I have seen a number of flights posted as "not valid for earn". Given money has been paid and the points were at the time based on $ spend how is this justified. On one occassion early in the year I won a return fare but it still cost me as much as a discount fare in fees and taxes, money I parted with but no points on the portion I paid and more importantly no SC's although my butt was in the seat.
