Yes ... as of midnight tonight Hong Kong time, the US moves to 'Group A', thereby requiring pax from US to undertake 21 days hotel quarantine. Unsure how/if this affects US crew, as normally you are required to quarantine in your hotel room until your departure flight. So nothing has changed in that respect. I live and work here ... currently 12 days into 14 days hotel quarantine for doing a single pax flight back from the UK;/
