Seattle to San Francisco: which side of the plane?

Sun left by day, right in the evening.

It turns with the clock. On morning and midday departures the sun is mostly on the left; leave in the evening and it is mostly on the right. Find your departure time in the table.

Out of the window

What you can look for.

Out on the edge of San Francisco Bay.

Along the way

  • The Sierra Nevada, a granite wall along the edge of the desert on the left, in daylight
  • Mount Rainier, standing alone above the Cascades on the left, in daylight

Leaving Seattle

Puget Sound, its wooded islands and ferries, opens up as you climb away.

Arriving in San Francisco

A long final low over the water of the Bay, with the Bay Bridge, the city skyline and, on a clear day, the Golden Gate to the north.

Best from the right, because the busiest west-flow arrivals (Runways 28L/R) come in from the southeast, keeping the Bay and city to the north, on the right.

How this was worked out

The same engine as the app.

These answers come from the model Jet Window uses on your phone: the sun's position from the cabin's own horizon at cruise, sampled along the great-circle path, with the landmark and airport notes the app shows. This page has to assume a departure time and a flight time, and a real flight bends with winds, airways and the runway in use. Cloud is not modeled.

In the app, Jet Window works it out for your actual flight, at its real departure time, and tells you when to look.
