Sit on the Left side of the plane for the best views on flights from Philadelphia to Dublin. While takeoff favors the right, landing offers more dramatic and sustained views. The approach into Dublin Bay and the Irish coastline provides superior geography compared to the industrial Delaware River departure. Left seats capture the entire Irish Sea crossing finale and Dublin's distinctive bay geography.

During takeoff from Philadelphia International (PHL), sit on the Right side for the best views. PHL typically departs eastbound (Runways 09L/09R) over the Delaware River and New Jersey. Right-side seats capture the river's industrial corridor, the city skyline receding westward, and the Pine Barrens extending southeast into New Jersey. Notable sights include: Delaware River (immediate right, running north-south), Philadelphia skyline (left-center, receding), New Jersey Pine Barrens (right, extending to horizon), Atlantic City area (far right on clear days).

When landing at Dublin (DUB), sit on the Left side for the best views. Dublin approaches typically use Runways 10/28 depending on wind. For eastbound arrivals (common from North America), left-side seats on descent into Runway 10 offer views of the Irish Sea, Dublin Bay's distinctive curved shoreline, and the city's north-side approach corridor including the Liffey estuary. Notable sights include: Irish Sea (left, extending to horizon), Dublin Bay (left-center, curved shoreline), Liffey River estuary (center, visible as a thin line through city), Wicklow Mountains (right-rear, distant blue ridge).

The flight from Philadelphia International (PHL) to Dublin (DUB) takes Approximately 6.5 to 7 hours.

The flight crosses the Atlantic at roughly 35,000 feet where no landmarks are visible—only open ocean. However, the route passes north of Newfoundland (not visible at cruise altitude) and approaches Ireland from the west over the Atlantic. On descent into Dublin, the Irish coastline becomes visible around 10,000 feet, with the Wicklow Mountains and Dublin Bay geography becoming prominent below 5,000 feet.
