Check out this post by View from the Wing who wrote about an amazing deal going on. Business and First Class flights, from Europe to US for $80 or less. You may need to experiment with a few booking sites to find one that will allow you to use a US credit card, and get this offer which is priced in Danish Kroner.
Check out that article for detailed info. Dans Deals first broke out the news and then Business Insider published it as well. Deal of the year without a doubt.
Update
The deal seems dead. United caught on and now they are pricing their tickets is USD and not in Kroner, and also at the regular price and not at the insanely low prices advertised above. Denmark is also off the list of countries when you enter an address at United.com. Hopefully they will honor the tickets that were already bought by those lucky few.
