Suspect that will clear over the coming weeks. It's not a weekend flight so hopefully I'm not competing with the mileage runners out there on the promo that runs through June for that route.
Since you're on a SWU you'll clear into a different inventory bucket (A I think) and not T-100>0 Hour X inventory. One time I've had a SWU not clear on a domestic route. Turns out First class was sold out and there were no cancellations. Happens but I bet you do OK on this one, lots of time.
