Chicago to Buenos Aires (Ezeiza)
11h 40mgate to gate
The flight from Chicago O'Hare International Airport (ORD) to Ezeiza International Airport - Ministro Pistarini (EZE) covers 9,049 km (5,623 miles) and takes approximately 11h 40m gate to gate for a typical jet.
The route heads south-east on an initial great-circle bearing of 156°, passing near 3.7° N, 72.5° W 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: 9,049 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 11h 14m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 11h 40m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
9,049 km / 805 km/h = 11h 14m airborne
+ 25 min ground = 11h 40m 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 | 16h 27m | 16h 52m |
| Narrowbody jet (A320, 737) | 780 km/h | 11h 36m | 12h 01m |
| Widebody jet (777, 787, A350) | 900 km/h | 10h 03m | 10h 28m |
| Private jet (Gulfstream) | 850 km/h | 10h 39m | 11h 04m |
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 Buenos Aires (Ezeiza)?
A non-stop flight from Chicago (ORD) to Buenos Aires (Ezeiza) (EZE) takes about 11h 40m. The great-circle distance is 9,049 km (5,623 miles, 4,886 nautical miles), flying south-east on an initial bearing of 156°.
How far is Chicago from Buenos Aires (Ezeiza)?
9,049 kilometres in a straight line over the earth's surface — 5,623 miles or 4,886 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 EZE?
This page calculates the direct-line time and distance; it does not track airline schedules. At 9,049 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 40m 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.
