I am currently in the SAS Eurobonus program, but since I recently moved to the US (NJ) I thought it might be optimal for me to switch to another Star Alliance program instead of the one with SAS.

I don't quite know my flying pattern that well yet. I expect to make an occasional fligth to CPH from EWR, but expect most travel to be within US but also some to other European destinations than CPH. Most flying will be economy class. I expect to be traveling maybe around twice per month and will probably be redeeming for flights rather than upgrades.

Any recommendations?
