Sit on the Right side of the plane for the best views on flights from Firenze to London. The right seat wins overall because the Florence departure view — with the historic city center, the Duomo, the Arno valley, and the Apennines — is genuinely spectacular and hard to beat. The landing view from the left is good but west London on approach is largely suburban. If you can only pick one side for the whole flight, right gives you the best single moment of the journey at takeoff.

During takeoff from Peretola (FLR), sit on the Right side for the best views. Peretola's runway 05/23 means departures typically head northeast or southwest. A northwestbound departure toward London will swing the aircraft so the right side faces southeast toward Florence city center and the Arno valley. The Apennine hills rising immediately east of the airport are clearly visible on the right during climb-out. Notable sights include: Florence historic center and Duomo dome, Arno River valley, Apennine foothills east of the airport, Fiesole hill town above the city.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's dominant runway orientation is 09/27 (east-west). Arrivals from the southeast typically use runway 27L or 27R, approaching from the east over London. On this approach the left side faces south, giving views over central London including the Thames, while the right side faces north toward suburban Middlesex. Left seat is the clear winner for the city approach. Notable sights include: Thames River and its distinctive bends through central London, Windsor Castle and Windsor Great Park to the west, Wembley Stadium arch visible to the north on left-side approach, the M25 motorway ring.

The flight from Peretola (FLR) to Heathrow (LHR) takes Approximately 2 hours 20 minutes to 2 hours 40 minutes.

After leaving Tuscany the route crosses the northern Apennines and the Po Valley, then tracks northwest over the Alps near the Mont Blanc massif or the Swiss plateau depending on routing. Over France the flight crosses the Loire Valley and Normandy agricultural plains. The English Channel crossing takes roughly 20-25 minutes, with the white cliffs of the Dover-Calais strait sometimes visible depending on exact routing. Over southern England the North Downs and Thames Valley are crossed before descent into Heathrow.
