Is the flight to Italy turbulent?
Cruise is smooth most of the way, but transatlantic flights to Rome and Milan cross the North Atlantic jet stream, which can cause clear-air turbulence — especially in winter. The descent over the Alps into Milan or the Apennines into Rome can add brief mountain-wave turbulence.
When is the smoothest time to fly to Italy?
Late spring through early autumn (May–September) generally has a weaker, more northerly jet stream and calmer air over the Atlantic. Winter (November–March) brings the strongest jet and the most clear-air turbulence on transatlantic routes.
Why is there turbulence over the Atlantic?
The North Atlantic jet stream — a fast river of air at cruise altitude — creates wind shear at its edges that can jolt an aircraft without warning (clear-air turbulence, or CAT). It is strongest in winter and on the eastbound US→Europe leg, which rides the jet. Pilots change altitude to find smoother air, but CAT is invisible on radar, so it is the main reason to keep your belt on.
Where should I sit on a flight to Italy?
Over the wing, near the aircraft's center of gravity, gives the steadiest ride. Keep your seatbelt fastened even when the sign is off — clear-air turbulence over the Atlantic can appear suddenly. Overnight eastbound flights often cross the jet stream while you are sleeping, so belt over the blanket.
