I'm going Basic Economy. (I know, I know...but I'll only have a carryon and even after paying to seat select I'm saving enough to make it worth it.) Anyway, at first I was getting the seat map by going in through "My Trips," which means I'd show up as BE, so I thought maybe the blocking was a sneaky way of keeping BE families of four from sitting together. But I see the same thing even when looking at the seat map when just doing a flight search, and even for other days.

Obviously, I don't actually want to sit in a middle seat, but I'm just curious as to why they'd do this. Any ideas? Surely they can't be trying to keep the center section from being too crowded, can they?
