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 | 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
How long is the flight from Attock to Chicago?
A non-stop flight from Attock (ISB) to Chicago (ORD) 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 345°.
How far is Attock from Chicago?
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 ISB and ORD?
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.
