Your routing is highly incompatible with a good F experience; most of the flights either don't have F, have an inferior F (sometimes worse than J), or have very high demand for F (making it impossible to get 2 F awards on the same flight). Either switch to J (which is better than F was not so many years ago -- flat beds in J now, for example, better than F seating was a decade ago). Or change the routing to be more realistic for F (e.g. SYD-HKG-YVR-JFK-LHR-IST-LHR-HKG-SIN-SYD). Presuming you aren't Platinum with QFF there is little chance in getting some of those awards on specific dates (you often need flexibility of a month or 2 to get F award seats). In practice RTW F awards are impossible now for 2 people without high FF status (many flights only have 1 F award seat, and require status to get a 2nd F seat released, for example). J is considerably easier and it looks like most of your routing is in J in any case.
