Sit on the Left side of the plane for the best views on flights from Doha to Barcelona. Left side wins at both ends of the flight. During the cruise, the left side also faces south over the Arabian Peninsula, the Red Sea crossing, and the North African coast — more visually interesting than the right side's view over open water and featureless terrain for much of the route.

During takeoff from Doha International (DOH), sit on the Left side for the best views. Departing Doha, aircraft typically use runway 16/34. On a northwestbound departure, the left side faces west over Doha city and the shallow turquoise waters of the Persian Gulf. You get a clear view of the Qatar peninsula's coastline and the dense urban core of Doha including the West Bay skyline. Notable sights include: West Bay skyscraper cluster, Qatar peninsula coastline, shallow turquoise Persian Gulf waters, Doha corniche waterfront arc.

When landing at Barcelona (BCN), sit on the Left side for the best views. Barcelona's runway 25L/07R means arrivals from the east approach over the Mediterranean. On the standard ILS approach to runway 25L heading west, the left side faces south and gives you the Mediterranean coastline, the city's beachfront, and the Montjuïc hill. The right side faces inland toward the Collserola ridge but at a less dramatic angle. Notable sights include: Mediterranean coastline and Barcelona beaches, Montjuïc hill, Barcelona port and harbor, Llobregat river delta.

The flight from Doha International (DOH) to Barcelona (BCN) takes Approximately 6.5 to 7 hours.

The route tracks northwest from Qatar over Saudi Arabia, crosses the Red Sea near Jeddah, passes over Egypt and the Nile Delta, then crosses the Mediterranean toward Sicily and Sardinia before reaching the Iberian coast. Notable features include the Red Sea's narrow blue corridor, the Nile Delta's distinctive green fan shape visible from cruise altitude, the Italian island of Sardinia, and the Balearic Islands (Mallorca, Ibiza) shortly before descent into Barcelona.
