Sit on the Left side of the plane for the best views on flights from Washington to Lima. While takeoff from DCA favors the right side, the landing approach into Lima from the left provides more dramatic and sustained scenery—the Andes Mountains are the dominant visual feature of this entire route and are best viewed from the left during descent. The mountain views outweigh the brief Potomac/D.C. scenery on departure.

During takeoff from Ronald Reagan Washington National (DCA), sit on the Right side for the best views. Right-side seats offer views of the Potomac River and Washington D.C.'s urban grid during the initial climb-out over northern Virginia. The Appalachian foothills become visible to the west as altitude increases. Notable sights include: Potomac River, Washington D.C. street grid, Arlington/Alexandria urban sprawl, Blue Ridge Mountains (distant western horizon).

When landing at Jorge Chavez International (LIM), sit on the Left side for the best views. Left-side seats provide excellent views of the Andes Mountains as the aircraft descends into Lima from the southeast. The Pacific coastline and Lima's sprawling urban area become increasingly visible during final approach. Notable sights include: Andes Mountains (eastern backdrop), Pacific Ocean coastline, Lima urban area and Callao port, Rimac River valley.

The flight from Ronald Reagan Washington National (DCA) to Jorge Chavez International (LIM) takes Approximately 5 hours 45 minutes to 6 hours 15 minutes.

The flight path crosses the Gulf of Mexico (visible as open water with occasional cloud formations), then passes over the Yucatan Peninsula and Caribbean coast of Mexico/Central America. Over Central America, the Sierra Madre mountain ranges are visible on the right side. As the aircraft continues south, it crosses into Colombia and Ecuador, where the Andes Mountains become increasingly prominent on the right side of the aircraft. The Amazon basin appears as dense green forest with river systems visible as dark linear features. The approach to Peru brings the Andes into sharp focus on the right/eastern side before the final left turn toward Lima's coastal approach.
