It's getting cheaper and cheaper to fly to VCE!
I just checked AirHero.com and they have AA flying JFK-London-VCE for $460.45 (but this requires a change of airports in London).
I think it is worth the extra couple of dollars to do it JFK-BRU-VCE for $463.74. (On the itinerary I checked, Nov 17-18, you would have to fly back through London.)
They have the Delta direct flight for $515.75 but if that fare gets sold out, you might want to buy your ticket from Alitalia (same metal) for $525.50.
