I have literally checked every date over the past week including the latest dates available into August and the lowest one person senior roomette fare from Chi to Lax and return on the TE was $876. Booking way ahead doesn't guarantee you low bucket anymore. If anybody on this forum can find a $600 fare,I'll grab it!How far in advance are you looking? The closer you are to a travel date the less likely there will be a low bucket fare.
