Best Cheap Airfare

Need to find REAL cheap airfare (under $350) from NYC to anywhere in Europe for June '08. Best site?

Whoever gives me the name of a site that offers the cheapest airfare will get a prize (in addition to being chosen as Best Answer, of course. =) Thanks. Just realized that June is probably a very expensive month to travel, so I'll open my wallet up to $400. (Round trip. =)

1. Which country of Europe? That makes a difference!
2. I`ve found Aer Lingus to Amsterdam on 10 June for about 400$. That`s the cheapest but for one way trip. Check out their website.
3. You can check: http://www.cheapoair.com , you might get some god deals there. Good Luck. Pal.
4. Yahoo FareChase, man! It has the most inexpensive airfare, and it's consistent. I recently used it to book airfare to Paris and I was floored by how cheap the prices were. Good luck and have fun in Ireland, it's real nice there.
