Sit on the Left side of the plane for the best views on flights from Chicago to San Antonio. The left side delivers the Chicago skyline and Lake Michigan on departure, which is the most visually dramatic moment of the flight. The mid-flight view over flat Illinois, Missouri, and Oklahoma is similar on both sides, but the left side also picks up better angles on the Texas Hill Country transition as you approach San Antonio from the north.

During takeoff from Chicago Ohare International (ORD), sit on the Left side for the best views. ORD's most common departures head south or southwest on runways 10L/10C/10R or 28L/28R. A southbound or westbound departure puts the left side facing the Chicago skyline and Lake Michigan shoreline. The downtown Loop towers are clearly visible to the southeast during climb-out, with the lakefront stretching south toward Indiana. Notable sights include: Chicago Loop skyline, Lake Michigan shoreline, Midway Airport to the south, Illinois flatlands grid pattern.

When landing at San Antonio International (SAT), sit on the Right side for the best views. SAT's primary arrival runways are 13L/13R (southeast heading) or 31L/31R (northwest heading). On a flight arriving from the north, aircraft typically approach from the north on a southeast heading, putting the right side facing west and southwest toward downtown San Antonio and the Hill Country terrain rising to the northwest. The Edwards Plateau escarpment and the Balcones Fault Zone are visible as the flat plains give way to rolling limestone hills. Notable sights include: Downtown San Antonio skyline, Edwards Plateau escarpment (Balcones Escarpment), Medina Lake to the west, flat South Texas plains to the east.

The flight from Chicago Ohare International (ORD) to San Antonio International (SAT) takes Approximately 2 hours 45 minutes to 3 hours.

The flight tracks southwest over central Illinois farmland, crosses the Missouri Ozarks (low forested plateau, visible as darker rolling terrain), passes over Oklahoma's Cross Timbers region, then enters north Texas near the Dallas-Fort Worth metroplex visible to the east or directly below depending on routing, before crossing the Balcones Escarpment into the Texas Hill Country on descent into San Antonio.
