Sit on the Right side of the plane for the best views on flights from London to Singapore. The right side delivers the more dramatic takeoff experience over London, and through the cruise the right side tracks the Bay of Bengal coastline and parts of the Andaman Sea. The landing view on the left is excellent but briefer. Right side wins overall for the London departure alone, which is the most visually memorable portion of this route.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures heading east on runway 27L/27R (westerly wind common) or 09R mean a right-side seat gives views over central London as the aircraft climbs and turns southeast. You'll track over the Thames, with the City of London, Canary Wharf towers, and the river bends clearly visible before crossing the M25. Notable sights include: Thames river bends through central London, Canary Wharf cluster, The O2 dome at Greenwich, M25 orbital motorway ring.

When landing at Seletar (XSP), sit on the Left side for the best views. Seletar Airport sits in the north of Singapore island, and aircraft typically approach from the south or southeast over the Strait of Johor. A left-side seat on approach gives views over central Singapore — the Marina Bay skyline, the reservoir system, and the causeway to Malaysia are all visible on the left as you descend. Notable sights include: Marina Bay Sands and central Singapore skyline, Lower Seletar Reservoir, Johor Bahru across the Strait of Johor, Causeway linking Singapore to Malaysia.

The flight from Heathrow (LHR) to Seletar (XSP) takes Approximately 13 to 14 hours.

The route typically tracks southeast over Europe crossing the Alps, then over Turkey and the Levant coast, descending over the Persian Gulf region near Oman, crossing the Indian subcontinent over central India (passing near Mumbai and Chennai), then over the Bay of Bengal, the Andaman Islands, the Malay Peninsula over Thailand and Malaysia, before descending into Singapore from the north.
