Sit on the Left side of the plane for the best views on flights from Naples to London. The left side wins on both ends: a spectacular Bay of Naples and Vesuvius departure, and a Thames-London approach into Heathrow, while the right side spends most of the flight over the Apennines briefly then featureless cloud-covered France and the Channel with less visual payoff.

During takeoff from Capodichino (NAP), sit on the Left side for the best views. Departing NAP northbound, the left side offers a dramatic view back over the Bay of Naples, Mount Vesuvius, and the Sorrento peninsula before the route turns north over the Apennines. This is one of the most distinctive departure views in Europe. Notable sights include: Mount Vesuvius, Bay of Naples, Sorrento Peninsula, Capri (distant).

When landing at Heathrow (LHR), sit on the Left side for the best views. On approach into LHR from the south or east, the left side typically catches the Thames winding through London with recognizable landmarks like Canary Wharf, the City, and the river bends before landing at Heathrow. Approach paths vary but the Thames corridor is usually visible on this side. Notable sights include: River Thames, Canary Wharf skyline, Central London skyline, Richmond Park green belt.

The flight from Capodichino (NAP) to Heathrow (LHR) takes 2h 40m.

The route crosses the Apennine Mountains of central Italy, the Ligurian or Tyrrhenian coastline near Genoa, the French Alps foothills or Rhône valley depending on routing, and the English Channel before making landfall over southern England.
