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.

Taxis and ride-shares dominate ground transport. A metered taxi to the Strip costs $20–30; to downtown Las Vegas ("Fremont Street area"), $20–25. Ride-shares are comparable or slightly cheaper.Hotel casino shuttles serve major properties. No rail connects the airport to the Strip. Rental car facilities are at the CONRAC facility adjacent to the terminals, accessible by shuttle. Tunnel project (LVCC Loop) does not serve the airport.

Hot desert climate. Summers are intensely hot (38–45°C) with low humidity. Heat itself rarely disrupts flights, but monsoonal afternoon thunderstorms from July through September can produce brief but severe delays. Microbursts and lightning strikes ground aircraft quickly.

Winters are mild and sunny (5–15°C) with rare frost. Snow is unusual but possible in January and February. Spring dust storms (haboobs) can reduce visibility rapidly. The airport sits at 2,181 feet; thin air affects aircraft performance on extremely hot days.
