Just following up on this - I can confirm that (after spending the last 50 mins on hold while the AA agent talked to the rate desk with them trying to understand why the system kept splitting the booking into two awards Intra SWP and SWP-MEI) that it IS POSSIBLE!!! Had to be entered manually by the rate desk to override the system so YMMV but I can confirm it can be done. (Hopefully not speaking too soon as it will only ticket tonight but they have taken the grand total of $156 in taxes from me - outrageous

)
I am stoked as have just landed two F Class PER-SYD-AUH-CAI for Feb next year on the A380 for 60k each. Unbelievable value and thanks to you all for your valuable posts that made it come together.
Now if AA can just figure out a solution to the complete lack of F/C availability on the US-SWP route I'll be even more in awe. I reckon all they need do is allow a Transit without stopover in Asia 1 or 2 to sort it all out - plus it encourages use of their hard product on long haul which surely must be of benefit to them vs having to pay QF for long haul award seats.
