Sit on the Right side of the plane for the best views on flights from Perth to Singapore. The right side wins overall. The Perth departure on the right delivers the most dramatic urban and geographic scenery of the flight — the Swan River and city together make for a genuinely memorable climb-out. The Singapore approach on the left is excellent, but the right side still gets partial views of the southern coastline and Batam. Given that the Perth departure view is the clearest highlight of the route, right side edges it.

During takeoff from Perth International (PER), sit on the Right side for the best views. Perth International typically departs northward on runway 03, so the right (east) side gives you the Swan River snaking through the city, the Perth CBD skyline, and Kings Park on the escarpment above the river. The left side faces west toward the Indian Ocean coastal plain with less visual interest on climb-out. Notable sights include: Swan River and its distinctive bends through the suburbs, Perth CBD glass towers, Kings Park on the Mount Eliza ridge, Darling Scarp escarpment to the east.

When landing at Singapore Changi (SIN), sit on the Left side for the best views. Changi typically lands on runway 02L/02R from the south, approaching over the Strait of Singapore from the south. The left (west) side gives you views over the southern Singapore coastline, Sentosa Island, the massive container port at Tanjong Pagar, and the city skyline including Marina Bay. The right side faces east toward the open South China Sea and Batam Island. Notable sights include: Marina Bay Sands and CBD skyline, Sentosa Island and its causeway, Tanjong Pagar container terminal (one of the world's busiest), Strait of Singapore shipping lanes.

The flight from Perth International (PER) to Singapore Changi (SIN) takes Approximately 5 hours 15 minutes.

The route tracks north-northeast from Perth across the flat, largely featureless Western Australian interior and the Timor Sea. Around the midpoint you cross the Indonesian archipelago — Java and Sumatra are visible below with their volcanic peaks, dense tropical forest, and coastal cities. The Sunda Strait between Java and Sumatra may be visible depending on exact routing. As you approach Singapore, the Riau Islands of Indonesia and the busy Malacca Strait shipping lanes become visible.
