I was just booking a trip for the summer and run a seach on ITA and it came out cheaper than economy.
Confirmed this on Orbitz, too, just booked for the dates 18 June to 24 June.
According to ITA, booking class F, thus full credits in most of the programmes.
Enjoy while you can! I also have included the screenshot of Orbitz finalising screen at
