I'm about to purchase a RTW fare on OneWorld through AA. I'm discovering that almost half my EQM will be lost between no credit on CAX, and 50% on QFF. Am going BOS->DXB->PER->SYD->LAX->BOS. This is making it harder to justify spending $6k and having to go through LHR and pay way too much in tax to the crown.

However, I realize this may sound crazy or naive....but...

If I were to simply "stop" in LAX or perhaps SYD, send myself home to BOS on a separate one way ticket, could I "resume" that RTW itinerary and go elsewhere with it later in the year? I assume I would have to get myself back to the last leg on that itinerary, but depending on where I can go next and how much time I have later in the year, I could probably recoup at least some of the EQ miles lost between DXB -> HKG -> PER on CAX, and the rest on QFF lost between PER->SYD->LAX.

Really appreciate and suggestions, insights, advice here. Booking this as a regular multi-city itin on OO has been pricing out at more than double the RTW coach fare....

thx in advance,

Bartonio
