Sit on the Left side of the plane for the best views on flights from Dublin to Chicago. Left side wins both ends of the flight — Dublin Bay and the Irish coast on departure, and the Chicago skyline with Lake Michigan on approach. Over the mid-Atlantic the views are ocean regardless of side, so the departure and arrival scenery is the deciding factor.

During takeoff from Dublin (DUB), sit on the Left side for the best views. Dublin departures on runway 28 (westbound) or 10 (eastbound) both offer the left side a view over Dublin Bay, the Liffey estuary, and the city centre. As the aircraft climbs and turns northwest toward the Atlantic, the left side tracks along the Irish coastline with Howth Head and Dublin Bay clearly visible below. Notable sights include: Dublin Bay and Howth Head, the Liffey estuary and city centre, Wicklow Mountains to the south, Bull Island nature reserve.

When landing at Chicago Ohare International (ORD), sit on the Left side for the best views. Flights from Dublin typically approach O'Hare from the northeast on runway 10 or 28 depending on winds. On the standard northeast approach, the left side gets Lake Michigan's southern shoreline, the Chicago skyline, and the dense urban grid of the North Side. The right side faces suburban sprawl with little of interest. Notable sights include: Lake Michigan southern shoreline, Chicago downtown skyline, North Side urban grid, O'Hare's runway complex.

The flight from Dublin (DUB) to Chicago Ohare International (ORD) takes Approximately 8 to 9 hours westbound.

The flight tracks northwest from Dublin across the Irish Sea, then over Donegal and out across the North Atlantic on a great circle route passing south of Greenland and Iceland. The southern tip of Greenland's ice sheet may be visible on clear days far to the north. The route then crosses Labrador and Quebec in Canada, where the boreal forest and lake-studded Canadian Shield are visible below, before crossing into the Great Lakes region over Lake Huron and Lake Michigan on descent into Chicago.
