Sit on the Left side of the plane for the best views on flights from Seattle to Oklahoma City. The left side delivers the most dramatic scenery of the entire flight. The Cascade Range and Mount Rainier on departure are genuinely spectacular, and as the flight tracks southeast, the left side also captures the Columbia Plateau, the Blue Mountains of Oregon, and later the Snake River Plain. The right side has a slight edge only on landing approach into OKC.

During takeoff from Seattle Tacoma International (SEA), sit on the Left side for the best views. SEA primarily uses runways 16L/16R for southbound departures, meaning a left-side seat faces east toward the Cascade Range. You get a clear view of Mount Rainier dominating the skyline, with the Seattle city skyline and Elliott Bay visible during the initial climb before the aircraft turns southeast. Notable sights include: Mount Rainier (14,411 ft), Elliott Bay and downtown Seattle skyline, Lake Washington, Cascade Range foothills.

When landing at Will Rogers World (OKC), sit on the Right side for the best views. Will Rogers World Airport primarily uses runway 17R/35L, with arrivals from the north typically landing on runway 17R heading south. A right-side seat on approach from the north faces west, giving you a view over Oklahoma City's downtown skyline, the Oklahoma River, and the flat red-dirt plains of central Oklahoma spreading to the horizon. Notable sights include: Oklahoma City downtown skyline, Oklahoma River (North Canadian River), Lake Hefner, flat red-clay plains of central Oklahoma.

The flight from Seattle Tacoma International (SEA) to Will Rogers World (OKC) takes Approximately 3 hours 15 minutes to 3 hours 45 minutes.

After departing Seattle, the route crosses the Cascade Range and the Columbia Plateau of eastern Washington, then tracks over the Blue Mountains of northeastern Oregon. The flight passes over the Snake River Plain in southern Idaho, then crosses the high desert of Utah and Colorado's western slope. Over Colorado and Kansas, the terrain flattens dramatically into the Great Plains, with the Arkansas River valley visible in southern Kansas before descending into the red-clay flatlands of central Oklahoma.
