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 | 14h 21m | 14h 46m |
| Narrowbody jet (A320, 737) | 780 km/h | 10h 07m | 10h 32m |
| Widebody jet (777, 787, A350) | 900 km/h | 8h 46m | 9h 11m |
| Private jet (Gulfstream) | 850 km/h | 9h 17m | 9h 42m |
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 Austin?
A non-stop flight from London (LHR) to Austin (AUS) takes about 10h 13m. The great-circle distance is 7,892 km (4,904 miles, 4,261 nautical miles), flying north-west on an initial bearing of 295°.
How far is London from Austin?
7,892 kilometres in a straight line over the earth's surface — 4,904 miles or 4,261 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 AUS?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,892 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 10h 13m 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.
