Sit on the Right side of the plane for the best views on flights from Chicago to Santa Ana. The right side wins overall because the Pacific Ocean coastline and Catalina Island on approach to SNA are among the most visually striking arrivals in the US. While the left side has a good Chicago departure view, the right side also picks up views of the Mojave Desert, the San Gabriel Mountains near the California border, and the dramatic coastal arrival. The right side delivers more consistently across the full flight.

During takeoff from Chicago Ohare International (ORD), sit on the Left side for the best views. ORD departures heading southwest on runways 10L/10C/10R or westbound on 32L/32R typically give the left side a view over downtown Chicago and Lake Michigan's shoreline. As the aircraft turns southwest toward the route, the left side looks back toward the city grid and the lakefront, while the right side faces suburban sprawl with little of interest. Notable sights include: Downtown Chicago skyline, Lake Michigan shoreline, Chicago River corridor, O'Hare's massive runway complex receding behind.

When landing at John Wayne Arpt Orange Co (SNA), sit on the Right side for the best views. SNA sits in the Santa Ana basin with approaches typically from the northwest on runway 20R/20L, meaning the aircraft descends over Orange County heading southeast. The right side faces southwest toward the Pacific Ocean coastline — Newport Beach, Huntington Beach, and the coastline are clearly visible on approach. The left side looks inland toward the Santa Ana Mountains. Notable sights include: Pacific Ocean coastline at Newport Beach and Huntington Beach, Santa Ana Mountains to the east, Orange County urban grid, Catalina Island visible on the horizon on clear days.

The flight from Chicago Ohare International (ORD) to John Wayne Arpt Orange Co (SNA) takes Approximately 3 hours 45 minutes to 4 hours.

The flight tracks southwest over Iowa and Missouri, then across Kansas and the Oklahoma panhandle, crossing into New Mexico near Tucumcari. Over eastern New Mexico and Arizona the terrain shifts to high desert plateau — the Colorado Plateau and Painted Desert are visible below. The flight crosses the Mojave Desert in California before descending over the San Gabriel Valley and into Orange County. The Rocky Mountains are largely north of the direct routing but the southern Rockies and Sangre de Cristo range may be visible on the horizon from the left side over New Mexico.
