Taking Number-6's recommended USA maximizer routing, and noting your oringal request to visit HGK, SIN, NRT and JFK, you should be able to earn about 2000 QF SC's by routing:
ADL-BNE-AKL-HKG-NRT-HKG-SIN-HKG-LHR-DXB-LHR-SFO-BOS-SJU-DFW-ANC-DFW-JFK-SYD-PER-ADL
This is 20 sectors and I make it 2010 QF SC's and 60,513 flown miles. I'd hate to do it in WHY, but in J or F that would be quite a treat.
