Sit on the Right side of the plane for the best views on flights from Washington to Vancouver. While the westbound climb offers Appalachian views on the left, the approach into Vancouver on the right provides more dramatic and distinctive scenery—the North Shore Mountains are far more visually striking than the eastern ranges, and the coastal geography of the Strait of Georgia and Vancouver's urban setting against mountains is the flight's scenic highlight.

During takeoff from Washington Dulles International (IAD), sit on the Left side for the best views. Left seats offer views of the Appalachian Mountains as the aircraft climbs westward out of IAD. The ridgelines become visible within 15–20 minutes of departure, stretching across the horizon in a series of parallel ridges running northeast to southwest. Notable sights include: Appalachian Mountains (Blue Ridge and Allegheny ranges), Shenandoah Valley, Potomac River valley, Washington D.C. metropolitan area receding eastward.

When landing at Vancouver International (YVR), sit on the Right side for the best views. Right seats provide the best views during descent into YVR. As the aircraft approaches from the southeast, right-side passengers see the North Shore Mountains (part of the Coast Range) rising dramatically above the city, followed by views of the Strait of Georgia and Vancouver's urban layout spreading across the Lower Mainland. Notable sights include: North Shore Mountains (Grouse, Seymour, Cypress peaks), Strait of Georgia, Vancouver city grid and False Creek, Fraser River delta.

The flight from Washington Dulles International (IAD) to Vancouver International (YVR) takes 5h 15m.

Great Lakes region (Lake Michigan, Lake Huron visible from altitude), transition from Appalachian terrain to Great Plains, Canadian Shield forests in Ontario and Quebec, Rocky Mountains visible during descent into British Columbia (Canadian Rockies on the eastern horizon approaching the Pacific coast)
