I'm not giving up hope yet. I've suspected that the past couple months have been an early experiment for CX revenue management to figure out exactly how many full fare Y+ seats they can realistically expect to sell. They did marketing surveys before they rolled it out, but asking people whether they would pay x amount for something is different from seeing whether they really do.

If they're starting to get a clearer idea on that, maybe they'll start being willing to offer more discounted fares.
