Sit on the Left side of the plane for the best views on flights from Ontario to Phoenix. The left side wins overall. While the right side has the better takeoff view of Mt. Baldy, the left side tracks the Mojave-to-Sonoran Desert transition across the full flight and delivers the more dramatic landing sequence over Phoenix with South Mountain, Tempe Town Lake, and the city skyline all in view.

During takeoff from Ontario International (ONT), sit on the Right side for the best views. ONT typically departs east on runway 26R/08L. An eastbound departure on runway 08 puts the San Gabriel Mountains directly to the right (south-facing side), with Mount San Antonio (Mt. Baldy) prominently visible as the aircraft climbs. The urban sprawl of the Inland Empire fills the left side with far less visual interest. Notable sights include: Mount San Antonio (Mt. Baldy) at 10,064 ft, San Gabriel Mountains ridgeline, Chino Hills to the south, Ontario city grid below.

When landing at Phoenix Sky Harbor International (PHX), sit on the Left side for the best views. PHX typically lands westbound on runway 26 or 25L/R, approaching from the east over the Valley. The left (south) side gives a clear view of South Mountain Park, the downtown Phoenix skyline, and Tempe Town Lake as the aircraft descends over the metro area. The right side faces north toward the less dramatic suburban sprawl. Notable sights include: South Mountain Park, downtown Phoenix skyline, Tempe Town Lake, Camelback Mountain.

The flight from Ontario International (ONT) to Phoenix Sky Harbor International (PHX) takes Approximately 55 to 65 minutes.

The flight crosses the eastern Mojave Desert and then the lower Colorado Desert, passing over the Blythe area near the Colorado River. The terrain is flat and arid with dry washes and alluvial fans visible from altitude. Approaching Phoenix, the White Tank Mountains appear to the northwest and the Estrella Mountains to the southwest, framing the western edge of the Phoenix metro basin.
