Paris (Roissy-en-France, Val-d'Oise) to Dulles
8h 07mgate to gate
The flight from Charles de Gaulle International Airport (CDG) to Washington Dulles International Airport (IAD) covers 6,198 km (3,851 miles) and takes approximately 8h 07m gate to gate for a typical jet.
The route heads west on an initial great-circle bearing of 292°, passing near 51.5° N, 41.5° W at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 6,198 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 7h 42m.
- 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 07m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
6,198 km / 805 km/h = 7h 42m airborne
+ 25 min ground = 8h 07m 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.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 11h 16m | 11h 41m |
| Narrowbody jet (A320, 737) | 780 km/h | 7h 57m | 8h 22m |
| Widebody jet (777, 787, A350) | 900 km/h | 6h 53m | 7h 18m |
| Private jet (Gulfstream) | 850 km/h | 7h 18m | 7h 43m |
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 Paris (Roissy-en-France, Val-d'Oise) to Dulles?
A non-stop flight from Paris (Roissy-en-France, Val-d'Oise) (CDG) to Dulles (IAD) takes about 8h 07m. The great-circle distance is 6,198 km (3,851 miles, 3,347 nautical miles), flying west on an initial bearing of 292°.
How far is Paris (Roissy-en-France, Val-d'Oise) from Dulles?
6,198 kilometres in a straight line over the earth's surface — 3,851 miles or 3,347 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 CDG and IAD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 6,198 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 07m 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.
