Have an opinion question here, hopefully relevant to the thread: Today I received a positive COVID test (I'm mildly symptomatic) in Tbilisi. I have TK flight for Monday that runs TBS>IST>JFK. I'd like to hold off on trying to change the flight on the off-chance I test negative one day before the flight, but also am worried that it might leave me in a lurch with TK and trying to get ahold of them at the last minute. Would people recommend making the change now, or can I wait?
