Sit on the Right side of the plane for the best views on flights from Lisbon to Dublin. While takeoff favors the left for Lisbon's estuary views, the landing approach into Dublin from the south/southeast provides more dramatic geography—Dublin Bay, the Wicklow Mountains, and the city's coastal setting are more visually distinctive than the departure views. Right seats capture the better overall experience for this route.

The flight path crosses the Celtic Sea, passing west of Wales and southwest of the Pembrokeshire coast. At cruise altitude (around 30,000 feet), you'll be too high to see fine detail, but the Irish Sea's general geography becomes apparent on descent into Dublin. The Welsh coastline and Snowdonia mountains are visible to the east (right) during the northern portion of the flight, though they remain distant. The flight primarily crosses open water with no major landmarks visible at cruise altitude.
