If you would have wanted to get a proper response, then you should have at least tried to share more on your preferences, e.g. part of Europe, type of flight, class of travel, length of stay, etc.
Anyway, I am assuming you would travel in economy on a non-stop flight and stay there for seven nights. The top options as of now seem to be:
767 - $1,212
767 - $1,241
747 - $1,252
Keep in mind that it is too early for such a booking now - by then you will most certainly have changes in fares and potentially in aircraft, routes may also be dropped and new appear.
