Sit on the Right side of the plane for the best views on flights from St. Louis to Milwaukee. Right-side seats capture the most visually distinctive features: the Mississippi River and St. Louis riverfront during takeoff, and then the gradual transition through central Illinois farmland and small towns. While Lake Michigan on the left during landing is striking, the right side's river views at departure and the broader landscape perspective throughout the flight provide more consistent scenic interest.

During takeoff from Lambert St Louis International (STL), sit on the Right side for the best views. Right-side seats offer views of the Mississippi River and the St. Louis riverfront as the aircraft climbs northward. The river's distinctive curve and the Gateway Arch area are visible during the initial climb-out before the aircraft turns northeast toward Milwaukee. Notable sights include: Mississippi River, Gateway Arch and downtown St. Louis riverfront, Illinois bluffs east of the river, urban sprawl of the St. Louis metropolitan area.

When landing at General Mitchell International (MKE), sit on the Left side for the best views. Left-side seats provide views of Lake Michigan and Milwaukee's waterfront during the descent and approach. The lake's expanse and the city's position along the shore are striking visual references as the aircraft descends from the west. Notable sights include: Lake Michigan, Milwaukee waterfront and downtown skyline, Milwaukee River mouth, Shorewood and North Shore residential areas along the lake.

The flight from Lambert St Louis International (STL) to General Mitchell International (MKE) takes Approximately 1 hour 15 minutes.

The flight path travels roughly north-northeast from St. Louis across central Illinois. Notable features include the Illinois River valley (visible around the 30-minute mark), scattered lakes and reservoirs in central Illinois, the transition from agricultural flatlands to slightly rolling terrain as the aircraft approaches Wisconsin, and the Kettle Moraine region's subtle topography visible during descent into Milwaukee. No major mountain ranges are visible on this route; the terrain remains predominantly flat to gently rolling throughout.
