Sit on the Right side of the plane for the best views on flights from Atlanta to Seattle. While the left side (Atlanta departure) offers good urban and Piedmont scenery, the right side (Seattle approach) scores higher due to the dramatic Cascade Range, Mount Rainier's iconic volcanic presence, and Puget Sound's distinctive geography. The landing sequence into Seattle provides significantly more terrain variety and recognizable landmarks than the relatively flat westbound cruise segment. The approach alone elevates the right side's overall score.

During takeoff from DeKalb Peachtree Airport (PDK), sit on the Left side for the best views. Left side captures Atlanta's urban sprawl and the Piedmont terrain during climb-out. The city skyline, surrounding lakes (Lake Lanier to the north), and rolling Appalachian foothills provide immediate visual interest. Right side faces westward over relatively flat terrain with fewer distinctive features during departure. Notable sights include: Atlanta downtown skyline, Lake Lanier (north of PDK), Piedmont plateau terrain, Chattahoochee River valley.

When landing at Seattle Tacoma International (SEA), sit on the Right side for the best views. Right side (north) provides superior approach scenery into Seattle-Tacoma. Descending aircraft typically approach from the east over the Cascade Range foothills, then cross Puget Sound with views of the Olympic Mountains to the west and Mount Rainier to the southeast. Left side faces south over relatively flat terrain and suburban areas with less dramatic features. Notable sights include: Mount Rainier (southeast, snow-capped), Cascade Range foothills, Puget Sound, Olympic Mountains (western horizon).

The flight from DeKalb Peachtree Airport (PDK) to Seattle Tacoma International (SEA) takes 4h 45m.
