...if Singapore Airlines was dropped as a partner airline of which may happen now then I'll jump ship.
It will be interesting which airlines offer any Japan flights if that route will open up within the next 6 months given talk of the bubble.
Maybe have both SQ KF and (Air)NZ Airpoint membership, (AirNZ Airpoint dollars), and just put your flight points/miles credit to each, depending on where you have/want to fly to.
This is what I have done, set up KF which I have about 10,000 miles with, having credited some (Air)NZ flights to, and the former MEL - WLG, one of these to the KF system, and have joined the (Air)NZ Airpoint dollars system, ADL - AKL (overnight), most days can be done direct, then AKL - Japan with (Air)NZ.
Or ADL - SIN and a few hours transit, then SIN - Japan.
PER - NRT is still possible, if you want to go that way, putting in "your" (Air)NZ Airpoints dollars FF #, or SQ KF FF#, flying ANA.
Or with QF, ADL - east coast Au - then MEL/SYD/BNE - Japan.
Depends on where in Aust you live, of course.
As others have mentioned, waiting to see what Bain does with VFF, am keeping FB points in FB, not transferring.
Also Bain does not seem to be doing much serious "damage control", they are keeping so quiet, and not fighting back against the speculations swirling around.
