SEA → BOI
Which side of the plane to sit from Seattle Tacoma International Airport (Seattle) to Boise Air Terminal/Gowen Field (Boise)?
Right Side of the Plane
The right side offers a world-class viewing experience of the major Cascadian volcanoes, specifically a breathtakingly close pass of Mount Rainier and views of the Mount St. Helens crater.
Mount Rainier
The star of the route; usually passed at a very close proximity, revealing deep glacial crevasses and rocky ridges.
Mount St. Helens
Clear views of the infamous horseshoe-shaped crater and the blast zone resulting from the 1980 eruption.
Mount Hood
Oregon's highest peak is often visible as a sharp, triangular silhouette on the southern horizon.
Columbia River
The flight crosses the massive waterway near the Tri-Cities area where it carves through the basalt landscape.
Snake River Plain
Dramatic views of the winding Snake River and rugged basalt canyons as you descend into the Boise Valley.
This is the 'volcano side'. Request a window seat behind the wing to ensure an unobstructed view of Mount Rainier. Morning flights are ideal as the sun illuminates the eastern and southern faces of the mountains.
Seattle Cityscape
Aerial views of downtown Seattle, the Space Needle, and Lake Washington shortly after takeoff from SEA.
Mount Adams
The second-highest peak in Washington state, featuring a broad, snow-capped profile visible to the east.
Yakima Valley
A bird's eye view of the lush agricultural patchwork of vineyards and apple orchards in central Washington.
Columbia Plateau
Observe the dramatic transition from the green evergreen forests to the golden, arid terrain of the inland northwest.
Sit on the left during afternoon flights to avoid the direct southern sun glare. This side provides an excellent perspective of the 'rain shadow' effect where the lush forests abruptly turn into high desert.
