Letiole: I think I'll leave that typo uncorrected.

It's also interesting to see how people's happiness effect just changes from what is old, and not necessarily what airlines are doing. This works both ways. Delta FF's are bad that they are losing systemwide upgrades, but, on the other hand, Delta is just being brought into line in this matter with other airlines (I am NOT defending Delta and realize that there are other factors that make Delta a bad program).
