Sit on the Right side of the plane for the best views on flights from Kulu to London. The right seat wins overall because the KUU departure on the right is genuinely spectacular — few airport departures in the world match the Himalayan gorge scenery of the Beas valley and Pir Panjal peaks. The London arrival advantage on the left is real but more modest. Across the mid-flight, the right side also picks up better views of the Hindu Kush, southern Turkmenistan plains, and the Caspian Sea coastline depending on exact routing.

During takeoff from Kullu Manali (KUU), sit on the Right side for the best views. Kullu Manali Airport (KUU) sits in the Beas River valley and typically uses Runway 14 for departures heading southeast, then aircraft must execute a climbing turn northward to exit the valley. The right side gives you the Pir Panjal range and the dramatic Rohtang Pass area as the aircraft climbs steeply out of the gorge. The Beas River gorge and terraced hillside villages are directly below on the right during initial climb. Notable sights include: Rohtang Pass (3,978m) to the north, Pir Panjal Range peaks on the right, Beas River gorge below, terraced agricultural fields on valley slopes.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow primarily uses easterly approaches on Runways 27L/27R in westerly winds, meaning the aircraft tracks in from the east over London. The left side on final approach gives a clear view over central London — the Thames, the City, and Canary Wharf are visible to the south-left. On westerly runway departures the geometry reverses, but arrivals from the east on the left seat are the consistent winner. Notable sights include: River Thames snaking through central London, Canary Wharf tower cluster, Windsor Castle and Windsor Great Park to the west, M25 motorway ring.

The flight from Kullu Manali (KUU) to Heathrow (LHR) takes Approximately 9 to 10.5 hours, though KUU has very limited direct connectivity and this route would almost certainly involve a connection, typically via Delhi (DEL). A DEL-LHR leg alone is around 9 hours..

Departing the Himalayas northwestward, the route typically crosses the Hindu Kush range over Afghanistan or Pakistan, then tracks over the Caspian Sea (visible as a large inland sea), across southern Russia or Ukraine depending on current airspace routing, then over Poland and Germany before descending into the UK. The Caspian Sea crossing is a distinctive midpoint feature visible from both sides.
