Sit on the Left side of the plane for the best views on flights from Taipei to Denver. While takeoff offers brief coastal scenery, the landing approach provides far superior views. The Rocky Mountain Front Range during descent is one of North America's most dramatic aerial sights—towering peaks, visible snow, and the stark contrast between mountains and plains make left-side seats the clear winner for this transpacific route.

During takeoff from Chiang Kai Shek International (TPE), sit on the Right side for the best views. Right-side seats offer views of Taiwan's northeastern coastline and the Pacific Ocean immediately after departure. The aircraft climbs northeastward over the Taiwan Strait, giving right-side passengers clear sightlines to the rugged coastal terrain and offshore islands. Notable sights include: Taiwan's northeastern coast near Keelung, Pacific Ocean, Jiufen and Ruifang mountainous terrain, Keelong Harbor.

When landing at Denver International (DEN), sit on the Left side for the best views. Left-side seats provide excellent views during the descent into Denver. The aircraft approaches from the northeast, and left-side passengers see the Rocky Mountains in their full dramatic profile—the Front Range rises directly ahead and to the left as the plane descends toward the high plains. Notable sights include: Rocky Mountain Front Range (including Mount Evans and the central peaks), South Platte River valley, Denver metropolitan area sprawl, High Plains extending eastward.

The flight from Chiang Kai Shek International (TPE) to Denver International (DEN) takes Approximately 14-15 hours.

The flight crosses the Pacific Ocean for roughly 8-9 hours with minimal visible landmarks—occasional cloud formations and open ocean. As the aircraft approaches the North American continent, the Aleutian Islands may be visible in the far north (depending on exact routing). Crossing into Canadian airspace, the Canadian Rockies and British Columbia's mountain terrain become visible. The flight then tracks southeast across Montana and Wyoming, where the Rocky Mountain chain becomes increasingly prominent as the aircraft descends toward Denver. The High Plains of eastern Colorado are visible during the final approach.
