London, United Kingdom to Addis Ababa, Ethiopia crosses 2 time zones — and you’re going east, the harder direction. Addis Ababa is 2 hours ahead of home, on a flight of about 7 hours.
Your body resists going to sleep earlier far more than going to sleep later. That’s why eastbound trips like this one chew up more days than the same number of zones in the other direction — your circadian clock has to be pulled forward, against its natural drift.
For most travelers, that translates to about 2 days of feeling off. We grade this route as easy. The plan below is built around the things that actually move your body clock — light, sleep timing, caffeine, and (if you want it) a small dose of melatonin — applied at the times when they actually work.
How to fly London → Addis Ababa without losing the first three days.
- 1Three days before — start sleeping a little earlier
Move bedtime 40 minutes earlier each night for the three nights before you fly, and wake the same amount earlier. Get bright light within 30 minutes of waking. Skip evening light — sunglasses if you’re out late.
- 2On the plane — sleep when the destination sleeps
If you arrive in the morning, get four solid hours on board, aligned with night at the destination. Eye mask, no alcohol, water every hour. If you arrive in the evening, do the opposite — stay awake.
- 3Day one — sunlight in the morning, no big nap
Step outside within thirty minutes of waking. A short nap is fine before 14:00 if you’re wrecked, but keep it under thirty minutes. Eat on local meal times — meals are a circadian cue almost as strong as light.
- 4Optional — 0.5 mg melatonin half an hour before bed
Low-dose melatonin (0.5–1 mg) is the dose backed by research; high-dose pills are not better. Use it for the first three to five nights only. Talk to a doctor first if you take medication or are pregnant.
- 5Cut caffeine eight hours before bed
Caffeine has a half-life of about five hours; eight hours before bed clears most of it. If you’re sensitive, give yourself twelve. Strategic morning coffee is fine and helps you stay awake during the destination day.
More about flying London to Addis Ababa
Flight basics: London → Addis Ababa
Flights are 7–8 hours, mostly nonstop via Ethiopian Airlines, or one connection through Middle Eastern hubs. Direct flights leave London afternoon and arrive Addis evening. The altitude (7,700 feet) adds mild adjustment pressure.
When to go (and when to brace)
October–December is optimal: Addis Ababa's cool dry season (15–22°C daytime) is comfortable, London's autumn is mild. April–May rains and June–August chills are less ideal.
At London
Fly Ethiopian if possible—they know the route and Addis well. Depart mid-afternoon from London, nap 2 hours on board, arrive evening ready for local dinner and evening acclimation.
After landing in Addis Ababa
Walk Meskel Square for 1 hour at evening. Eat traditional injera at a local restaurant. Return to hotel by 10 pm Addis time. Sleep. The altitude takes a day to adjust to, but jet lag itself is mild.
What to actually expect
Addis surprised me—the 7-hour flight was short enough that I wasn't wrecked, and the altitude was noticeable (headache first day) but worse than jet lag. A walk, food, and one good sleep fixed everything. By day 2 I felt normal.

Frequently asked
How many hours is the time difference between London and Addis Ababa?+
Addis Ababa is 2 hours ahead of London. The exact gap can shift by an hour twice a year if either city observes daylight saving time.
How bad is the jet lag from London to Addis Ababa?+
You’re flying east, crossing 2 time zones. Most people need about 2 days to feel normal. The first 48 hours are the worst — that’s when sleep is the most fragmented and the afternoon energy crash is the deepest.
Should I take melatonin?+
For eastbound trips of this size, a low dose (0.5–1 mg) thirty minutes before your destination bedtime can shave a day or two off recovery. Use it for the first three to five nights, not indefinitely. Talk to a clinician first if you take other medication or are pregnant.
When is the best time to take a nap on arrival?+
Before 14:00 local time, no longer than 30 minutes. Naps later than that bleed into the evening and push your bedtime even further back, which is the opposite of what you want.
Does staying hydrated really help?+
Cabin air is 10–20% humidity (drier than the Sahara). Dehydration mimics the symptoms of jet lag — headache, fatigue, brain fog — so a hydrated traveler is just less miserable, even if their underlying clock hasn’t shifted yet. Alcohol multiplies the effect; skip it on the flight.
