In the "this pricing makes no sense" category . . .

Looking at SFO-LAX next month, BE is priced just $4 less than regular economy ($55 vs. $59).

And in the related, "I can't believe how cheap this fare is" category . . . F is only $160, and the post purchase buy-up was offered for $89, meaning a total price of $148 for a paid F seat.
