Thanks Christep an excellent option and dropping out ORD which is not needed buys me another sector. I'm now looking at a slight modification to the effect that I throw an overnight to SEA and back for mileage run while in the US. Looks like this now:

AKL-MEL-PER-HKG-SEL,HKG-NRT-DFW-YVR-DFW-LAX-LHR-HEL-HKG-PER,MEL-AKL

Also changed to HEL-HKG-PER because AY have a code share on the Perth leg and being in the AA program much better earning than the QF or CX flight # options^
