Cash in your skyteam miles and come over to *A - you'll have no regrets...
I am a UA Mileage Plus gold flyer (but rarely fly UA) as my points never expire, if there is activity on the account without an 18 month lull...
LH, SQ and LX will serve you well to the US, no more CDG for you... What a painful transfer point, it is...
Cheers,
