I'm planning an AONE5, probably starting at the end of March. Requirements are:

1. Maximize flights with F cabins.
2. Maximize mileage.
3. True stops will be at BKK and BOS. FLL would be nice, and there's someone I would visit if I stop there, but it's not necessary. Feel free to eliminate it. Note that my current itinerary does not include JFK/BOS and HKG/BKK segments as they are too short and I feel that they are a waste. I'll just buy those separately.

Current planned itinerary is JNB-LHR-MCT-LHR-HKG-SYD-HKG-NRT-HKG-JFK-ORD-FLL-ORD-MIA-LAX-LHR-NBO. Cost (per Expertflyer) is $9,639, producing a cost of 6.87¢ per mile (including 50% class of service and 100% elite status bonuses).

I'm amenable to buying up additional segments (you can do that, right?) if the cpm is worth it.

I'll be grateful for any suggestions. Thanks in advance.
