Not sure what's going on here.

This past weekend, pricing for SFO-BOS and vv suddenly jumped up: before when I was looking, it was in the $150-200 range for cheapest flights (across the board on dates and times). A few days ago, all dates in the future became $334 at the cheapest. Any idea what happened there? I thought this might have something to do with the recent software/schedule loads, but its persisted past that.

(Just to be clear, it ended up not mattering for me, since SJC-BOS is still at the lower price - just surprised that it hasn't come down at all, even for multiple months out! I understand a few days getting a bit more expensive, but this is pretty across the board)
