Sit on the Left side of the plane for the best views on flights from Singapore to Seattle. Left side wins both the departure from Singapore and the arrival into Seattle, making it the clear choice for the full journey. The departure captures Singapore's iconic skyline and the Strait of Johor, while the arrival delivers the Seattle CBD, Elliott Bay, and a distant Mount Rainier on the same side.

During takeoff from Singapore Changi (SIN), sit on the Left side for the best views. Changi typically departs on runway 02L/02R heading north, or 20L/20R heading south. On a northbound departure toward the Pacific, a left-side seat gives you views over the Strait of Johor, peninsular Malaysia's coastline, and the dense urban grid of Singapore city center as the aircraft banks right toward its routing. The southern city skyline including Marina Bay and the CBD is clearly visible on the left during the initial climb. Notable sights include: Marina Bay Sands and CBD skyline, Strait of Johor, Johor Bahru across the causeway, Sentosa Island.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. SeaTac typically lands on runways 16L/16R heading south, meaning the approach comes in from the north over the Seattle metro area. A left-side seat on this southbound approach gives a direct view of downtown Seattle, Elliott Bay, and Mount Rainier to the southeast. The Olympic Mountains across Puget Sound are also visible to the right but the left side captures the city and the iconic mountain backdrop together. Notable sights include: Downtown Seattle skyline, Elliott Bay and Puget Sound, Mount Rainier, Lake Washington.

The flight from Singapore Changi (SIN) to Seattle Tacoma International (SEA) takes Approximately 16 to 17 hours nonstop.

The great circle route from Singapore to Seattle tracks northeast over the South China Sea, crosses the Philippines archipelago, then arcs across the vast North Pacific Ocean passing south of Japan and the Aleutian Island chain. The flight crosses the International Date Line roughly midway. Over the North Pacific there are few landmarks, but on clear days the volcanic peaks of the Aleutian Islands such as Shishaldin or Pavlof may be faintly visible as snow-capped cones near the horizon. The final approach crosses the British Columbia coast and the Cascade Range before descending into the Puget Sound basin.
