So, for all of you guys, what are the cheapest but also feasible and convenient bookings for a RWT award these days?

ex-CAI with BA? (but surcharges?)
ex-S.Africa with ?
ex-TYO w American?

What is the best combination of affordability and convenience in booking and with whom from the above three? I don't mind originating in any of the three, but convenience would include not having to be physically present in location to book.

How many AA EQMs and EQPs could a reasonably well designed 16-segment DONE4/5 RWT (in business) produce? I assume these could be spread into two calendar years (say you start in the summer) and count towards two different years' elite qualification periods, right?
