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 | 11h 00m | 11h 26m |
| Narrowbody jet (A320, 737) | 780 km/h | 7h 46m | 8h 11m |
| Widebody jet (777, 787, A350) | 900 km/h | 6h 44m | 7h 09m |
| Private jet (Gulfstream) | 850 km/h | 7h 07m | 7h 32m |
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 London to Attock?
A non-stop flight from London (LHR) to Attock (ISB) takes about 7h 56m. The great-circle distance is 6,053 km (3,761 miles, 3,268 nautical miles), flying east on an initial bearing of 79°.
How far is London from Attock?
6,053 kilometres in a straight line over the earth's surface — 3,761 miles or 3,268 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 LHR and ISB?
This page calculates the direct-line time and distance; it does not track airline schedules. At 6,053 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 7h 56m 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.
