Right from the Flyertalk forums comes this thread on flights from the U.S to Italy for less than $500 bucks from the West coast, and less than $300 from the East coast. The only way to make this hot deal work is to price it through a third-party side such as Priceline or Kayak, then choose AirOne and/or AirOne and United as the carrier. Initially it prices much higher, but after you make your selection, it reprices downward. This takes a little work and patience, but in the end you wind up with a smokin' hot, unbeatable fare to Italy.
