Sit on the Right side of the plane for the best views on flights from Seattle to Boise. Right-side seats win the full journey. Takeoff offers Mount Rainier and the Cascades, and the route southeast across Washington and into Idaho keeps the Blue Mountains and Wallowa Range visible on the right side during cruise. Landing on left is good, but the extended cruise-phase views favor the right.

During takeoff from Boeing Fld King Co International (BFI), sit on the Right side for the best views. BFI typically departs to the south or southeast.

Notable sights include: Mount Rainier (14,411 ft, ~60 miles southeast on horizon), Cascade Range foothills, Lake Washington, Puget Sound to the west.

When landing at Boise Air Terminal (BOI), sit on the Left side for the best views. Boise typically lands from the northwest on runways 10L/10R. Left-side seats provide the best view of the Boise foothills and the Boise River valley as you descend. The city's grid layout and the Owyhee Mountains to the south are visible on approach. Notable sights include: Boise foothills (directly north of city), Boise River valley and downtown grid, Owyhee Mountains (south), Treasure Valley agricultural plains.

The flight from Boeing Fld King Co International (BFI) to Boise Air Terminal (BOI) takes Approximately 1 hour 15 minutes.

The flight path crosses central Washington's high desert plateau. Notable features include the Columbia River (visible as a winding corridor of green vegetation), the Blue Mountains on the right (Oregon-Washington border region), and the transition from Cascade rain-shadow forest to sagebrush steppe. The Wallowa Valley and Wallowa Mountains (northeast Oregon) may be visible on the right during cruise if conditions are clear. Spokane lies well to the north and is not typically visible on this southeasterly routing.
