Cheapest airfare from US to Italy?

Don't fly to Turin airport it is usually more expensive. Check flights to Milan Malpensa International airport (MXP). There is an 8 or 10 euros bus from there to Turin every hour or so. It is about an hour ride. Usually the cheapest routes are from New York. After checking sites like Orbitz (this is my favorite one because you can look at a matrix of different departures arrivals days possibilities) and having tried different dates also make sure to check airlines sites which sometimes have special offers. In particular don't miss British Airways and Alitalia. I hope this helps.
