LHR to DUB: which side of the plane should you sit on?
London (LHR) to Dublin (DUB) is a 449 km (279 mi), roughly 1h 2m westbound flight. Here is where the sun sits along that path, computed with the same astronomy as our live calculator.
On most daytime LHR to DUB departures the sun favors the left side — sit on the right (a window on the right) for shade.

What you’ll see on this flight
The right side wins here: it gets the better views and the shade.
Sit on the right for this westbound hop. The route lines up with the shady side, and that same side gets the stronger views.
Takeoff
On climbout, the right side looks good from the start. You can catch London, London Bridge, Tower Bridge, and the City of Westminster off that side, depending on the runway in use.
En route
- 20m inRight →Birmingham
About 20 minutes in, Birmingham comes up on the right. It is a clear city pass, with Coventry and Wolverhampton close by on the same side.
- 23m in← LeftCardiff
A few minutes later, Cardiff sits off the left, so it is the counterpoint rather than the main view on this route.
- 25m inRight →Ironbridge Gorge
Near the middle of the flight, Ironbridge Gorge is on the right. It is one of the sharper landscape moments on the route.
- 34m inRight →Great Britain
About half an hour in, Great Britain stays on the right as a broad island outline, not a close-up scene.
- 42m inRight →Snowdon
On descent, Snowdon and the Snowdonia area stay on the right. Snowdon is the highest mountain in Wales, and it passes well off to that side.
Landing
Coming into Dublin, the left side is the one to watch. Wicklow Mountains appear first, then Dublin comes nearly under the aircraft from that side, about a minute before landing, depending on the runway in use.
Sides and timings are computed from this route’s geometry. What you actually see depends on weather, air-traffic routing, and the runway in use on the day.
Frequently asked
Which side of the plane avoids the sun from LHR to DUB?
Across typical daytime departures, the sun predominantly hits the left side of the aircraft, so the right side stays shadier. Seat letters start at the left window, so choose the highest window letter (F on narrowbodies, K on many widebodies).
Which side has the sunset views on LHR to DUB flights?
For sunset views, flip the advice: on evening departures the sun sits on the left side of this route, so that is the side with the show.
How long is the flight from LHR to DUB?
The great-circle distance is 449 km (279 mi), which works out to roughly 1h 2m in the air on this westbound routing. Winds and routing move the real block time around that estimate.
Does the date or departure time change the answer?
Yes — that is why the table shows both. The sun's path shifts with the season, and a morning departure can put the glare on the opposite side compared to an evening one. For a specific flight, the calculator samples the sun along the whole route for your exact date and time.
Which side should I sit on from London Heathrow to Dublin?
Sit on the right. It is the better view side, and it also keeps you on the shade side for this westbound flight.
What can I see on the way to Dublin?
You get London early, then city views around Birmingham and the Midlands, Ironbridge Gorge, Great Britain, and Snowdon before the descent into Dublin.
