Always be careful what you wish for! There were many people at Ansett who thought that SQ was going to be the white knight and fix all the problems, after all they were a big successful international carrier. SQ are indeed a big successful international carrier but whenever they stray outside their own territory they have a dismal record.
Whether its a complete lack of understanding of politics in Australia and NZ or an inability to influence decisions behind the scenes I don't know. When it comes to successful offshore partnerships they just don't have the runs on the board.
