Sit on the Right side of the plane for the best views on flights from Seattle to Taichung (Qingshui). While Seattle's departure is scenic, the right side wins overall because the landing approach into Taichung provides sustained dramatic scenery: the Taiwan Strait crossing, the striking contrast between ocean and mountainous terrain, and the Central Mountain Range backdrop create more visual variety and landmark density than the predominantly ocean-based cruise segment. The left side suffers from 10+ hours of open Pacific Ocean with minimal features, whereas the right side benefits from a visually rich approach sequence.

During takeoff from Seattle Tacoma International (SEA), sit on the Left side for the best views. Seattle departure offers immediate Puget Sound views and the Cascade Range to the east. The left side captures the urban waterfront, Elliott Bay, and snow-capped Mount Rainier during climb-out, providing dramatic terrain contrast within the first 15 minutes. Notable sights include: Mount Rainier (14,411 ft, visible southeast), Puget Sound and Elliott Bay (urban water features), Cascade Range foothills, Seattle-Tacoma urban sprawl.

When landing at Taichung International Airport / Ching Chuang Kang Air Base (RMQ), sit on the Right side for the best views. The right side during approach to Taichung captures the Taiwan Strait coastline, the western coastal plain, and the Central Mountain Range backdrop. Descent into Taichung reveals the dramatic transition from ocean to agricultural lowlands and urban development, with the high peaks of Taiwan's interior visible inland. Notable sights include: Taiwan Strait (western approach), Taichung Harbor and coastal industrial zones, Central Mountain Range (Yushan massif visible inland), agricultural plains of central Taiwan.

The flight from Seattle Tacoma International (SEA) to Taichung International Airport / Ching Chuang Kang Air Base (RMQ) takes 11h 15m.

North Pacific Ocean (open water dominates 70% of cruise); Aleutian Islands region passes to the north (not directly visible on typical routing); International Date Line crossing; gradual transition from temperate to subtropical air masses; no significant terrain features visible during mid-cruise; approach to Taiwan begins with Luzon Strait and Philippine Sea, then Taiwan's dramatic east coast (if visible on descent routing) or western coastal approach depending on final approach vector
