Chicago to Attock
14h 34mgate to gate
The flight from Chicago O'Hare International Airport (ORD) to Islamabad International Airport (ISB) covers 11,389 km (7,077 miles) and takes approximately 14h 34m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 16°, passing near 77.2° N, 11.0° E 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: 11,389 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 14h 09m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 14h 34m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
11,389 km / 805 km/h = 14h 09m airborne
+ 25 min ground = 14h 34m 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 | 20h 42m | 21h 08m |
| Narrowbody jet (A320, 737) | 780 km/h | 14h 36m | 15h 01m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 39m | 13h 04m |
| Private jet (Gulfstream) | 850 km/h | 13h 24m | 13h 49m |
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 Attock?
A non-stop flight from Chicago (ORD) to Attock (ISB) takes about 14h 34m. The great-circle distance is 11,389 km (7,077 miles, 6,150 nautical miles), flying north on an initial bearing of 16°.
How far is Chicago from Attock?
11,389 kilometres in a straight line over the earth's surface — 7,077 miles or 6,150 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 ISB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,389 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 14h 34m 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.
