According to mgmt., they've all been transferred to the XJT non-rev ops spec, presumably to facilitate ferrying and other mx activities. No idea what the priority or timing is for getting them through formal conformance to be on the revenue ops spec. I heard that TSA had removed the extra FA jumpseat and the XJT approved config requires that, so attaining those and installing them was one of the tasks on the list of things to do. These days, I would think it's a pretty low priority. Not sure where these airframes are at the moment, but there are a lot of 145s parked at TYS (an XJT mx base for those not familiar).
