Planning a family trip to Italy for next year and need to book flights out of the NYC area, most likely JFK to FCO. Can you recommend an airline you have flown this route on before? Must be non stop. Looks like options are Alitalia, American Airlines, Delta, and United (but out of Newark). Hoping to book with an airline that offers an upgraded coach/economy option, since we can not afford business/first class. Thanks in advance!
