Another question is what are Qatar doing if the stopover length is meaning it's very hard to actually fulfil the test requirement for countries that stipulate a time window from entry into the country as opposed to from embarkation time (actually I think this is very rare, most countries I have seen USA/Turkey etc stipulate time window is from departure or first departure point)
I wonder if QR are letting pax board on the condition they do a test in DOH, or are just denying boarding?
