Paris (Orly, Val-de-Marne) to Paris (Roissy-en-France, Val-d'Oise)
28mgate to gate
The flight from Paris-Orly Airport (ORY) to Charles de Gaulle International Airport (CDG) covers 34 km (21 miles) and takes approximately 28m gate to gate for a typical jet.
The route heads north-east on an initial great-circle bearing of 25°, passing near 48.9° N, 2.5° E 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: 34 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 3m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 28m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
34 km / 805 km/h = 3m airborne
+ 25 min ground = 28m 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 | 4m | 29m |
| Narrowbody jet (A320, 737) | 780 km/h | 3m | 28m |
| Widebody jet (777, 787, A350) | 900 km/h | 2m | 27m |
| Private jet (Gulfstream) | 850 km/h | 2m | 28m |
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 (Orly, Val-de-Marne) to Paris (Roissy-en-France, Val-d'Oise)?
A non-stop flight from Paris (Orly, Val-de-Marne) (ORY) to Paris (Roissy-en-France, Val-d'Oise) (CDG) takes about 28m. The great-circle distance is 34 km (21 miles, 18 nautical miles), flying north-east on an initial bearing of 25°.
How far is Paris (Orly, Val-de-Marne) from Paris (Roissy-en-France, Val-d'Oise)?
34 kilometres in a straight line over the earth's surface — 21 miles or 18 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 ORY and CDG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 34 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.
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.
