Sit on the Left side of the plane for the best views on flights from Burbank to Seattle. The left side wins overall. While the right side has a good departure view of the San Gabriels, the left side delivers Mount Rainier on approach — one of the most iconic mountain views from any commercial flight in the US. During the flight itself, the left side also tracks closer to the Cascades through Oregon and Washington, offering views of volcanic peaks like Mount Shasta, Mount Jefferson, and Mount Adams as distant horizon features.

During takeoff from Burbank Glendale Pasadena (BUR), sit on the Right side for the best views. BUR typically departs eastward on runway 08, so the right (south) side gives you a clear view of the San Gabriel Mountains including Mount Wilson and the broader LA Basin sprawl. The left side faces north toward the Verdugo Mountains, which are lower and less dramatic. Notable sights include: San Gabriel Mountains, Mount Wilson, Griffith Park and Observatory area, downtown Los Angeles skyline to the southwest.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. SEA typically lands on runways 16L/16R heading south, meaning the left (east) side faces the Cascade Range with Mount Rainier dominating the view. This is one of the most spectacular approach views in the continental US, with Rainier visible from over 100 miles out. Notable sights include: Mount Rainier, Cascade Range, Lake Washington, Puget Sound.

The flight from Burbank Glendale Pasadena (BUR) to Seattle Tacoma International (SEA) takes Approximately 2 hours 30 minutes.

The flight tracks north up the Central Valley of California before crossing into Oregon. Mount Shasta is a prominent snow-capped volcanic cone visible from both sides around the California-Oregon border. Over Oregon, the Cascade Range runs parallel to the left side of the aircraft, with Crater Lake occasionally visible in clear conditions. Mount Jefferson and the Three Sisters volcanic group appear as snow-capped peaks on the left horizon over central Oregon. The Columbia River Gorge marks the Oregon-Washington border. Over Washington, Mount Adams and eventually Mount Rainier appear to the left as the aircraft descends toward Seattle.
