positive one and a letter of recovery, why would you still meet to do Alternative Quarantine or Sandbox?

Or can you not use a letter of recovery to do AQ and Bluezone?

Cuz if you can, and the test just keep coming back positive (which is why you have the letter) then what?
