CX has operated a freighter into BNE West on occasion. Dispensation? Or did they operate via CNS or similar? Different rules for freighters?
I think that was a one-off 'proving' flight to show it could be done and to garner a bit of publicity for the owners of the airport. The aircraft flew in to Wellcamp from Sydney and then departed for Hong Kong. I assume they had some kind of dispensation to depart for an international destination from a non-designated airport.
