Assuming there is still 2 non-QF carriers to validate the Award if QR are lost.On my award QF had ticketed 4 x J LAX SYD AA73.My flight before this was QF12 JFK-LAX....which could only connect to an onward QF flight.They called me to advise AA73 must be cancelled, and offered LAX-SFO-SYD (which had 4 J available) in its place.I said a bit disappointed they confirmed LAX-SYD direct with AA for me, and now I have lost my direct flight.They 'magically' found 4 x J LAX SYD QF12 for me (as NB this is never available via normal release).I was thankful, and asked 'how?'. The helpful QF agent said he 'did something behind the scenes'.Extra taxes, but a good outcome.So, do try and make QF find a solution for you (and not make you rely on the award availability gods).
