Sit on the Right side of the plane for the best views on flights from St. Louis to Pittsburgh (pennsylva). Right-side seats provide superior views for both segments: the Mississippi River meanders during climb-out and the Ohio River valley during the cruise phase as the flight tracks northeast across Indiana and Ohio. The landing view from the left is strong, but the extended right-side advantage during the longer cruise portion makes right the overall winner.

During takeoff from Lambert St Louis International (STL), sit on the Right side for the best views. Right-side seats capture the Mississippi River's distinctive meanders as the aircraft climbs northeast from STL. The river's oxbow bends are clearly visible from 5,000-15,000 feet and provide excellent geographic context for the early climb. Notable sights include: Mississippi River with characteristic meanders, Gateway Arch (small but identifiable on the riverfront), St. Louis urban grid spreading south and west, Illinois bluffs across the river to the east.

When landing at Pittsburgh International (PIT), sit on the Left side for the best views. Left-side seats offer views of the Allegheny River and Pittsburgh's distinctive three-river confluence as the aircraft descends into PIT. The river valleys and downtown skyline become increasingly visible on approach, especially during descent through 10,000-5,000 feet. Notable sights include: Allegheny River with its tight meanders, Monongahela River to the south, downtown Pittsburgh skyline at the confluence, Appalachian foothills rolling away to the southeast.

The flight from Lambert St Louis International (STL) to Pittsburgh International (PIT) takes Approximately 1 hour 20 minutes.

The flight path crosses central Indiana and western Ohio, passing east of Indianapolis. Notable features include the Wabash River valley (visible from altitude as a linear depression), the flat-to-gently-rolling terrain of the Ohio Valley, and the gradual transition from Midwestern plains to Appalachian foothills. The Ohio River itself may be visible during cruise if flying near its path, appearing as a thin silvery line winding through forested terrain. The landscape transitions from agricultural grid patterns in Indiana to increasingly forested, hilly terrain as the flight approaches Pennsylvania.
