Sit on the Left side of the plane for the best views on flights from Toronto to Dublin. Left side wins at both ends of the flight. Over the Atlantic the views are largely ocean regardless of side, but the left seat delivers the Toronto skyline on departure and Dublin Bay on arrival — the two most visually rewarding moments of the route.

During takeoff from Lester B Pearson International (YYZ), sit on the Left side for the best views. Departing YYZ typically uses runways 05/06L/06R heading northeast, or 23/24L/24R heading southwest. On the dominant northeast departures, the left (north) side gives you a clear view over downtown Toronto, the CN Tower, and Lake Ontario's northern shoreline. On southwest departures, the left side still captures the city core and the lake as you bank. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario stretching south, Toronto Islands and Billy Bishop Airport, Scarborough Bluffs along the lakeshore.

When landing at Dublin (DUB), sit on the Left side for the best views. Flights from Toronto typically approach Dublin from the west, often landing on runway 28L/28R heading westward, meaning the aircraft arrives over the Irish Sea from the east. On a westbound approach, the left (south) side gives views over Dublin Bay, the Poolbeg chimneys, and the city center before touchdown. If landing on runway 10 heading east, the right side would be better, but runway 28 is the dominant arrival direction. Notable sights include: Dublin Bay and the Irish Sea coastline, Poolbeg Generating Station twin red-and-white chimneys, Dublin city center and the River Liffey, Howth Head peninsula to the north.

The flight from Lester B Pearson International (YYZ) to Dublin (DUB) takes Approximately 7 hours 30 minutes to 8 hours.

The flight tracks northeast over Lake Ontario, then over southern Quebec and the Gulf of St. Lawrence, before crossing Newfoundland near St. John's. The route then crosses the North Atlantic, passing south of Greenland and Iceland. Depending on the jet stream routing, you may see the southern tip of Greenland's ice sheet distantly to the north. The Irish coast — County Clare or Connemara's rocky Atlantic shoreline — is typically the first landfall before crossing central Ireland to Dublin.
