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 15m | 20h 40m |
| Narrowbody jet (A320, 737) | 780 km/h | 14h 17m | 14h 42m |
| Widebody jet (777, 787, A350) | 900 km/h | 12h 22m | 12h 48m |

Questions
How long is the flight from London to Buenos Aires (Ezeiza)?
A non-stop flight from London (LHR) to Buenos Aires (Ezeiza) (EZE) takes about 14h 15m. The great-circle distance is 11,137 km (6,920 miles, 6,013 nautical miles), flying south-west on an initial bearing of 225°.
How far is London from Buenos Aires (Ezeiza)?
11,137 kilometres in a straight line over the earth's surface — 6,920 miles or 6,013 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 EZE?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,137 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 15m 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.
