Sit on the Right side of the plane for the best views on flights from Porto to Zurich. The right side wins overall. At takeoff you get the full Douro estuary and Porto cityscape. During the flight the right side faces south, keeping the Pyrenees and then the French Massif Central in view as you cross northern Spain and France. The left side is better for the Zurich landing, but the takeoff and cruise scenery on the right is more consistently dramatic across the full flight.

During takeoff from Porto (OPO), sit on the Right side for the best views. Porto Airport's main departure runway 35 sends aircraft northward over the coast before turning east. The right side gets the Douro River estuary, the Atlantic coastline stretching south toward Espinho, and the city of Porto itself with its historic bridges visible during the initial climb. Notable sights include: Douro River estuary and mouth, Porto city center with Dom Luís I Bridge, Atlantic coastline south toward Espinho, Arrábida Bridge.

When landing at Zurich (ZRH), sit on the Left side for the best views. Zurich typically uses runway 14 or 28 for arrivals depending on wind. On the common runway 14 approach from the northwest, the left side faces south and east, giving clear views of Lake Zurich, the city center, and the Alps on the southern horizon. The right side faces north toward less dramatic terrain. Notable sights include: Lake Zurich (Zürichsee), Zurich city center and old town, Swiss Alps on the southern horizon (Glarus Alps and Säntis massif), Greifensee lake.

The flight from Porto (OPO) to Zurich (ZRH) takes Approximately 2 hours 30 minutes.

The route crosses northern Spain over Galicia and Castile, then the Pyrenees (visible as a major snow-capped east-west barrier), followed by southern France over the Languedoc and Rhône Valley corridor, then the Jura Mountains before descending into Switzerland. The Pyrenees crossing near the midpoint is the most visually dramatic feature of the cruise phase.
