Sit on the Left side of the plane for the best views on flights from Taipei to Seattle. While takeoff favors the right for Taiwan views, the landing experience over Puget Sound, Lake Washington, and the Cascade Range from the left side is more dramatic and visually rewarding. The left side captures the approach corridor's most distinctive geography.

During takeoff from Sungshan (TSA), sit on the Right side for the best views. Sungshan typically departs runway 10 (northwesterly heading). Right-side seats face toward the Taiwan Strait and northern Taiwan's coastline during initial climb, offering immediate views of the strait and the Yangmingshan volcanic plateau to the northwest. Notable sights include: Taiwan Strait (immediate water body below), Yangmingshan volcanic plateau (northwest, distinctive dark ridgeline), Taipei basin urban sprawl (south and southeast), Keelung harbor and northern coast (northeast, visible as industrial waterfront).

When landing at Boeing Fld King Co International (BFI), sit on the Left side for the best views. BFI approaches from the east over Puget Sound. Left-side seats during descent offer views of the Cascade Range to the east, Mount Rainier (when visible), and the approach path over Lake Washington and Elliott Bay. Right seats would face the Olympic Mountains and Bremerton area, which are less dramatic on approach. Notable sights include: Mount Rainier (southeast, snow-capped peak on clear days), Cascade Range (eastern horizon, jagged ridgeline), Lake Washington (directly below during approach, large freshwater body), Elliott Bay and Seattle waterfront (west, industrial piers and downtown skyline).

The flight from Sungshan (TSA) to Boeing Fld King Co International (BFI) takes Approximately 11-12 hours.

The flight crosses the Pacific Ocean for roughly 9-10 hours with no significant landmarks visible—continuous ocean. The Aleutian Islands (Alaska) may be visible on the northern route corridor as small, dark volcanic islands on the horizon if flying at optimal altitude and conditions. The transition to North American airspace occurs over the Gulf of Alaska. The final 2-3 hours approach the Pacific Northwest coast, with the Olympic Mountains and Cascade Range becoming visible 150+ miles before landing, and Mount Rainier appearing as a distinctive white peak approximately 1 hour before touchdown.
