Presently planning on crediting the lot to QF

By my calcs on tier credits I qual for Gold OW Sapphire on the first landing in LHR and Platinum OW Emerald on landing in ANC, ending with 1980SCs back in Syd (ie 580 in excess of what I need).
Then another 670SCs already locked in for next years from the Aus/Asia legs.

My travel profile is primarily within Australia, and not much domestic US so the AA stamps, upgrades etc don't really help - although obvously the better redemption rates on AA (and lack of fuel surcharges) is tempting.

Any comments as to what others would do in this situation would be appreciated.
