Got an early (potential) Xmas gift from a good friend who is an EXP. MAD-DFW on DEC17 on 789. SWU applied, plenty of empty biz class seats available (according to the seat map which may not be an indicator) but SWU has not cleared.

What are the chances of clearing given this may not be such a popular route? If anyone could offer any insight, I would really appreciate it.
