Sit on the Right side of the plane for the best views on flights from Denver to Dublin. While the left offers excellent Rocky Mountain views at takeoff, the right side wins overall because the Dublin approach provides more sustained scenic interest—coastline, bay, mountains, and city views all converge during descent. The transatlantic crossing itself offers little visual interest (open ocean for 6+ hours), making the destination views the deciding factor.

During takeoff from Denver International (DEN), sit on the Left side for the best views. Left-side seats offer the best views during Denver departure. You'll see the Front Range of the Rocky Mountains immediately west of the airport, with the Continental Divide visible on clear days. The city of Denver itself spreads out to the southeast as you climb. Notable sights include: Front Range (Rocky Mountains), Continental Divide, Denver metropolitan area, South Platte River valley.

When landing at Dublin (DUB), sit on the Right side for the best views. Right-side seats provide excellent views during the Dublin approach. You'll see the Irish coastline, Dublin Bay, and the city itself as you descend into the final approach corridor from the east. The Wicklow Mountains are visible to the south on clear days. Notable sights include: Dublin Bay, Irish coastline (Dublin and Dún Laoghaire), Wicklow Mountains, River Liffey estuary.

The flight from Denver International (DEN) to Dublin (DUB) takes Approximately 9.5 to 10.5 hours.

The flight path crosses the Great Plains (flat, minimal visual interest), then over the Atlantic Ocean for the majority of the journey. Approximately 4-5 hours into the flight, you'll pass over or near Newfoundland and the Canadian Maritime provinces if taking a northern routing. The final 2-3 hours approach the Irish and British Isles, with potential views of the Scottish Highlands, Lake District, or Welsh mountains depending on exact approach routing. The approach into Dublin typically comes from the east over the Irish Sea, providing coastal views of Ireland's eastern seaboard.
