This may or not be related... and this is solely speculation.
On USAviation, there's stories floating around that 3/3 is supposed to be THE day that SHARES takes over all rez for US. One GA told a FFOCUS member that if he were smart, he'd not fly on 3/3.
Could this be the reason people aren't finding F availability?
Is this only for HP flights (i.e. SHARES/West), US flights (SABRE/East) or both??
