For comparison, when I book flights out of SFO I usually try to choose a seat on the left side, since departures from either the 1s or 28s are by far the most common. On a 1L departure, the left side offers a view of SFO itself and aircraft taxiing to the 1s, before doing a counter-clockwise track around SFO if the flight turns south. (On a 1R departure, or one that heads straight east and over OAK, this is less important.) On the other hand, a seat on the right side of the plane can offer a view of San Francisco when departing from the 28s (assuming there isn't an immediate right turn...and probably when it's not after sunset), when the plane hugs the coast before turning east to cross the Golden Gate.
Don't suppose any frequent BOS fliers have a preference? If I've ever flown out of BOS at all, the last time was in the mid-2000s and even that was in a center seat within an AA widebody nowhere near a window. Also unsure which traffic flow (northeast or southwest) is more "common", though of course all of this could go out the window and I may end up with a big empty view of Atlantic ocean or immediate overcast clouds no matter which window side I end up with.
But any insight is appreciated.
