Yeah, I'd like to see more UA LAX-BOS non-stops just to get more PQM, since for the next couple years I'll be doing a lot of trips to BOS, but I've just started splitting my RTs across airlines. There are enough flights total across multiple airlines that it's not so bad.
And the OPs seat map looks like what SeatGuru calls the 739 v3.
I'd actually consider booking it if the flight was within a week, because a bunch of E+ are going to empty as people upgrade into the empty F seats. You might also get a reasonable F buyup offer. This far out I'd probably hesitate because the F seats could fill enough that little or no E+ empties (though I've been lucky in virtually always getting an E+ seat, even as a silver)
