Sit on the Right side of the plane for the best views on flights from Madrid to San Sebastian. Right side wins overall because the northbound departure offers more dramatic mountain scenery (Sierra de Guadarrama) than the landing approach, and the flight path itself runs roughly north-northeast, keeping the Pyrenees and Basque terrain more consistently visible on the right side during cruise.

During takeoff from Barajas (MAD), sit on the Right side for the best views. Right side seats capture the climb-out northward over Madrid's urban sprawl and the Sierra de Guadarrama mountain range rising dramatically to the north. Left side faces the flat southern plains with minimal visual interest. Notable sights include: Sierra de Guadarrama (northern horizon), Madrid city grid and Retiro Park (directly below during initial climb), Tagus River valley (western side), Toledo hilltop city visible southeast on clear days.

When landing at San Sebastian (EAS), sit on the Left side for the best views. Left side provides the best views during descent into San Sebastian. The approach typically comes from the south or southeast, and left seats face the Cantabrian coast, the Bay of Biscay, and the distinctive Basque coastline with its dramatic cliffs and beaches. Notable sights include: Bay of Biscay (Bahía de Vizcaya), Basque coastal cliffs and beaches near San Sebastian, Pyrenees foothills (southern horizon), Donostia/San Sebastian city nestled between Monte Urgull and Monte Igueldo.

The flight from Barajas (MAD) to San Sebastian (EAS) takes Approximately 1 hour 15 minutes.

The flight path crosses the Sistema Central mountain range (Sierra de Guadarrama and Sierra de Somosierra), then transitions into the Basque Country's rolling green hills. The Ebro River valley and its tributaries are visible from altitude in the northern portion. The landscape shifts from the arid central plateau to the lush, forested terrain of the Basque region. On clear days, the Pyrenees form a distant northern horizon for much of the cruise phase.
