Sit on the Left side of the plane for the best views on flights from Atlanta to San Juan. While the right side has a slight edge at Atlanta departure, the left side wins decisively at the San Juan arrival with Old San Juan, El Morro, and San Juan Bay — genuinely spectacular and historically rich scenery. Over the flight path, the left side also tracks the Florida coastline and the northern Caribbean island chain more closely.

A left-side seat gives views of Old San Juan's historic peninsula, San Juan Bay, and the Atlantic coastline during approach. The left side faces north toward the ocean and the dramatic fortifications of El Morro. Notable sights include: Old San Juan peninsula and El Morro fortress, San Juan Bay, Condado lagoon and beachfront strip, El Yunque rainforest massif to the east on the horizon.
