Flight time & jet lag: Reykjavik to London

Reykjavik to London: Route overview

This medium-haul European route links Reykjavik with London over 1,895 km, offering a quick 2h 44m to 3h 16m connection within the same time zone. Since Reykjavik and London share effectively the same UTC offset, jet lag is not a factor, though the travel time itself can cause fatigue. The route passes through Europe's airspace, with flight paths that may vary by season due to weather patterns along the corridor.

What makes the Reykjavik–London route different

This route is unusual in that it covers a substantial distance (1,895 km) without crossing time zones. The main challenge is travel fatigue from the medium-haul flight rather than circadian disruption, making recovery straightforward — usually within 24 hours.

Arrival strategy for London

Arriving in London without a time zone change means your body clock is aligned with the local schedule. Focus on staying hydrated during the flight, eating a meal on arrival at a local mealtime, and getting moderate physical activity to counter travel fatigue. Most people feel fully recovered after one good night's sleep.

Seasonal and climate factors

Flight times between Reykjavik and London can vary by 15–30 minutes seasonally due to shifting wind patterns along this medium-haul corridor. London at 51°N experiences moderate seasonal daylight variation. Summer offers longer evenings useful for westward adjustment, while winter's earlier sunsets support eastward adjustment schedules.

How the Reykjavik–London flight time is estimated

The 2h 44m to 3h 16m estimate for Reykjavik to London is derived from the 1,895-km great-circle distance. Medium-haul flights balance cruise and non-cruise phases, achieving effective speeds of 780–850 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both KEF and LHR. Actual routing through controlled airspace may add 3–8% distance beyond the great-circle path due to air traffic corridors and restricted zones along the way.

Wind patterns and flight duration

Prevailing winds along the Reykjavik–London corridor have a moderate effect on flight time. With minimal east-west component, this route is less affected by the jet stream than transatlantic or transpacific routes.
