Oneworld (Finnair, British Airways and American Airlines) have very attractive summer Business Class fares from Gotenburg (Sweden) to the US right now. These fares do not work in reverse though.
The fare class I earns 125% with most Oneworld programs.
We have seen Business Class fares to be lower in summer and these sales come and go. However this saves $2,000-$3,000 compared to regular fares if you have trip coming up.
If you rather fly Skyteam (Ai France, Delta, KLM) take a look at fares from Stockholm (ARN).
