Don't disagree with any of the responses - note, I'm not expected to see where I am on the UG list until 24hrs out. Just wondering about the accuracy about the available seats in general - sounds like the consensus is that it only shows unassigned seats; fair enough.

More broadly - what's the point of showing this info >24hr out, anyway?

I'll do an anecdotal review of accuracy as I get closer to flight time for a trip to the bay beginning of March - 3/8 RDU-ATL-SFO - both legs are showing like 50+ seats available. Yes, I know this is still far out enough that there might be a lot of close in bookings. Obvious re: the "I Love Delta" thread I'm taking a DL connection to SF rather than the UA direct RDU-SFO; that'd be gross.
