Dallas-Fort Worth to Seattle flight path: DFW to SEA

Sit on the Left side of the plane for the best views on flights from Dallas-Fort Worth to Seattle. The left side wins on both ends: a slightly better departure view of the Metroplex and Red River, and a much stronger arrival showing Puget Sound, the Olympic Mountains, and possibly Rainier. The right side spends most of the flight over featureless plains and eventually Idaho's forested but repetitive terrain.

During takeoff from Dallas Fort Worth International (DFW), sit on the Left side for the best views. Departing DFW heading north then curving northwest, the left side offers views back over the Dallas-Fort Worth urban sprawl and eventually the Red River valley separating Texas from Oklahoma. It's a modest start but sets up better plains and terrain visibility as the route continues. Notable sights include: Dallas-Fort Worth Metroplex, Lake Texoma, Red River valley.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. On approach into SEA from the south, the left side reveals Puget Sound with its islands and ferry routes, plus the Olympic Mountains rising across the water to the west. The Seattle skyline and Mount Rainier can also appear briefly during the descent turn. Notable sights include: Puget Sound, Olympic Mountains, Mount Rainier, Seattle skyline.

The flight from Dallas Fort Worth International (DFW) to Seattle Tacoma International (SEA) takes 3h 40m.

Southern Great Plains of Oklahoma and Kansas, the Rocky Mountain foothills near Colorado/Wyoming border, and the Snake River Plain of southern Idaho before crossing into eastern Washington's Columbia Plateau.
