MilesBuzz! - Trans-Atlantic J or F Promos?

Which airlines, if any, are offering any special bonuses for full C or F trans-atlantic travel this month?

I hopefully need to go to ARN next week, and am considering BA, AA and others for the BOS-Europe segment.

Other potentially attractive possibilities include: Swiss & Luftansa.

Among the rewards I am not interested in are free coach tickets (which can't be upgraded).

Not sure of any bonuses per se, but I know that NW is offering dirt cheap J and C class travel to Europe as long as it involves a connection through Amsterdam:

The restrictions are pretty tight so it might not be of any use.
