Rome to Houston (FCO–IAH) — Airlines, Schedules & Connections

Italian passport holders enter the US under the Visa Waiver Program (VWP) for stays up to 90 days. An approved ESTA (Electronic System for Travel Authorization) is required before boarding and costs USD 21. ESTA approval is valid for 2 years or until the passport expires, whichever comes first. Stays cannot be extended beyond 90 days under the VWP. The passport must be machine-readable and include an electronic chip.

Leonardo Express non-stop train runs from Roma Termini to FCO in 32 minutes (€14, no stops). Regional trains (FL1 line) make stops including Trastevere, Ostiense, Tuscolana, and Tiburtina; slower (45–55 min) but cheaper (€8) and useful if you're not near Termini. Trains run every 15 minutes from Termini and every 30 minutes for regional services.Taxis from central Rome have a fixed fare: €50 (within the Aurelian Walls), €55–60 for outer neighborhoods. The fixed rate is mandatory; insist if the driver tries to use a meter. Ride-hail apps (Uber Black, itTaxi) are available but pricier than taxis on this route.

No direct rail from IAH. The METRO bus 102 (IAH Express) runs to downtown Houston's transit center (60–90 min, $1.25). Taxis to downtown Houston cost $50–70. Ride-hails pick up at the designated Rideshare zones outside baggage claim on the lower level.IAH has five terminals (A–E) connected by an underground tunnel with trams. Terminal D handles international arrivals. Rental car agencies are in a consolidated facility adjacent to Terminal C; a free IAH Connector bus runs between terminals and the rental car center. The Galleria / Uptown area costs $35–50 by ride-hail.

Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.

Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.
