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 | 12h 56m | 13h 21m |
| Narrowbody jet (A320, 737) | 780 km/h | 9h 07m | 9h 32m |
| Widebody jet (777, 787, A350) | 900 km/h | 7h 54m | 8h 19m |
| Private jet (Gulfstream) | 850 km/h | 8h 22m | 8h 47m |
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 Miami to London?
A non-stop flight from Miami (MIA) to London (LHR) takes about 9h 15m. The great-circle distance is 7,109 km (4,417 miles, 3,838 nautical miles), flying north-east on an initial bearing of 43°.
How far is Miami from London?
7,109 kilometres in a straight line over the earth's surface — 4,417 miles or 3,838 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 MIA and LHR?
This page calculates the direct-line time and distance; it does not track airline schedules. At 7,109 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 9h 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.
