Sit on the Right side of the plane for the best views on flights from Seattle to San Diego. Takeoff views of the Cascades and Mount Rainier from the right side outweigh landing views. The northbound leg offers more dramatic mountain scenery, and the Cascade Range is one of the most visually striking features on this route.

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. Right-side seats capture the Cascade Range rising dramatically to the east, and you'll see Lake Washington and the Seattle urban grid spreading south. Left side faces west over Puget Sound with less dramatic terrain. Notable sights include: Cascade Range (eastern horizon), Lake Washington (below and south), Seattle downtown skyline (south-southwest), Mount Rainier (distant southeastern horizon on clear days).

When landing at San Diego International Lindbergh Fld (SAN), sit on the Left side for the best views. San Diego approaches typically use runways 27L/27R (westbound) or occasionally 09L/09R. On westbound approaches, left seats face north and capture the San Diego Bay, downtown skyline, and the Coronado Peninsula. Right side faces inland over less distinctive terrain. Notable sights include: San Diego Bay (prominent water body with North Island Naval Base), Coronado Peninsula (distinctive sandy spit), downtown San Diego skyline (clustered high-rises), Point Loma (rocky headland to the south).

The flight from Boeing Fld King Co International (BFI) to San Diego International Lindbergh Fld (SAN) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

Over central California, you'll pass east of the Sierra Nevada range (visible on the right/east side during cruise), cross the Central Valley, and approach the Transverse Ranges near Los Angeles. The Pacific coastline becomes visible on the left as you descend toward San Diego. On clear days, the Channel Islands may be visible off the coast south of Los Angeles.
