How should I use my Membership Rewards points for an Economy redemption from Melbourne to Europe?

Hello all,

I would like to fly to Europe from Melbourne for 4 weeks from mid August to mid September. I currently hold 2 Amex cards: Platinum Reserve and Platinum Edge for which I have accrued 115000 points collectively. I have also a supplementary AMEX platinum charge card allowing me access to Starwood Preferred Guest and LeAccor.

I am after some assistance as to what the best frequent flyer program to transfer my points to in order to fly economy for the least amount of points from Melb to Western Europe (not sure as to where I’ll fly in to Europe first).

Any assistance would be greatly appreciated.
