Porto to London flight path: OPO to STN

Sit on the Right side of the plane for the best views on flights from Porto to London. The right side offers sustained coastal scenery during departure and early cruise—Porto's riverfront, the Atlantic shoreline, and Galicia's rugged coast—while the left side's reward is a brief London skyline glimpse only near touchdown; most of the flight over the Bay of Biscay is open ocean regardless of side.

During takeoff from Porto (OPO), sit on the Right side for the best views. Departing OPO on runway 17, the aircraft climbs south over the Douro estuary before banking west and then north out over the Atlantic, keeping the Porto waterfront and the rugged Galician coastline on the right side of the cabin as the climb continues. Notable sights include: Douro River mouth and Porto's historic riverfront, Matosinhos harbor, Atlantic coastline of northern Portugal, Cabo Fisterra headland on the Galician coast.

When landing at Stansted (STN), sit on the Left side for the best views. On approach to STN's runway 22, the aircraft typically arrives from the northeast, giving passengers on the left side a clear view south toward London's skyline before the final turn onto the runway over the Essex countryside. Notable sights include: London skyline (Shard, Canary Wharf towers), Thames Estuary, Essex farmland and reservoirs, Stansted's surrounding patchwork fields.

The flight from Porto (OPO) to Stansted (STN) takes about 2 hours 50 minutes. The shortest flight path between them is 847 miles (1,363 km); winds and air traffic control usually add a few percent.

Open waters of the Bay of Biscay, with occasional visibility of the French Atlantic coast near Brittany if the route drifts east before crossing into English airspace.
