Sydney to Seattle flight path: SYD to SEA

Sit on the Left side of the plane for the best views on flights from Sydney to Seattle. The left side captures Sydney's harbour and skyline on departure and Mount Rainier with the Cascades on arrival, giving it the edge over the right side's Botany Bay takeoff and Puget Sound/Olympics landing, though both sides are dominated by roughly thirteen hours of open Pacific Ocean in between.

During takeoff from Kingsford Smith International Airport (SYD), sit on the Left side for the best views. Departing Sydney to the north, the right-turn out over the Tasman brings Sydney Harbour, the Harbour Bridge, and the CBD skyline into view on the left side before the aircraft settles onto its oceanic track. The right side only shows Botany Bay and the Cronulla coastline before open water. Notable sights include: Sydney Harbour Bridge, Sydney Opera House, CBD skyline, Northern Beaches coastline.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. On the typical southbound approach into Seattle, the left side faces east toward the Cascade foothills, Lake Washington, and the snow-capped cone of Mount Rainier rising on the horizon. The right side mainly sees Puget Sound and the Olympic Mountains, which are scenic but less distinctive than Rainier's silhouette. Notable sights include: Mount Rainier, Cascade Range foothills, Lake Washington, Interstate 90 floating bridge.

The flight from Kingsford Smith International Airport (SYD) to Seattle Tacoma International (SEA) takes about 13 hours 35 minutes. The shortest flight path between them is 7,750 miles (12,472 km); winds and air traffic control usually add a few percent.

The route crosses the vast central Pacific Ocean with no land visible for many hours, passing well east of New Caledonia and Fiji before curving north past the Hawaiian latitudes and eventually approaching the North American coast near Vancouver Island and British Columbia.
