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 | 23h 28m | 23h 54m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 33m | 16h 58m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 21m | 14h 46m |
| Private jet (Gulfstream) | 850 km/h | 15h 11m | 15h 36m |
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
How long is the flight from Nairobi to Chicago?
A non-stop flight from Nairobi (NBO) to Chicago (ORD) takes about 16h 27m. The great-circle distance is 12,909 km (8,022 miles, 6,971 nautical miles), flying north-west on an initial bearing of 317°.
How far is Nairobi from Chicago?
12,909 kilometres in a straight line over the earth's surface — 8,022 miles or 6,971 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 NBO and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,909 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 16h 27m 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.
