Sit on the Right side of the plane for the best views on flights from San Jose to St. Louis. Right-side seats capture the most dramatic scenery: the volcanic peaks and Central Valley during departure are visually striking and unique to Costa Rica. While left-side landing views of the Mississippi River confluence are excellent, the takeoff views from the right side are more distinctive and memorable for most passengers.

During takeoff from Juan Santamaria International (SJO), sit on the Right side for the best views. Right-side seats offer the best views during climb-out from SJO. The aircraft departs westbound initially before turning north, giving right-side passengers direct views of the Central Valley and the volcanic peaks that define Costa Rica's geography. Notable sights include: Irazú Volcano (3,432 m, often snow-capped), Cartago Valley floor with agricultural patchwork, Reventazón River valley cutting through green terrain.

When landing at Lambert St Louis International (STL), sit on the Left side for the best views. Left-side seats provide superior views during the descent and approach into STL. Aircraft descend from the northeast and turn southwest for final approach, positioning left-side passengers to see the Mississippi River, the confluence with the Missouri River, and the St. Louis riverfront and Gateway Arch. Notable sights include: Mississippi River (wide, meandering, clearly visible), Missouri River confluence (distinct color contrast where rivers meet), Gateway Arch and downtown St. Louis skyline, Illinois bluffs on the eastern bank.

The flight from Juan Santamaria International (SJO) to Lambert St Louis International (STL) takes Approximately 4 hours 45 minutes to 5 hours 15 minutes.

The flight path crosses the Yucatan Peninsula (flat, low-lying, with cenotes and limestone terrain visible from altitude), then over the Gulf of Mexico, then across the southern United States. Notable midpoint landmarks include the Yucatan's distinctive flat topography, the Gulf coastline near the Campeche region, and eventually the transition to the Mississippi River valley system as the aircraft approaches the central United States. The terrain gradually rises from coastal lowlands to the Ozark Plateau region visible during descent into St. Louis.
