Sit on the Left side of the plane for the best views on flights from Washington to San Jose. While takeoff favors the right for D.C. views, the landing approach over Costa Rica's Central Valley and volcanic terrain on the left provides more dramatic and sustained scenery. The left side captures the geological highlight of the entire flight—the approach to the volcanic highlands that define Costa Rica's geography.

During takeoff from Washington Dulles International (IAD), sit on the Right side for the best views. Right side offers views of the Potomac River and Washington, D.C. landmarks during climb-out. The typical eastbound departure from IAD initially heads southeast, positioning right-side passengers to see the city's urban grid and water features as the aircraft gains altitude. Notable sights include: Potomac River, Washington D.C. urban area, Chesapeake Bay (distant), Blue Ridge Mountains (far western horizon).

When landing at Juan Santamaria International (SJO), sit on the Left side for the best views. Left side provides views of the Central Valley and approaching terrain during descent into SJO. Typical westbound approaches to San Jose descend over the Pacific-facing slopes, and left-side seats capture the valley floor, agricultural areas, and the surrounding volcanic highlands that frame the approach corridor. Notable sights include: Central Valley of Costa Rica, Poás Volcano region, Barva Volcano, San José urban area.

The flight from Washington Dulles International (IAD) to Juan Santamaria International (SJO) takes Approximately 5 hours 15 minutes.

Gulf of Mexico (crossing over open water for roughly 2.5 hours), Yucatan Peninsula (limestone platform with cenotes visible at altitude), Caribbean coast of Mexico and Belize, Guatemalan highlands (Maya Mountains visible as distant ridges), Caribbean Sea approach to Central America, and the transition from lowland rainforest to Costa Rica's interior volcanic plateau
