Sit on the Left side of the plane for the best views on flights from Charlotte to San Juan. The left side wins overall because the landing approach into SIG over San Juan Bay with Old San Juan and El Morro in view is one of the most visually dramatic urban approaches in the Caribbean. The takeoff advantage on the right is real but modest — Charlotte's skyline is relatively small. The left side also picks up Atlantic coastline views during the cruise descent toward Puerto Rico.

During takeoff from Charlotte Douglas International (CLT), sit on the Right side for the best views. CLT's primary departure runway 18C/36C runs roughly north-south. Southbound departures on 18C put the right side facing west toward uptown Charlotte's skyline and then the Piedmont foothills. Left side faces east toward flat suburban sprawl with less visual interest. Notable sights include: Uptown Charlotte skyline, Lake Norman to the northwest, Catawba River corridor, Piedmont foothills rolling toward the Blue Ridge.

When landing at Fernando Luis Ribas Dominicci (SIG), sit on the Left side for the best views. SIG (Isla Grande Airport) sits on a peninsula in San Juan Bay. Landings on runway 10 approach from the west over the bay, putting the left side facing south toward Old San Juan's historic fortifications, the Atlantic coastline, and the dense urban fabric of metropolitan San Juan. Right side faces north over open water with less to see on final. Notable sights include: Old San Juan and Castillo San Felipe del Morro, San Juan Bay, Condado lagoon and beachfront, El Yunque rainforest ridgeline to the east.

The flight from Charlotte Douglas International (CLT) to Fernando Luis Ribas Dominicci (SIG) takes Approximately 2 hours 45 minutes to 3 hours.

The flight tracks southeast from the Carolinas over the Atlantic, crossing the Outer Banks of North Carolina early in the flight. The mid-flight portion is entirely over open ocean with the Gulf Stream visible as a slightly darker blue band in the Atlantic. As the flight descends toward Puerto Rico, the northern coast of Hispaniola may be visible on the horizon to the south, and the Virgin Islands chain can sometimes be seen to the east on clear days. The Puerto Rican coastline appears on approach with its green mountainous interior and narrow coastal plain.
