It's the longhaul QF segment that's driving up your carrier fees... suggest dropping the EYW sidetrip altogether and going JL SYD-HND, overnight stopover, then JL HND-JFK.. JL has surcharges too, but not as bad as QF. It should be approx $325 total in fees with JL on those 2 segments... and you'll rack up way more LPs with a JL code.
