Sit on the Right side of the plane for the best views on flights from Barcelona to Los Angeles. The right side offers the better overall experience. While left is superior at takeoff, the right side captures the Atlantic crossing views and delivers the more dramatic arrival sequence over the Los Angeles Basin with the mountain backdrop. Over the Atlantic and Greenland, the right side also faces slightly more toward the northern ice and Greenland coastline on the great circle route.

During takeoff from Barcelona (BCN), sit on the Left side for the best views. Barcelona's runways 25L/25R send aircraft westward over the city, putting the left side facing south toward the Mediterranean coastline, the Llobregat delta, and the Montjuïc hill. You get a clear view of the city grid and the port before the aircraft turns northwest. Notable sights include: Port of Barcelona and breakwaters, Montjuïc hill, Llobregat river delta, Barcelona city grid extending to Tibidabo.

When landing at Los Angeles International (LAX), sit on the Right side for the best views. LAX's runways 24L/24R have aircraft approaching from the east over the Los Angeles Basin, putting the right side facing north toward downtown LA, the Hollywood Hills, and the Santa Monica Mountains. The left side faces south toward the Pacific Ocean and the South Bay, which is less visually varied. Notable sights include: Downtown Los Angeles skyline, Hollywood Hills and Griffith Observatory ridge, Santa Monica Mountains, Santa Monica Bay coastline.

The flight from Barcelona (BCN) to Los Angeles International (LAX) takes Approximately 11 to 12 hours.

The great circle route from Barcelona to LAX arcs northwest over the Pyrenees, crosses the Bay of Biscay, tracks over southern Ireland and the North Atlantic, passes south of Greenland and over the Labrador Sea, crosses Newfoundland and the Canadian Maritime provinces, then transits the northeastern United States before descending over the Rockies and Mojave Desert into Southern California. Greenland's ice sheet edge may be visible from altitude on the northern arc, and the Canadian Rockies are often visible during the descent phase.
