Sit on the Left side of the plane for the best views on flights from London to Rome. Left side wins at both ends of the flight. During the cruise over the Alps and northern Italy, left-side passengers also get the better view of the Po Valley and the Apennine spine as the route tracks southeast, making left the consistent choice for the full journey.

During takeoff from Gatwick (LGW), sit on the Left side for the best views. Gatwick's primary departure runway is 26L/08R. Departing westbound on 26L, a left turn south is typical for Rome routing, giving left-side passengers views over the Surrey Hills and then the South Downs as the aircraft climbs out. Right-side passengers face north toward suburban London with less geographic interest. Notable sights include: Surrey Hills AONB, South Downs ridge, Crawley town grid below, English Channel coastline near Worthing.

When landing at Fiumicino (FCO), sit on the Left side for the best views. Fiumicino typically uses runways 16L/R for southerly landings or 34L/R for northerly approaches. On the common 16 approach heading (southbound), left-side passengers get a clear view over central Rome — the Tiber River, the Colosseum area, and the Vatican — as the aircraft descends over the city before turning west toward the coast. On a 34 approach from the sea, left side still captures the Roman coastline and the mouth of the Tiber. Notable sights include: Tiber River snaking through Rome, Vatican City and St Peter's dome, Colosseum and Roman Forum district, Fiumicino coastal lagoons and Tiber delta.

The flight from Gatwick (LGW) to Fiumicino (FCO) takes Approximately 2 hours 20 minutes.

The route crosses the French Alps or western Swiss Alps near Mont Blanc or the Gran Paradiso massif, then descends over the Po Valley of northern Italy — a vast flat agricultural plain clearly visible from altitude. The Apennine mountain chain runs parallel to the final approach corridor down the Italian peninsula. The Ligurian and Tyrrhenian coasts may be visible depending on exact routing.
