Flight time & jet lag: Dubai to London

Dubai to London: Route overview

This long-haul route from Dubai (DXB) to London (LHR) covers 5,497 km in approximately 6h 36m to 7h 32m, crossing 4 time zones westbound. The 4-hour westbound shift means your body clock will be noticeably out of sync for 2–3 days, affecting sleep quality, appetite, and concentration at your destination. The route transitions between subtropical and temperate climate zones, so expect a significant change in daylight duration and intensity that influences your circadian adjustment strategy.

What makes the Dubai–London route different

The specific combination of 5,497 km distance, 4-hour time difference, and westbound direction places this route in the moderate jet lag category. Compared to a same-distance route with fewer time zones crossed, the circadian challenge here is the dominant factor in post-arrival recovery.

Arrival strategy for London

Flying west to London gains you 4 hours, extending your arrival day. At 18:00 local time, your body will think it is 22:00 — meaning you will feel ready for sleep well before the local bedtime. Counter this by getting bright light in the late afternoon and early evening. Eat dinner at the local time, stay physically active, and push your bedtime to at least 21:00 local. Avoid morning light before 08:00 on the first few days, as this would advance your clock in the wrong direction.

Circadian rhythm analysis: Dubai → London

When you arrive in London, your circadian rhythm is still running on Dubai time. At 09:00 London time, your body reads 13:00 — your body's mid-afternoon, meaning you will be alert and functional during the local morning. The main westbound challenge is that by 22:00 local, your body clock reads 02:00 — the deep night on your internal clock. You will feel intensely sleepy well before the local bedtime. Your circadian system adjusts at roughly 1 to 1.5 hours per day, so expect 3 days for full alignment.

Pre-departure preparation

For this 4-hour westward shift to London, start 4 days before departure by delaying your bedtime by 60 minutes each night. Seek bright light in the evening hours to help push your clock later. On the flight, try to stay awake if arriving during London's daytime. This gradual shift can significantly ease your transition upon arrival.

Your first 72 hours in London

Day 1 in London: Your body is ~4 hours off local time. Stay active and seek afternoon sunlight. Push bedtime to at least 21:00 local. Eat at local mealtimes even if not hungry. Caffeine is fine before 16:00, not after. Day 2: ~3 hours off. Continue late afternoon (15:00–18:00) light exposure. Sleep quality should improve. Day 3: ~1 hours off. You should feel mostly adjusted. Return to normal activities.

Recovery timeline

Full circadian adjustment for the Dubai → London route typically takes 3 days, based on the body's natural adaptation rate of ~1 to 1.5 hours per day for westbound travel. During this period, expect gradually improving sleep quality, with the most noticeable symptoms (fatigue, difficulty concentrating, appetite changes) during the first 3 days. By day 3, most travelers report feeling fully synchronized with London's schedule.

Seasonal and climate factors

Flight times between Dubai and London can vary by 15–30 minutes seasonally due to shifting wind patterns along this long-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 Dubai–London flight time is estimated

The 6h 36m to 7h 32m estimate for Dubai to London is derived from the 5,497-km great-circle distance. Long-haul flights spend most of their duration at optimal cruise altitude (typically 35,000–40,000 feet), achieving effective speeds of 820–900 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both DXB 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 Dubai–London corridor have a moderate effect on flight time. Westbound flights may encounter mild headwinds from the general west-to-east upper atmospheric flow.

Practical travel context

This long-haul route connects Dubai (United Arab Emirates) with London (United Kingdom). Most travelers on stays of 3 days or longer will benefit from fully adjusting to London's local time, as the 4-hour shift is manageable within the first 2–3 days with proper light and sleep management.
