This is something to discuss in the other thread. If I recall, Premium Economy started out in a separate program that has now been integrated:
Discounts are offered on all First, Business, and Premium Economy class tickets with participating carriers, and are offered on refundable, restricted, and non-refundable fare types.
...but note that different fares may be available if you call, rather than rely on the website.
