Sit on the Left side of the plane for the best views on flights from St. Louis to Dallas-fort Worth. The left seat wins overall because the St. Louis departure delivers the most dramatic single moment of the flight — the Gateway Arch and Mississippi River directly below during climb-out. The right seat is better for the Dallas landing, but the STL departure view is the highlight of this route and tips the balance to the left side.

During takeoff from Lambert St Louis International (STL), sit on the Left side for the best views. Lambert typically departs southwest on runway 12L/30R or south on 06/24. A southwesterly departure puts the Mississippi River and downtown St. Louis on the left side, with the Gateway Arch clearly visible as you climb out over the river. The left seat also captures the confluence of the Missouri and Mississippi rivers to the northwest before the turn. Notable sights include: Gateway Arch and downtown St. Louis skyline, Mississippi River corridor, Missouri-Mississippi river confluence to the northwest, Cahokia Mounds site across the river in Illinois.

When landing at Dallas Fort Worth International (DFW), sit on the Right side for the best views. DFW arrivals from the northeast typically use runways 17C, 17L, or 17R, meaning the aircraft approaches from the north heading south. On the right side you get a clear view of downtown Dallas and the Dallas skyline as you descend, while the left side faces Fort Worth. The right seat also captures White Rock Lake and the distinctive Dallas urban grid on final approach. Notable sights include: Downtown Dallas skyline, White Rock Lake, Lake Ray Hubbard to the east, DFW airport layout and its distinctive oval terminal roads.

The flight from Lambert St Louis International (STL) to Dallas Fort Worth International (DFW) takes Approximately 1 hour 45 minutes to 2 hours.

The flight crosses the Ozark Plateau in southern Missouri and northern Arkansas, a broad upland of forested hills and river valleys visible as rolling terrain with the Lake of the Ozarks reservoir occasionally visible to the west. The route then crosses into Oklahoma and northeast Texas over the Red River valley, a wide flat agricultural corridor. The Red River itself may be visible as a reddish-brown meandering line marking the Oklahoma-Texas border. The terrain flattens progressively into the Texas Blackland Prairie as you approach DFW, with Lake Texoma visible to the left if routing takes you near the Oklahoma-Texas border.
