Sit on the Left side of the plane for the best views on flights from Athens to London. Left side wins at both ends of the flight. Over Greece you get Athens, the Saronic Gulf, and the Aegean islands. Across the Balkans and central Europe the left side tracks closer to the Alps on some routings. Into London the left side delivers the Thames and the city skyline on a standard westerly approach.

During takeoff from Athens International Eleftherios Venizelos (ATH), sit on the Left side for the best views. Athens airport sits east of the city, and departures typically head west or northwest toward Europe. A left (south-facing) seat gives you the Saronic Gulf, the city of Athens, and the Acropolis hill as you climb out. The right side faces inland toward the relatively featureless Mesogeia plain. Notable sights include: Acropolis hill and central Athens, Saronic Gulf with Aegina island, Piraeus port and its harbor basin, Cape Sounion peninsula to the southeast.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's main runway axis runs roughly east-west. Westerly landings on 27L/27R bring you in over central London from the east, and the left (south-facing) seat gives you the Thames corridor, the City of London, and the South Bank. The right side looks north over suburban Middlesex with far less to see. Notable sights include: Thames River bending through central London, City of London skyline with the Shard and Canary Wharf towers, Windsor Castle and Windsor Great Park to the west, Wembley Stadium arch visible to the north on left-seat approach.
