Sit on the Left side of the plane for the best views on flights from Taipei to Hanoi. While takeoff favors the right for Taiwan's northern coast, the landing approach over the Red River delta and views of Hanoi's geography from the left side provide more sustained and distinctive visual interest for the majority of the flight's final phase.

During takeoff from Chiang Kai Shek International (TPE), sit on the Right side for the best views. TPE typically departs runway 05L/05R (northeast heading). Right-side seats face the Taiwan Strait and northern Taiwan's coastline during initial climb, with clear views of the Yangmingshan volcanic plateau and the northern coast receding below. Notable sights include: Taiwan Strait (west), Yangmingshan volcanic plateau (north), Keelung city and harbor (northeast), northern Taiwan coastline.

When landing at Noibai International (HAN), sit on the Left side for the best views. HAN typically lands runway 05L/05R (northeast heading). Left-side seats during descent offer views of the Red River delta's agricultural patchwork and the approach path over the river itself, with Hanoi's urban core visible to the left as you descend toward the airport northwest of the city. Notable sights include: Red River delta (agricultural fields and waterways), Red River main channel, Hanoi city center (distant, left side), limestone karst formations (southwest).

The flight from Chiang Kai Shek International (TPE) to Noibai International (HAN) takes Approximately 2 hours 15 minutes.

The flight crosses the Taiwan Strait (northwest from TPE), passes over the Gulf of Tonkin's northern waters, and approaches the Red River delta from the southeast. The Hainan Island coastline may be visible to the left (southwest) during cruise at altitude, appearing as a distant landmass on the horizon. The approach to HAN descends over the delta's agricultural landscape with the Red River as the primary geographic reference.
