I could successfully do an oneway redemption for a QF flight (AKL-MEL) in Y for 2 persons. Total cost for 2 was 111,50 NZD plus 50.000 Qmiles. I also wanted to book a QF redemption MEL-BME-HVB but the system only allows for 2 seaparate redemptions MEL-BME and BME-HVB which makes it far too expensive. End of last year I was able to get a redemption for ADL-MEL-HBA in "one piece", so I am not sure why this is not possible for other routings with a stop in between.
