Beware the idea that another ONE WORLD partner can do any route " on BAs behalf". If they fly it they do it for themselves,- not BA and BA has in reality withdrawn from that particular market. BA will receive a small percentage commission if they code share it but that's it. It's " game over" for BA in Melbourne and their network in Australia has shrunk to just one city- Sydney. In the Far East it has also shrunk very considerably despite it being the fastest growing market in the world. BAs problem is that, with no additional long haul aircraft on order, the only way they can serve the new destinations or increase frwquencies to others is either by tightening up of aircraft rotations to avoid long layovers and deleting other destinations entirely, or reducing frequencies.
