I am surprised that QF does not get ahead of the action when they find it necessary to downgrade a pax who has a confirmed higher class booking. They cannot possibly believe that any pax would be happy about being downgraded in the absence of appropriate compensation. In our case our direct CNS-CBR flight J class was cancelled and we were put on flights via BNE with BNE-CBR not having any J class seats available. It took 4 extended phone calls until an offer was made of 2,500 points each. My sense is that they just expected us to go away.
