Sit on the Left side of the plane for the best views on flights from Taipei to Dallas-fort Worth. The left side wins overall due to the dramatic Taiwan departure views — the Danshui estuary, Taipei basin, and the northern coastline are genuinely spectacular on climb-out. The trans-Pacific crossing offers little on either side, and DFW arrival views are relatively flat on both sides, so the takeoff experience tips the balance to the left.

During takeoff from Chiang Kai Shek International (TPE), sit on the Left side for the best views. TPE departures typically use runways 05L/05R heading northeast, which puts the left (north) side facing toward Taipei city and the northern Taiwan coastline. As the aircraft banks right to head east over the Pacific, the left side gets a clear view of the Danshui River estuary and the urban sprawl of Taipei basin before the Central Mountain Range comes into view. Notable sights include: Danshui River estuary and mouth, Taipei city basin and 101 tower, northern Taiwan coastline along the Taiwan Strait, Yangmingshan volcanic highlands to the north.

When landing at Dallas Fort Worth International (DFW), sit on the Right side for the best views. DFW arrivals from the west typically use runways 17L/17R or 18L/18R heading south, placing the right (west) side facing toward Fort Worth and the open Texas plains. The left side faces Dallas city center but the right gives a broader panoramic view of the DFW metroplex spread across the flat prairie as you descend. Notable sights include: Fort Worth downtown skyline to the southwest, Lake Grapevine to the north, the flat Texas prairie grid of roads and farmland, DFW airport taxiway and runway complex below.

The flight from Chiang Kai Shek International (TPE) to Dallas Fort Worth International (DFW) takes Approximately 14 to 15 hours nonstop.

The great circle route from TPE to DFW tracks northeast over the North Pacific, passing south of Japan's Ryukyu Islands chain early in the flight, then arcing across the open North Pacific Ocean for the majority of the route. The Aleutian Islands chain of Alaska may be visible as distant specks on the northern horizon at cruise altitude roughly 6 to 8 hours in. The route then descends over the Pacific Northwest coast of North America, crossing the Rocky Mountains of Colorado or New Mexico depending on routing, before the long descent across the flat Texas panhandle and plains toward DFW.
