Sit on the Left side of the plane for the best views on flights from San Antonio to St. Louis. While takeoff favors the right side, the landing view of the Mississippi River confluence is geographically superior and more memorable. The river's dramatic meander and the Missouri confluence are iconic St. Louis landmarks visible only from the left side on standard approaches.

During takeoff from San Antonio International (SAT), sit on the Right side for the best views. SAT typically departs northbound (Runways 12L/12R or 30L/30R depending on wind). Right-side seats face west initially, giving views of the Texas Hill Country's rolling terrain and the Edwards Plateau escarpment. Left side shows the flat San Antonio sprawl and urban development. Notable sights include: Edwards Plateau (western horizon), San Antonio city grid, Medina River valley, Hill Country ridgelines.

When landing at Lambert St Louis International (STL), sit on the Left side for the best views. STL typically lands on Runways 30L/30R (eastbound approach) or 12L/12R (westbound). For the northbound flight path, expect eastbound approach (Runway 30). Left-side seats face north during descent, showing the Mississippi River's dramatic meander and the confluence with the Missouri River—the defining geographic feature of St. Louis. Right side shows less distinctive suburban sprawl. Notable sights include: Mississippi River meander, Missouri River confluence, Gateway Arch (downtown St. Louis), Illinois bluffs across the river.

The flight from San Antonio International (SAT) to Lambert St Louis International (STL) takes Approximately 2 hours 15 minutes.

The flight path crosses central Texas and southern Oklahoma, passing east of the Waco area and over the Red River (Texas-Oklahoma border). The Ouachita Mountains appear as a low, forested ridge in eastern Oklahoma/western Arkansas. The flight then crosses into Missouri, passing over the Ozark Plateau's rolling terrain before descending into the Mississippi River valley near St. Louis.
