While landing favors left, the takeoff view of the Cascade Range and Mount Rainier is more visually striking and sustained. The 90-minute flight path generally follows a south-southwest corridor where right-side seats maintain better views of the volcanic peaks that define this region's geography.
Flight Path
The flight path crosses the Cascade Range foothills and passes near Mount St. Helens (west of the direct route but sometimes visible on clear days), follows the I-5 corridor through the Willamette Valley, and descends toward Portland with views of the Columbia River gorge to the north. The terrain transitions from volcanic peaks to agricultural lowlands. On clear days, Mount Jefferson and the Three Sisters volcanoes may be visible to the southeast during cruise altitude.
