What you’ll see on this flight
The right side wins for views, but it is also the sunny side on most departures. If you want the better scenery, take the right and expect some glare. If you want the easier light, the left is the shaded side.
Sit on the right for the best views. That is also the sunny side, so you trade scenery for glare on most departures. If you fly in the evening, the light shifts left and the right side gets easier.
Takeoff
On climbout, Boston is nearly under you on the left, depending on the runway in use. Then Massachusetts Bay slips by on the right, also near the aircraft for a moment.
En route
- 40m inRight →Bay of Fundy · passes underneath
About 40 minutes in, the Bay of Fundy is almost beneath the right side. It is a quick, steep look, not a long linger.
- 1h 10m inRight →Cape Breton Island
Around 70 minutes in, Cape Breton Island sits out on the right. You get a clear island view before it slides back.
- 1h 43m inRight →Newfoundland
Just after that, Newfoundland stays on the right. It reads as a broad landmass, not a tiny speck.
- 5h 52m inRight →Croagh Patrick · passes underneath
A couple of minutes later, Croagh Patrick is nearly under the right side. It is brief, steep, and close.
- 5h 54m inRight →Cliffs of Moher
On descent, the Cliffs of Moher come up on the right. You see the Atlantic edge, then the land tightens in toward approach.
Landing
On approach to Dublin, the Wicklow Mountains are on the right, depending on the runway in use. Dublin itself is nearly under the right side at landing.
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 BOS to DUB?
Across typical daytime departures, the sun predominantly hits the right side of the aircraft, so the left side stays shadier. Seat letters start at the left window, so choose an A seat.
Which side has the sunset views on BOS 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 BOS to DUB?
The great-circle distance is 4,804 km (2,985 mi), which works out to roughly 6h 9m in the air on this eastbound 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 of the plane has the best views from BOS to DUB?
The right side. That is where the stronger route views are, especially over the Atlantic crossing and on approach into Ireland.
Which side is shaded on this BOS to DUB flight?
The left side. On typical departures, the sun is on the right, so the left gets the shade.
