I went in on a 60 TR, went for my 30 day extension and they offered me a 60 day covid, I could stay an extra month but not 2 so I was fine with that. They didn’t ask about my ticket or covid insurance (that was 90 days)
There was a lot of people confused and thinking it was the time of the test but simply not true per the actual wording, if they had wanted the test to also be within 72, as other countries or airlines have done, the wording will state that. Issued/reported =/= time of the test taken
