SFO to BOS: which side of the plane should you sit on?
San Francisco (SFO) to Boston (BOS) is a 4,341 km (2,697 mi), roughly 5h 36m eastbound flight. Here is where the sun sits along that path, computed with the same astronomy as our live calculator.
On most daytime SFO to BOS departures the sun favors the right side — sit on the left (an A seat) for shade.

What you’ll see on this flight
Views are pretty even, so the scenery doesn’t settle the seat choice. Go with the shade side.
This route doesn’t pick a clear views side. You can still get a solid window seat either way, so follow the shade side if that matters more to you.
Takeoff
On departure, the left side catches the best early view depending on the runway in use: the Golden Gate Bridge, Golden Gate, Alcatraz Island, and San Francisco slide by first. A couple of minutes later, San Jose appears on the right.
En route
- 9m in← LeftSacramento
About 9 minutes in, Sacramento sits off the left side. It’s a city view, not a dramatic one, but it breaks up the climb.
- 18m inRight →Sierra Nevada
At about 18 minutes, the Sierra Nevada is on the right. You see a long mountain line from a distance.
- 1h 12m in← LeftGreat Salt Lake
Around 72 minutes in, the Great Salt Lake is on the left. It reads as a broad pale patch against the land.
- 3h 56m in← LeftLake Michigan
About 4 hours 5 minutes in, Lake Michigan is on the left. It’s the kind of large water shape that fills a lot of the window.
- 4h 42m in← LeftToronto
Near 4 hours 42 minutes, Toronto is on the left. It comes through as a dense urban shape rather than a single landmark.
- 5h 16m inRight →Catskill Mountains
On descent, about 5 hours 16 minutes in, the Catskill Mountains sit on the right. They come in as a low mountain line rather than a close-up ridge.
Landing
On arrival, the right side gets Worcester and Lake Chaubunagungamaug first depending on the runway in use. Then Boston comes almost under the aircraft on the right, while Massachusetts Bay sits on the left as you drop in.
Sides and timings are computed from this route’s geometry. What you actually see depends on weather, air-traffic routing, and the runway in use on the day.
Frequently asked
Which side of the plane avoids the sun from SFO to BOS?
Across typical daytime departures, the sun predominantly hits the right side of the aircraft, so the left side stays shadier. Seat letters start at the left window, so choose an A seat.
Which side has the sunset views on SFO to BOS flights?
For sunset views, flip the advice: on evening departures the sun sits on the left side of this route, so that is the side with the show.
How long is the flight from SFO to BOS?
The great-circle distance is 4,341 km (2,697 mi), which works out to roughly 5h 36m in the air on this eastbound routing. Winds and routing move the real block time around that estimate.
Does the date or departure time change the answer?
Yes — that is why the table shows both. The sun's path shifts with the season, and a morning departure can put the glare on the opposite side compared to an evening one. For a specific flight, the calculator samples the sun along the whole route for your exact date and time.
Which side of the plane has better views on SFO to BOS?
Neither side clearly wins. Views are close enough that the seat choice comes down to shade.
What can I see after takeoff from SFO to BOS?
Early on, the left side gets the Golden Gate Bridge, Golden Gate, Alcatraz Island, and San Francisco. San Jose is on the right a couple of minutes later.
