This may not answer your question ...

North West,a SkyTeam member, is partner with MH. I mention this since you've said you do most of your flying with MH. Further, Continental has partnerships with many airlines. So, you do have quite a lot of choices for your trip across the pond to the US.

At least, you don't have to start form scratch since you have elite status within SkyTeam. Perhaps only transfer your allegiance to another airline within the alliance.
