PDX → ONT
Which side of the plane to sit from Portland International Airport (Portland) to Ontario International Airport (Ontario)?
Left Side of the Plane
The left side provides a premier viewing experience of the Cascade Range's volcanic peaks immediately after takeoff and a stunning approach over the high desert and San Bernardino Mountains.
Mount Hood
Immediately after takeoff, witness Oregon's highest peak and its glacier-clad summit rising dramatically to the east.
The Cascade Peaks
Enjoy a parade of stratovolcanoes including Mount Jefferson and the Three Sisters as you track south along the spine of the range.
Crater Lake
Keep a keen eye out for the deep blue waters of the United States' deepest lake nestled within its massive caldera.
High Desert Transition
Watch the lush green forests of the Pacific Northwest transition into the arid, rugged landscapes of Eastern Oregon and Northern California.
Mojave Desert
As you begin your descent, the vast, sun-baked basins and dry lakes of the Mojave come into clear view.
San Bernardino Mountains
A spectacular close-up of the rugged peaks and canyons during the final approach into the Ontario basin.
Book a morning flight to have the sun behind you, illuminating the Cascade peaks with perfect clarity. If flying in winter, the snow cover on the volcanoes is breathtaking. The left side is essential for seeing Mount Hood shortly after departure from PDX.
Willamette Valley
View the patchwork of vineyards and farmland that defines Oregon's premier wine-growing region.
Mount Shasta
One of the most massive volcanoes in the world, its snow-capped bulk dominates the horizon for a significant portion of the flight.
Central Valley
Observe the vast agricultural grid of California's heartland, often seen through a hazy, sun-drenched lens.
Inland Empire
During the final descent, enjoy bird's-eye views of the sprawling urban layout and logistics hubs of Ontario and surrounding cities.
San Gabriel Mountains
The dramatic southern wall of the Transverse Ranges provides a rugged backdrop as you enter the Los Angeles basin.
The right side is ideal for afternoon flights to avoid the harsh glare of the eastern sun. You will get an excellent profile view of Mount Shasta. Watch for the coastal ranges in the far distance, which sometimes poke through the marine layer.
