Sit on the Left side of the plane for the best views on flights from Singapore to Christchurch. The left side wins overall because the Southern Alps on approach into Christchurch are one of the most dramatic mountain views available on any approach in the Southern Hemisphere, and the left side also captures the Tasman Sea and western coastline of the South Island during the final descent. The takeoff right-side advantage is real but shorter-lived.

During takeoff from Singapore Changi (SIN), sit on the Right side for the best views. Changi typically departs on runway 02C/02L heading roughly north, so the right (east) side looks out over the Strait of Singapore and the southern islands. You get a clear view of the Riau Islands and the busy shipping lanes of the Singapore Strait before the aircraft turns southeast. Notable sights include: Singapore Strait shipping lanes, Batam Island (Indonesia), Riau Islands archipelago, Changi coastline and reclaimed land.

When landing at Christchurch International (CHC), sit on the Left side for the best views. Christchurch typically lands on runway 02 heading north or runway 29 heading west depending on wind. On the common northward approach from the south, the left (west) side gives you the Southern Alps running along the spine of the South Island, with the Canterbury Plains stretching between the mountains and the city. On a westerly approach, the left side still captures the Alps and the city layout. Notable sights include: Southern Alps (Kā Tiritiri o te Moana), Canterbury Plains, Banks Peninsula volcanic remnant, Christchurch city grid.

The flight from Singapore Changi (SIN) to Christchurch International (CHC) takes Approximately 10 to 11 hours.

The route tracks southeast from Singapore across the Java Sea, passing over or near Bali and the Lesser Sunda Islands of Indonesia, then crosses the Timor Sea and the remote northwest coast of Australia near the Kimberley region. The flight then crosses the vast Australian interior — largely flat red desert with occasional dry lake beds and the Nullarbor Plain visible if flying over southern Australia. The route then crosses the Great Australian Bight and the Southern Ocean before making landfall on the South Island of New Zealand near the West Coast, where the Southern Alps become visible.
