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.

|---|---|---|---|
| Turboprop / regional | 550 km/h | 14h 28m | 14h 53m |

Questions
How long is the flight from Tunis to Chicago?
A non-stop flight from Tunis (TUN) to Chicago (ORD) takes about 10h 18m. The great-circle distance is 7,953 km (4,941 miles, 4,294 nautical miles), flying north-west on an initial bearing of 309°.
How far is Tunis from Chicago?
7,953 kilometres in a straight line over the earth's surface — 4,941 miles or 4,294 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 TUN and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,953 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 10h 18m 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.
