Washington to Toronto flight path: IAD to YTZ

Sit on the Right side of the plane for the best views on flights from Washington to Toronto. While the departure favors the left side for Appalachian ridge scenery, the right side's payoff during arrival — Lake Ontario, the Toronto Islands, and the downtown skyline with the CN Tower — is more visually striking and memorable, giving the right side the edge for the full flight.

During takeoff from Washington Dulles International (IAD), sit on the Left side for the best views. Departing IAD on the typical northbound runway, the climb-out puts the folded ridgelines of the Blue Ridge and Allegheny Mountains off the left side, giving passengers a look at classic Appalachian ridge-and-valley terrain over Maryland and Pennsylvania. The right side mostly shows flat Piedmont farmland with little definition. Notable sights include: Blue Ridge Mountains, Catoctin Ridge, Allegheny ridge-and-valley terrain, Potomac River valley.

When landing at City Centre (YTZ), sit on the Right side for the best views. On the approach into YTZ, the aircraft typically turns to land facing west, putting downtown Toronto's skyline and the Toronto Islands directly off the right side as the plane descends over Lake Ontario. This gives a strong final view of the CN Tower, harbor, and city skyline just before touchdown. Notable sights include: CN Tower, downtown Toronto skyline, Toronto Islands, Lake Ontario shoreline.

The flight from Washington Dulles International (IAD) to City Centre (YTZ) takes about 1 hour 40 minutes. The shortest flight path between them is 339 miles (545 km); winds and air traffic control usually add a few percent.

The route crosses central Pennsylvania's Allegheny ridges and the Susquehanna River valley, then passes near the Finger Lakes region of upstate New York before descending over the eastern end of Lake Ontario toward Toronto.
