Update: It appears the deal is now expired and these fares are not longer available.
Via Flyertalk, there is a super cheap fare on Brussels Airlines for a roundtrip flight from New York to Sofia, Bulgaria over Christmas 2016. The best price looks to be $268 including all taxes and fees.
This could be a cheap way to spend Christmas in Europe this year and you could easily buy a cheap flight within Europe onece over there.
Quick notes: Other dates may be available, but I did not do extensive searching as I’m just heading out the door. Share below if you find other dates/routes on this deal.
You can find this deal at CheapOair, but book quickly because the deal is sure to be gone soon!
