The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it 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 | 15h 57m | 16h 22m |

Questions
How long is the flight from Chicago to Spata-Artemida?
A non-stop flight from Chicago (ORD) to Spata-Artemida (ATH) takes about 11h 19m. The great-circle distance is 8,770 km (5,450 miles, 4,736 nautical miles), flying north-east on an initial bearing of 48°.
How far is Chicago from Spata-Artemida?
8,770 kilometres in a straight line over the earth's surface — 5,450 miles or 4,736 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 ATH?
This page calculates the direct-line time and distance; it does not track airline schedules. At 8,770 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 11h 19m 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.
