Sit on the Left side of the plane for the best views on flights from Hong Kong to Seattle. The left side wins both takeoff and landing — Hong Kong's harbor skyline at departure and Puget Sound with the Olympic Mountains and Seattle skyline at arrival — while the cruise portion over the North Pacific is scenically neutral for both sides.

During takeoff from Hong Kong International (HKG), sit on the Left side for the best views. Departing HKG northbound, the left side offers views back over Hong Kong Island's skyline, the harbor, and the surrounding green hills of the New Territories before the route heads out over the Pearl River Delta. It's a dense, dramatic urban-coastal departure. Notable sights include: Hong Kong Island skyline, Victoria Harbour, Lantau Island, Pearl River Delta.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. On approach into SEA from the north, the left side typically offers views of the Olympic Mountains and Puget Sound, plus a chance to see Seattle's downtown skyline and the waterfront as the plane descends. The right side mostly faces the flatter Cascades foothills and suburban terrain. Notable sights include: Puget Sound, Olympic Mountains, Seattle skyline, Elliott Bay.

The flight from Hong Kong International (HKG) to Seattle Tacoma International (SEA) takes 10h 30m.

North Pacific Ocean, possible distant views of the Kamchatka Peninsula or Aleutian Islands depending on routing, otherwise open water for several hours
