@hioctane FYI, all scaremongering but the whole plane doesn’t go into quarantine. Only close contacts (within meters) go to quarantine. Although, how many meters is not clear. Positive goes to hospitals/hospetals and negative goes to ASQ.
within meters - one row of seating is 10 people. Many flights wont be full but the risks multiply with the number of 'near' passengers. Many people will be doing two legged flights etc... As you said in your reply 'how many meters is not clear'. That's the reason for the posting. This is not scaremongering. As an adult you can take your changes and see what happens. If a member of crew who has been serving your section of the plane tests positive, that might fall within your definition of close contacts (within meters).
