I will be travelling in December

I have being to FCO before. But I don't know what other European cities that can earn good miles ( I don't want SVO as I don't particularly want to goto Russia).

SJO seems to be a bit too far (But i can understand about that mileage part).
As after this trip I can maintain my Gold MPO, hence an extra 2000miles is not that important.

Any more suggestions??

Thanks
