Book early for the best fares: Rome to Florence starts at EUR 19 ($20.50) on Italo if purchased 3 to 4 weeks ahead. Vatican City and San Marino, both independent microstates within Italy, require no separate visa.

Direct flights from New York JFK to Rome run about 8 hours 30 minutes on ITA Airways, Delta, and United. Newark, Miami, Chicago, Boston, Los Angeles, and Philadelphia also have nonstop service to Italian cities. Italy uses the euro, trading at roughly $1.08 per EUR 1.

Leonardo Express to Roma Termini (32 min, €14) departs from inside the terminal every 30 minutes. Regional FL1 trains cost €8 and serve Trastevere, Ostiense, and Tiburtina; useful if your accommodation is near those stations.Official taxis (white, metered) from FCO to central Rome (within the Aurelian Walls) have a fixed €50 fare regardless of traffic.

Rome Climate

Mediterranean climate. Summers are hot and dry (28–36°C, June–August) with little rain and intense sunshine. Heat rarely disrupts flights but can make the terminal uncomfortable. Winters are mild (5–13°C) with rain primarily from November through February. Snow in Rome is rare, occurring once every few years, but when it falls the city and airport are largely unprepared. Even light accumulations cause significant disruption.

Spring and autumn are the most pleasant seasons (15–23°C). Sirocco winds from the Sahara occasionally bring warm dusty air and reduced visibility in spring. FCO has little fog risk and generally good flying weather compared to northern European hubs.
