I'm wondering if an AONE might be a useful (even economical?) solution to premium travel in what might shape up to be a high-travel year. We have some friends in Africa this year, family and friends in the states, and want to take a trip to Oz in 18 months or so. So here's what I'd really like to do:
Go to MRU for a bit of sun in the winter/early spring (say, April 08). I would either cash in miles for that trip or just buy our tickets.
Then, start the AONE: MRU to JNB
JNB to LUN (would have to buy this one, just a one-way on maybe?)
then back home LUN to LHR.
While home in London, have a few trips over several months courtesy of the AONE: Maybe LHR-ATH-LHR, LGW-KEF-LGW.
Then next autumn, back to the states to see some family. LHR-SEA, SEA-ORD-MCI, MCI-ORD-YYZ, YYZ-NYC.
Back home to London on a cheap-ish purchased BA ticket, say JFK-LHR on WT+ maybe, then return to JFK in February/March 2009.
Then resuming the AONE: JFK-LAX, LAX-SYD, SYD-LHR.
I understand that I need to ticket the final leg to someplace like DAR, which should let me "transit" at LHR and just abandon the final leg. (Is that right?)
I've punched it into the planner and it comes up inexplicably as five regions (though I'm counting four: Africa, Europe, NA, SWP). It must be counting Asia even though I'm not stopping there? (And is there any way to avoid that?) Also, it seems like in some variations when I put it in I get an error along the lines of "too many flights to/from the UK"; but I couldn't find reference to a rule about that.
Is there anything else I need to think about about this? Is there anything I'm missing or doing wrong? Any other ways to economise? How do folks get to places like MRU to start the ticket?
Finally, I was thinking of booking AONE vs. DONE primarily because I understand that there's very limited availability of D tix on some routes (esp. to OZ) rather than because we have to travel first (though it would be nice

). Does A book into J allocations for biz class seats if there are no first seats left? The long and short of it is we don't want to be stuck doing these long-hauls in Y.
Any and all advice is very welcome!
