This also occurred on Flight 1121 today. There were 7 open seats in first and Y was oversold by 8. Now Y is oversold only by 6 and only 5 seats left in first. Typically they assign all first seats but 1 by now. New trend? Only 90 minutes until take off / 60 until boarding.
None of the elites got the UG. There is one 1T in front of me.
