Sit on the Right side of the plane for the best views on flights from San Juan to Madrid. Right-side seats capture the most dramatic scenery: the Caribbean departure over Puerto Rico's northern coast and Atlantic, plus the mid-Atlantic views of the Azores archipelago (if visible during daylight hours on the outbound leg). Left-side seats offer good Madrid approach views but miss the oceanic highlights of the transatlantic crossing.

During takeoff from Fernando Luis Ribas Dominicci (SIG), sit on the Right side for the best views. Right-side seats capture the northern Puerto Rico coastline and the Atlantic Ocean immediately after departure. San Juan's runways typically depart eastward or northeastward, positioning right-side passengers to see the island's northern shore, reef systems, and open Atlantic. Notable sights include: Northern Puerto Rico coastline with reef breaks, Atlantic Ocean, El Yunque National Forest (visible as forested ridge to the southeast), San Juan metropolitan area receding below.

When landing at Barajas (MAD), sit on the Left side for the best views. Left-side seats offer views of the Iberian Peninsula's interior and the approach to Madrid. As the aircraft descends over central Spain, left-side passengers see the Meseta Central plateau, the Sierra de Guadarrama mountains, and the sprawl of Madrid itself before final approach. Notable sights include: Sierra de Guadarrama mountain range, Meseta Central plateau, Madrid metropolitan area, Tagus River valley.

The flight from Fernando Luis Ribas Dominicci (SIG) to Barajas (MAD) takes Approximately 8.5 to 9.5 hours.

The flight path crosses the Atlantic Ocean for roughly 7 hours. The Azores archipelago (Portugal, ~38°N 28°W) may be visible during daylight portions of the flight, appearing as small dark islands surrounded by deep blue ocean. The Mid-Atlantic Ridge and associated deep ocean basins dominate the crossing—no visible landmarks except occasional cloud formations. As the aircraft approaches Europe, the Portuguese coast becomes visible, followed by the Spanish interior plateau (Meseta Central) with its characteristic brown coloring and sparse vegetation. The Sierra de Guadarrama marks the final approach corridor into Madrid.
