OneWorld elite here, in need of some advice for award travel on Star Alliance.

Would like to travel LON-ROB (via BRU) in biz, return. Route is served by SN. Dates flexible, sometime within the next year. I can transfer a bunch of AmEx points to any of the FFPs that have transfer arrangements with Membership Rewards (US). I believe these are:

KrisFlyer
ANA Mileage Club
Aeroplan

I can go and do all the research myself, but wanted to check here first to see if there was one obvious solution, as it will save me a great deal of time! Will one of these FFPs be best for arranging this kind of award (i.e. lowest mileage cost, lowest taxes, etc.)? I have no miles or status in any Star Alliance FFP, so I'm happy to open a new account with any of the above.

Many thanks in advance, and please let me know if I can help with a OneWorld question for you!
