Sit on the Left side of the plane for the best views on flights from Chengdu to Madrid. Left seats capture the dramatic climb-out from the Sichuan Basin and the superior landing approach over the Tagus River and Sierra de Guadarrama. The takeoff advantage is moderate, but the landing view is significantly better on the left.

During takeoff from Shuangliu (CTU), sit on the Right side for the best views. Chengdu typically departs eastbound (Runway 01L/01R or 19L/19R depending on wind). Right-side seats face the Chengdu Plain and the eastern approach to the Longquan Mountains, offering immediate terrain contrast. Left seats see the city itself but less dramatic topography during climb-out. Notable sights include: Longquan Mountains (eastern ridge, visible as a rising line of peaks), Chengdu urban sprawl (grid pattern below), Funan River (thin silver line threading through the plain), Qingbaijiang District industrial zone (geometric patterns to the northeast).

When landing at Barajas (MAD), sit on the Left side for the best views. Madrid typically lands westbound (Runway 32L/32R). Left-side seats on approach offer views of the Tagus River valley, the Sierra de Guadarrama to the north, and the approach path over the Castilian plateau. Right seats see less distinctive terrain during final descent. Notable sights include: Tagus River (major waterway, visible as a winding brown-gray ribbon), Sierra de Guadarrama (northern mountain range, snow-capped in winter), Madrid urban sprawl (extensive grid and radial streets), Barajas Airport runways (parallel concrete strips).

The flight from Shuangliu (CTU) to Barajas (MAD) takes Approximately 12.5–13 hours block time (westbound routing over Central Asia, Iran, Turkey, and southern Europe).

The flight path crosses the Tibetan Plateau's eastern edge (visible as high, barren terrain around 10,000–14,000 feet elevation), then descends into the Tarim Basin and Taklamakan Desert (vast, featureless sandy expanses). Over Central Asia, the Tian Shan and Pamir mountain ranges appear as major ridges. The route then crosses the Caspian Sea (large body of water, visible as a distinct color change), passes over the Caucasus Mountains, and continues over Anatolia (Turkey) with the Black Sea visible to the north. The final approach crosses the Iberian Peninsula's interior plateau before reaching Madrid.
