Sit on the Left side of the plane for the best views on flights from London to Kuala Lumpur. The KL approach on the left side delivers the most dramatic single moment of the flight — the Petronas Towers emerging from tropical haze with the Titiwangsa Range behind them. The takeoff right-side advantage over Surrey is pleasant but modest by comparison. Left wins overall for the arrival payoff.

During takeoff from Gatwick (LGW), sit on the Right side for the best views. Gatwick's dominant runway 26L/26R means westward departures swing south over the Surrey Hills and Sussex Weald. Right side gives you the North Downs ridge and the sprawl of Crawley below before the aircraft turns southeast toward the Channel. Left side faces north toward Redhill and suburban London, which is less interesting. Notable sights include: Surrey Hills AONB ridge, Crawley town grid below, the M23/M25 interchange, and the first glimpse of the South Downs to the south.

When landing at Kuala Lumpur International (KUL), sit on the Left side for the best views. KLIA typically uses runways 14L/14R or 32L/32R aligned roughly north-south. On approach from the northwest, the left side faces east toward Kuala Lumpur city center, giving clear views of the Petronas Towers skyline and the forested Titiwangsa Range behind it. Right side looks west over flat palm oil plantation grids with little of interest. Notable sights include: Petronas Twin Towers KL skyline, Titiwangsa Range foothills, the vast palm oil plantation grid of Selangor, and the Klang River valley.

The flight from Gatwick (LGW) to Kuala Lumpur International (KUL) takes Approximately 12 to 13 hours.

The route typically 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 Indian subcontinent over India and Sri Lanka before crossing the Bay of Bengal and the Andaman Sea, entering the Malay Peninsula from the northwest over southern Thailand and descending into Malaysia. Notable features include the Alps (visible as a white mountain chain), the Persian Gulf coastline, the Ganges plain, and the Sri Lanka coastline.
