Sit on the Right side of the plane for the best views on flights from London to Denpasar. Right side wins overall due to the spectacular London departure views over the Thames and City skyline, which are among the best urban aerial views in the world. The landing advantage on the left is real but shorter in duration. For the long cruise over the Middle East, Indian subcontinent, and Bay of Bengal, neither side has a decisive edge, though right side may catch the Arabian Peninsula coastline and Sri Lanka depending on exact routing.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures heading east on runway 27L/27R (westerly wind, most common) initially track over west London before turning. Right side gives you the Thames snaking through central London, the City skyline, and Canary Wharf. Left side gets suburban sprawl toward Slough and Windsor, which is less dramatic unless you catch Windsor Castle. Notable sights include: Thames River bends through central London, Canary Wharf tower cluster, The Shard and City of London skyline, Windsor Castle (left side, if departing eastward).

When landing at Bali International (DPS), sit on the Left side for the best views. Ngurah Rai Airport sits on a narrow isthmus with the Indian Ocean to the south and Benoa Harbour to the north. Runway 09 approaches from the west over open water, and the left side gives you the Bukit Peninsula cliffs and the southern Bali coastline including Kuta Beach as you descend. Right side faces north toward Benoa Harbour and the flat urban sprawl of Denpasar. Notable sights include: Kuta Beach and its long straight shoreline, Bukit Peninsula limestone cliffs, Benoa Harbour and its causeway, Ngurah Rai Airport peninsula visible below on final approach.

The flight from Heathrow (LHR) to Bali International (DPS) takes Approximately 13 to 14 hours nonstop.

Typical routing tracks southeast over France and the Alps, then across the Adriatic and Greece, over the eastern Mediterranean and into the Middle East passing near the Persian Gulf. The flight then crosses the Arabian Sea, the western coast of India (Mumbai area visible), across the Deccan Plateau, over Sri Lanka, and then the Bay of Bengal before crossing the Malay Peninsula or Sumatra to reach Bali. The Alps, the Persian Gulf coastline, the Indian coastline near Mumbai, and the green mountainous spine of Sumatra are the most visually striking features en route.
