Flight time from London to Dublin

How long is the flight from London to Dublin?

Counting only time in the air, London to Dublin is about 1h 11m non-stop. That figure comes from the 463-kilometre great-circle distance, the shortest line over the curve of the Earth, stretched by a small margin for real routing and divided by typical jet cruise speed, with taxi, climb, and descent folded in. On a real schedule the block time can run longer or shorter: headwinds, air-traffic routing, and the specific aircraft all move the number. The westbound leg of a long route into prevailing winds is often the slower of the two directions.

Time difference between London and Dublin

London and Dublin sit in the same time zone, so the clock does not jump when you land. The duration the boarding pass implies is the real one, no hidden offset to unwind. That makes this an easy route for the body clock.

Jet lag on this route

With no time-zone change, this route should not produce meaningful jet lag, any tiredness is from the flight itself, not a misaligned body clock. Hydrate, move around the cabin, and you should feel normal on arrival.

Distance and the great-circle path

The 463 km figure is the great-circle distance, computed with the haversine formula between the two city coordinates. On a flat map it can look like a curve, because the shortest real-world path bows toward the pole rather than following a straight line of latitude, which is why London-Dublin flights often track far north or south of where the map suggests. Real flown distance is a touch longer, around 491 km here, once airways and weather routing are added. To unwind the time-zone math on your own specific flight, enter the boarding-pass times below.
