Chicago to Addis Ababa

15h 33mgate to gate

The flight from Chicago O'Hare International Airport (ORD) to Addis Ababa Bole International Airport (ADD) covers 12,181 km (7,569 miles) and takes approximately 15h 33m gate to gate for a typical jet.

The route heads north-east on an initial great-circle bearing of 57°, passing near 45.6° N, 8.8° W at its midpoint.

How this is worked out

  1. Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
  2. Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 12,181 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 15h 08m.
  4. Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 15h 33m gate to gate.
  5. Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
12,181 km / 805 km/h = 15h 08m airborne
            + 25 min ground = 15h 33m 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.

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 Chicago to Addis Ababa?

A non-stop flight from Chicago (ORD) to Addis Ababa (ADD) takes about 15h 33m. The great-circle distance is 12,181 km (7,569 miles, 6,577 nautical miles), flying north-east on an initial bearing of 57°.

How far is Chicago from Addis Ababa?

12,181 kilometres in a straight line over the earth's surface — 7,569 miles or 6,577 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 ADD?

This page calculates the direct-line time and distance; it does not track airline schedules. At 12,181 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 15h 33m 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.

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.
