Sit on the Left side of the plane for the best views on flights from Lisbon to London. Left side wins at both ends of the flight. Over the Bay of Biscay and into southern England the left side also tracks closer to the French and Spanish coastlines during the northward routing, occasionally offering glimpses of the Cantabrian coast and Brittany peninsula in the distance on clear days.

During takeoff from Lisboa (LIS), sit on the Left side for the best views. Lisbon's runway 03 departure heads north, putting the left side facing west over the Tagus estuary and the Atlantic coast. You get a clear view of the wide Tagus mouth, the 25 de Abril Bridge, and the city spreading across the hills before the aircraft turns north. Notable sights include: Tagus estuary and its wide mouth opening to the Atlantic, 25 de Abril suspension bridge, Belém district and Tower, Arrábida Peninsula coastline to the south.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's most common landing direction is runway 27L/27R, approaching from the east heading west. Left-side seats face south, giving views over central London, the Thames, and the city skyline during the approach. Right side faces north over suburban Middlesex with far less of interest. Notable sights include: Thames River winding through central London, City of London skyline and Canary Wharf towers, Windsor Castle and Windsor Great Park to the west, Wembley Stadium arch visible to the north of the approach track.

The flight from Lisboa (LIS) to Heathrow (LHR) takes Approximately 2 hours 20 minutes to 2 hours 35 minutes.

The route crosses the Bay of Biscay, offering open ocean views with no landmarks at altitude. Over northern Spain the Cantabrian Mountains are visible as a coastal ridge. Crossing into France, the route passes over Brittany or the Loire Valley depending on ATC routing. Southern England brings the patchwork of Devon and Somerset farmland before the Thames Valley approach.
