Sit on the Right side of the plane for the best views on flights from Seattle to Dublin. While the takeoff offers dramatic mountain views from the left, the landing approach on the right provides more sustained scenic interest with coastal geography, a major bay system, and mountain ranges. The right side captures the transition from ocean to urban landscape, which is more visually engaging overall.

During takeoff from Boeing Fld King Co International (BFI), sit on the Left side for the best views.

Notable sights include: Dublin Bay, Wicklow Mountains, Irish coastline, River Liffey estuary.

The flight from Boeing Fld King Co International (BFI) to Dublin (DUB) takes 9h 15m.

The flight path crosses the North Atlantic, passing over or near Newfoundland and Labrador, then over the Atlantic Ocean proper. Notable features include the Canadian Maritime provinces (visible during early stages), the vast Atlantic expanse with occasional cloud formations, and the approach to the Irish coast with the Atlantic meeting the European landmass. The Greenland ice sheet may be visible on clear days during the northern portion of the route, though it depends on exact routing.
