Sit on the Left side of the plane for the best views on flights from Louisville to San Juan. While takeoff offers interesting regional views, the landing approach into San Juan provides superior scenery with the dramatic contrast of open ocean, tropical coastline, and Caribbean island geography. The Caribbean waters and Puerto Rican landscape are more visually distinctive than the Ohio River valley.

During takeoff from Louisville Muhammad Ali International Airport (SDF), sit on the Right side for the best views. Right-side seats offer views of the Ohio River valley and the city of Louisville spreading eastward. The aircraft climbs southeastward from SDF, so right-side passengers see the river's curves and the urban sprawl before heading toward open terrain. Notable sights include: Ohio River (winding through Louisville), downtown Louisville skyline, Watterson Expressway corridor, surrounding bluegrass farmland.

When landing at Fernando Luis Ribas Dominicci (SIG), sit on the Left side for the best views. Left-side seats provide views of the Atlantic Ocean, the Puerto Rican coastline, and San Juan's urban area during approach. The aircraft descends from the northeast toward SIG, so left-side passengers see the Caribbean waters and the island's northern shore with the city sprawling along the coast. Notable sights include: Atlantic Ocean and Caribbean waters, Puerto Rico's northern coastline, San Juan metropolitan area, El Yunque National Forest (visible as green ridge to the southeast).

The flight from Louisville Muhammad Ali International Airport (SDF) to Fernando Luis Ribas Dominicci (SIG) takes Approximately 3 hours 45 minutes to 4 hours 15 minutes.

The flight path crosses the southeastern United States, passing over or near the Appalachian foothills (Tennessee/North Carolina border region), then over the Atlantic Ocean. Notable midpoint geography includes the Smoky Mountains visible to the east during early cruise, the Atlantic coastline near the Carolinas, and open ocean for the majority of the flight. The Gulf Stream's warm waters are crossed during the final oceanic leg, though not visually distinctive from altitude. No major islands are crossed until approaching Puerto Rico.
