Sure it does. It shows people they can't buy $700 T fare tickets and upgrade for $500. DL can get people to pay $2500 for an M fare and use miles or a PMU/SWU to upgrade. It's called revenue integrity. It's why a Four Seasons doesn't drag people off the street with promises of $50 rooms that would otherwise go empty.
