3.5 days from departure and I'm looking at 2 open in F for CHS-ATL and 8 open in F for ATL-LAX (the latter down from 17 a few days ago). On an H fare and I didn't clear at the 5-day window (seriously Delta, just take that "benefit" off the list at this point), so I called and applied a RUC. Showing as waitlisted for both legs, and CHS-ATL is listed as RP and ATL-LAX is listed as OP. Just a data point, not sure if it means anything.
