Sit on the Right side of the plane for the best views on flights from Philadelphia to San Francisco. The right side wins overall because the SFO arrival view of San Francisco Bay, the Bay Bridge, and the city skyline is one of the most spectacular urban approaches in the US. The left side has a good Philadelphia departure but the right side delivers more consistently across the full flight, also catching the Sierra Nevada on the right during the California crossing.

During takeoff from Philadelphia International (PHL), sit on the Left side for the best views. PHL typically departs westbound on runway 27L/27R, so the left (south) side gives you a clear view back over the Philadelphia skyline, the Delaware River, and the Ben Franklin Bridge as you climb out. The right side faces north toward the New Jersey suburbs with less to see. Notable sights include: Philadelphia city skyline, Delaware River, Ben Franklin Bridge, Philadelphia Navy Yard.

When landing at San Francisco International (SFO), sit on the Right side for the best views. SFO typically lands on runways 28L/28R approaching from the east over the Bay, so the right (north) side gives you a sustained view of the San Francisco Bay, the Bay Bridge, and the San Francisco peninsula as you descend. The left side looks south over the less scenic South Bay and San Jose sprawl. Notable sights include: San Francisco Bay, Bay Bridge, San Francisco city skyline, Marin Headlands.

The flight from Philadelphia International (PHL) to San Francisco International (SFO) takes Approximately 5 hours 30 minutes to 6 hours.

The flight path crosses the Appalachians over central Pennsylvania, then the flat Ohio and Indiana plains, Chicago and Lake Michigan visible to the north, the Mississippi River near Iowa, the Great Plains of Nebraska and Kansas, the Rocky Mountains over Colorado or Wyoming, the Great Basin desert of Nevada, and finally the Sierra Nevada before descending into the Central Valley and crossing the Coast Ranges into the Bay Area.
