Chicago to Velika Gorica

9h 59mgate to gate

The flight from Chicago O'Hare International Airport (ORD) to Zagreb Franjo Tuđman International Airport (ZAG) covers 7,704 km (4,787 miles) and takes approximately 9h 59m gate to gate for a typical jet.

The route heads north-east on an initial great-circle bearing of 46°, passing near 57.3° N, 38.2° 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: 7,704 km.
  3. Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 9h 34m.
  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: 9h 59m 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.
7,704 km / 805 km/h = 9h 34m airborne
            + 25 min ground = 9h 59m 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 Velika Gorica?

A non-stop flight from Chicago (ORD) to Velika Gorica (ZAG) takes about 9h 59m. The great-circle distance is 7,704 km (4,787 miles, 4,160 nautical miles), flying north-east on an initial bearing of 46°.

How far is Chicago from Velika Gorica?

7,704 kilometres in a straight line over the earth's surface — 4,787 miles or 4,160 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 ZAG?

This page calculates the direct-line time and distance; it does not track airline schedules. At 7,704 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 9h 59m 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.
