I have enough krisflyer miles to book ADL- Auckland redemption on Air new zealand. When I try and enter this online it always says there is no availability. Do I need to make a call to the call centre to book an Air new Zealand redemption flight, or if it is not coming up online is it because there is no reward bookings available?? I can do dummy booking on Singapore Airlines flights with lots of availability but I don't want to go to Singapore!
