Sit on the Right side of the plane for the best views on flights from Aviles to Barcelona. Right-side seats win overall because the takeoff view of the Cantabrian coast and Bay of Biscay is more visually distinctive and dramatic than the landing approach. The landing view on the left is functional but less scenic.

During takeoff from Asturias (OVD), sit on the Right side for the best views. Right-side seats capture the Cantabrian coastline and the Bay of Biscay immediately after departure. Asturias typically departs eastbound (runway 03), so right windows face north toward the coast and open water. Notable sights include: Bay of Biscay (Golfo de Vizcaya), Cantabrian coastal cliffs, Gijón city sprawl to the east, Picos de Europa mountains (distant, inland to the south).

When landing at Barcelona (BCN), sit on the Left side for the best views. Left-side seats offer views of the Llobregat River delta and the approach into Barcelona from the southwest. Aircraft typically land on runway 07L/07R, so left windows face the industrial delta, coastal wetlands, and the city's western sprawl during final descent. Notable sights include: Llobregat River delta (wetlands and agricultural patches), Mediterranean Sea, Barcelona's industrial zone and port facilities, Montjuïc hill (southwest of city center).

The flight from Asturias (OVD) to Barcelona (BCN) takes Approximately 1 hour 15 minutes.

The flight path crosses inland over the Castilian plateau after leaving the northern coast. Notable features include the Duero River basin (visible as a broad valley system), the Sistema Central mountain range (distant peaks on the southern horizon during cruise), and the transition from green Asturian terrain to the drier, flatter interior of Spain. No major cities are directly on the route; the aircraft passes east of Valladolid and west of Madrid.
