I am Plat and going out to DFW at 6:45 p.m. on Tuesday night (April 9). I am supposed to get my UG notice 5 days out (meaning tomorrow) but was shocked to see the UG confirmation email at 6:06 p.m. today, a full day early. There are still 12 seats open after I received my UG.
OTOH, there were 14 seats open on the morning of my ATL-SLC run two weeks ago and I didn't clear until I got to the gate. Sweated that one, for sure. Of course that was hub-to-hub so guess they were holding back for FCM.
