Sit on the Right side of the plane for the best views on flights from London to Delhi. The right side wins overall because the takeoff view over London is genuinely spectacular and hard to beat, and during the cruise the right side also faces south, giving better views of the Hindu Kush and Himalayan foothills as the route passes over Afghanistan and Pakistan. The left side has a slight edge on landing but not enough to overcome the right side's advantages at departure and en route.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures on the eastbound runway 27L/27R head west before turning southeast. A right-side seat gives you the Thames valley, central London landmarks, and the City skyline as the aircraft banks left over Surrey. Left side faces away toward Berkshire and the M4 corridor with little of interest. Notable sights include: Thames river bends through central London, Wembley Stadium arch, The Shard and City of London cluster, Windsor Castle and Great Park.

When landing at Indira Gandhi International (DEL), sit on the Left side for the best views. IGI Delhi typically uses runways 28/29 for arrivals from the west, meaning the aircraft approaches from the east over the city. A left-side seat on final approach gives a clear view over South and Central Delhi including Connaught Place, India Gate, and the Yamuna river. Right side faces north toward the less distinctive outer suburbs. Notable sights include: Yamuna river, India Gate and Rajpath axis, Connaught Place circular road pattern, Old Delhi dense urban grid.

The flight from Heathrow (LHR) to Indira Gandhi International (DEL) takes Approximately 8 to 9 hours.

The route tracks southeast over Germany and Austria, then over the Balkans and Turkey, crossing into Iran over the Zagros Mountains. It then passes over Afghanistan including the Hindu Kush range before descending over Pakistan's Punjab plains and crossing the Indus river system. The Hindu Kush and Karakoram foothills are visible from the right side at cruise altitude as a dramatic corrugated snowcapped terrain roughly 5 to 6 hours into the flight.
