Sit on the Left side of the plane for the best views on flights from Atlanta to San Juan. The left side wins overall because the SJU landing approach over Old San Juan and El Morro is one of the most visually spectacular arrivals in the Caribbean, and the left side also captures the Florida coastline and the Bahamas chain during the cruise portion of the flight.

During takeoff from The William B Hartsfield Atlanta International (ATL), sit on the Right side for the best views. ATL primarily uses its south complex runways (28R/28L) departing westward before turning southeast, or runway 10 departing eastward. On a southeast departure toward San Juan, the right side gives you the Atlanta skyline to the north and Stone Mountain's distinctive granite dome to the northeast as you climb out over the eastern suburbs. Notable sights include: Atlanta downtown skyline, Stone Mountain granite dome, Lake Lanier reservoir to the north, Piedmont foothills rolling east toward Georgia.

When landing at Luis Munoz Marin International (SJU), sit on the Left side for the best views. SJU's primary landing runway is 10, approaching from the west over the Atlantic and San Juan Bay. On this approach, the left side gives you the full panorama of Old San Juan on its peninsula, San Juan Bay, and the El Morro and San Cristobal fortresses clearly visible on the headland. Notable sights include: Old San Juan peninsula and El Morro fortress, San Juan Bay, Condado lagoon and beachfront, El Yunque rainforest massif to the southeast.

The flight from The William B Hartsfield Atlanta International (ATL) to Luis Munoz Marin International (SJU) takes Approximately 3 hours 15 minutes to 3 hours 30 minutes.

The flight tracks southeast over Georgia and South Carolina, then crosses the Florida peninsula near Orlando, offering views of Lake Okeechobee (one of the largest freshwater lakes in the US) before crossing the Florida Straits. The route then passes over or near the Bahamas island chain — Great Abaco, Eleuthera, and the Exumas are often visible as thin strips of pale sand and turquoise shallow water against the deep blue Atlantic. The deep blue of the open Atlantic dominates the final hour before Puerto Rico's green mountainous interior comes into view.
