Long story short. Am Qantas Life time gold (OW sapphire) and platinum(OW Emerald). Have just renewed QFF platinum and am about to take an AA tickets F trip - SYD-LAX-DCA-BOS-DFW-SYD and am thinking that an AA challenge may get me a long way with that trip. Majority of travel is with QF domestically and across Asia in Y.

Does the brains trust think I am better off moving to AA or stay with QFF? This flight alone would give me 870 QFF status credits (platinum renewal is 1200).

As always your thoughts are appreciated...
