Some random thoughts on your friend's itinerary. Obviously, some are mutually exclusive but with nine spare segments, there is great potential
1. Is there the possibility of spreading the trip over two Qantas FF years to get Platinum status and then make a good start to retaining it?
2. With forthcoming changes mooted and a number here saying that WP status may be harder to obtain, maintain flexibility to adjust the itinerary (or migrate to AA!) when the changes are announced.
3. Why not QF First Syd-JFK and then back to the West Coast?
4. She seems to have dropped Vancouver but there is the genuine First on CX to/from JFK and interesting diversions such as YVR-MEX on JL a couple of times a week albeit not in First.
5. What about a side trip from JFK to BGI?
6. In Europe she had no trips - what about something a bit more exotic than the standard such as Funchal or Amman to see Petra?
Anyway, I see she has booked but maybe these suggestions give you more thoughts.
