I did a run just like yours a few weeks back.. It was SFO-LAX-NRT-SIN-NRT-JFK-ORD-HKG-SIN-NRT-HNL-LAX-SFO. I am suprised you got HNL in on your trip to JFK. I could not, two HNL layovers are better than one... I got the SIN-JFK for like $470 USD with a 15% coupon.. Now that I think back I should have done a few more SIN-JFK runs, well thats because I was in First on NRT-JFK, yet it wasn't too long.. I hope you enjoy your trip, and I thought I was the only one to do one like this. You should have seen the look on my buddies face at the NRT RCC when I asked for my BP's for SIN-JFK, the next morning. You see, I landed in SIN, and took off the morning I landed! But I spent a few days in NYC though.
