Drawing a brainfart right now but I was perusing the Trip Coverage and came across a 3 day trip assigned to a reserve that had this in the notes section of the trip:

"WL ND FO DUE SICK/CVRG NYC 8041/28..RESERVE ONLY..NO
WHIS..NO GRES..CG"

My question is, if you have a WS or GS in and the trip meets your criteria, why are they able to deny that right off the bat and give it to a reserve? GS I understand, but not the WS part. Perhaps I'm suffering from sleep deprivation but I wasn't aware that they could do that.
