Sit on the Right side of the plane for the best views on flights from Porto to Istanbul. While left offers excellent Porto departure views, right seats dominate the approach into Istanbul with the Bosphorus and Marmara Sea—the flight's most dramatic geographical feature. The landing views outweigh the takeoff advantage.

During takeoff from Porto (OPO), sit on the Left side for the best views. Left seats offer views of the Douro River valley as it winds inland from Porto, plus the Atlantic coastline receding northward. Right seats face inland terrain with less dramatic relief. Notable sights include: Atlantic Ocean coastline, Douro River estuary, Serra da Arrabida hills to the south, Aveiro Lagoon (visible at distance during climb).

When landing at Ataturk (IST), sit on the Right side for the best views. Right seats provide views of the Marmara Sea approach, the Bosphorus strait, and Istanbul's urban landscape spread across both European and Asian shores. Left seats see mostly inland Anatolian terrain. Notable sights include: Marmara Sea, Bosphorus Strait, European Istanbul (Golden Horn district), Asian Istanbul hills, Prince's Islands archipelago.

The flight from Porto (OPO) to Ataturk (IST) takes 4h 30m.

The flight path crosses the Mediterranean basin, passing over southern Spain (Sierra Nevada visible on clear days), the Balearic Sea, southern Italy (Calabria coast), Greece (Peloponnese and Aegean islands), and the Aegean Sea before reaching the Marmara Sea approach. The Pyrenees may be visible during initial climb if conditions permit. Major water crossings include the Mediterranean and Aegean seas.
