Just got 2 x PER-HKG-JFK-YVR, YVR-JFK-HKG-PER in J on CX - Jan/Feb 2015. US$208 + 110k each. I tried for MEL-PER legs as well, but got knocked back on MPM. I was quite prepared for this, so will call again later & add separate flights for another 30k each. Got a good agent & had the whole thing ticketed in 20 mins. I was after anything that would give me 2 weeks in Whistler in Jan-Mar next year, & it took me 4 days to find this routing.
I could have done SYD-ICN-LAX with OZ with LifeMiles, but it would have cost too much for the add-ons at either end. Other than that, I couldn't find anything that would get both directions with the right timings.
