Sit on the Left side of the plane for the best views on flights from Barcelona to Dublin. The left side wins on both ends: Barcelona's coastline and hills at departure, and the Wicklow Mountains plus Dublin Bay coastal approach at arrival. The mid-flight cruise over the Bay of Biscay and open water is scenically neutral for both sides.

During takeoff from Barcelona (BCN), sit on the Left side for the best views. Departing BCN to the north, the left side offers views of the city skyline, the Mediterranean coastline, and the Serra de Collserola hills before the route turns over Catalonia's interior. The coastline and Barcelona's urban grid are the highlight here. Notable sights include: Barcelona coastline, Collserola hills, Barcelona urban grid, Mediterranean Sea.

When landing at Dublin (DUB), sit on the Left side for the best views. Arrivals into Dublin from the south/southeast often bank over the Irish Sea and the Wicklow Mountains before descending along the coast into Dublin Bay. The left side catches the coastal approach with Dublin Bay, the Poolbeg chimneys, and the city visible on final approach. Notable sights include: Wicklow Mountains, Dublin Bay, Poolbeg twin chimneys, Irish Sea coastline.

The flight from Barcelona (BCN) to Dublin (DUB) takes 2h 45m.

Bay of Biscay, French Atlantic coastline near Bordeaux, and the English Channel's western approaches before crossing into Irish airspace
