>> You can do a quick test before boarding an international flight Just curious, how do anticipate this working from a business point of view? If boarding is denied due to a positive test, does the passenger get a refund? If that's the case, won't airlines overbook significantly more than they do today, which in turn will probably increase chaos? On the other hand, if tickets are non-refundable, who would gamble on purchasing an expensive ticket and then be subject to losing it due to a semi-inaccurate test?
