Chicago to Luxembourg

8h 56mgate to gate

The flight from Chicago O'Hare International Airport (ORD) to Luxembourg-Findel International Airport (LUX) covers 6,854 km (4,259 miles) and takes approximately 8h 56m gate to gate for a typical jet.

The route heads north-east on an initial great-circle bearing of 47°, passing near 56.4° N, 45.1° 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: 6,854 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 8h 31m.
  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: 8h 56m 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.
6,854 km / 805 km/h = 8h 31m airborne
            + 25 min ground = 8h 56m 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 Chicago to Luxembourg?

A non-stop flight from Chicago (ORD) to Luxembourg (LUX) takes about 8h 56m. The great-circle distance is 6,854 km (4,259 miles, 3,701 nautical miles), flying north-east on an initial bearing of 47°.

How far is Chicago from Luxembourg?

6,854 kilometres in a straight line over the earth's surface — 4,259 miles or 3,701 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 ORD and LUX?

This page calculates the direct-line time and distance; it does not track airline schedules. At 6,854 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.

What should I expect on a 8h 56m 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.
