Sit on the Right side of the plane for the best views on flights from Detroit to Washington. The right side wins overall because the takeoff views over the Detroit River, Lake Erie, and the Ohio landscape are more visually dramatic and geographically interesting than the landing views from the left. The right side also tracks the Appalachian foothills and Pennsylvania farmland through the cruise portion of the flight, offering consistent scenery. The left-side landing view of the Blue Ridge is good but the mountains are distant and low from that approach angle.

During takeoff from Detroit Metro Wayne Co (DTW), sit on the Right side for the best views. DTW's primary departure runways (21L/21R heading southwest, or 04L/04R heading northeast) mean a right-side seat gives you views over the Detroit River and Lake Erie to the south. You'll see the Detroit metropolitan grid, the river separating the US and Canada, and the western edge of Lake Erie as you climb out heading southeast toward IAD. Notable sights include: Detroit River (US-Canada border), western Lake Erie shoreline, Toledo metro area to the south, Detroit city grid and downtown skyline.

When landing at Washington Dulles International (IAD), sit on the Left side for the best views. IAD's primary arrival runways (01C/01L heading north, or 19C/19R heading south) on approaches from the north put the left side facing west toward the Blue Ridge Mountains and the Shenandoah Valley. On a standard approach from the northwest, the left seat also picks up the Potomac River and the broader DC metro area as you descend. Notable sights include: Blue Ridge Mountains and Shenandoah Valley to the west, Potomac River, Dulles Access Road corridor, Tysons Corner urban cluster.

The flight from Detroit Metro Wayne Co (DTW) to Washington Dulles International (IAD) takes Approximately 1 hour 20 minutes to 1 hour 35 minutes.

The flight path crosses northwestern Ohio's flat agricultural grid, then moves over central and eastern Ohio before entering Pennsylvania. Over Pennsylvania you'll see the folded ridge-and-valley Appalachians — the parallel ridges of the Ridge and Valley province are distinctly visible from altitude as long dark forested lines running northeast to southwest. The Allegheny Front is the most prominent single ridge. Crossing into Maryland and West Virginia, the terrain becomes more dissected before flattening into the Piedmont approaching Dulles.
