Screened on arrival?? The issue is that a DXB-EDI-NCL drop would see EDI departing pax mixing with inbound pax out of DXB still on biard for NCL who had been cleared to (allegedly) lower standards. The workaround is a costly DXB-NCL-EDI-NCL-DXB.....
I appreciate that most contributors are discussing theoretical possiblities, but before we create an urban myth, Is there any evidence that any double drops are being considered?
