Davvidd I also wondered this too. I checked in on June 19th with AC staff at Seatac Airport, I spent almost an hour where they checked every travel document that I needed thoroughly including my COVID-19 test result document and my online HR government QR for entry to HK and they found that all my documents were in order and valid before they allowed me to board AC flight AC8090 to YVR. If my documents were inadequate in any way, why did they let me board after spending almost an hour checking all my documents? I would have prefered to be denied boarding in Seattle because the costs and inconvenience at that point is minimum.
