Sit on the Right side of the plane for the best views on flights from Madrid to Doha. The left side wins at takeoff for Madrid and the Sierra de Guadarrama, but the right side captures the Mediterranean coast of Spain during the climb-out over the southeast, the entire length of the Arabian Peninsula approach, and the spectacular Doha Bay arrival. Right side has more sustained interest across the full flight.

During takeoff from Barajas (MAD), sit on the Left side for the best views. Barajas typically departs eastbound on runways 32L/32R or 18L/18R depending on wind. On a southeast-bound departure toward Doha, the left side gives you a view over central Madrid — the city grid, Casa de Campo park, and the Sierra de Guadarrama rising to the northwest. The right side faces open meseta with little of interest. Notable sights include: Sierra de Guadarrama (snow-capped ridge to the northwest), central Madrid city grid including the Retiro park green patch, Manzanares River valley, Barajas airport terminal complex receding behind.

When landing at Doha International (DOH), sit on the Right side for the best views. Doha's Hamad International (now the main hub, though the question references old Doha International) typically lands from the northwest or northeast. Approaching from the west-northwest over Qatar, the right side faces south over Doha Bay and the Persian Gulf, giving clear views of the city skyline, the West Bay skyscraper cluster, and the turquoise shallow waters of the Gulf. The left side faces inland desert. Notable sights include: West Bay Doha skyline cluster, Doha Bay turquoise shallows, Persian Gulf open water, Qatar peninsula coastline.

The flight from Barajas (MAD) to Doha International (DOH) takes Approximately 6 hours 30 minutes to 7 hours.

After departing Madrid the route crosses southeastern Spain and the Mediterranean near Alicante or Murcia, then overflies the central Mediterranean. The route then crosses over Egypt or Libya depending on routing, the Nile Delta is sometimes visible as a green fan against brown desert. The flight then crosses the Arabian Peninsula over Saudi Arabia — vast empty Rub al-Khali sand desert — before descending into Qatar over the flat Gulf coastal plain.
