Out of class? Not a chance...expect ORD...it used to be MKE but I think there are enough displacements to knock it down from most junior base (?) Recently as things have been filling in and slowing down, new-hires were even getting COS/DEN after just a month or so, then the likes of FAT and SLC soon thereafter.
Also, it's worth noting that SLC, DEN, and ORD are where the vast majority of system-wide reserves are placed...
