Rome to Los Angeles

13h 06mgate to gate

The flight from Rome–Fiumicino Leonardo da Vinci International Airport (FCO) to Los Angeles International Airport (LAX) covers 10,203 km (6,340 miles) and takes approximately 13h 06m gate to gate for a typical jet.

The route heads north-west on an initial great-circle bearing of 321°, passing near 61.6° N, 59.7° W at its midpoint.

How this is worked out

  1. Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
  2. Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 10,203 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 12h 41m.
  4. Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 13h 06m gate to gate.
  5. Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
10,203 km / 805 km/h = 12h 41m airborne
            + 25 min ground = 13h 06m gate to gate

The same route, plotted on a world grid

The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path looks bent; on a globe it is straight.

Flight time at different cruise speeds

Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.

Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions this plate answers

How long is the flight from Rome to Los Angeles?

A non-stop flight from Rome (FCO) to Los Angeles (LAX) takes about 13h 06m. The great-circle distance is 10,203 km (6,340 miles, 5,509 nautical miles), flying north-west on an initial bearing of 321°.

How far is Rome from Los Angeles?

10,203 kilometres in a straight line over the earth's surface — 6,340 miles or 5,509 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.

Is there a non-stop flight between FCO and LAX?

This page calculates the direct-line time and distance; it does not track airline schedules. At 10,203 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.

What should I expect on a 13h 06m flight?

Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.

Airport coordinates from OurAirports (public domain). Distance is a great-circle calculation; flight time uses the model described on the method page. Flight times are great-circle estimates for planning only — always check the airline's published schedule.
