It could be that AS feels the flight will benefit from greater connectivity at PDX during the slowest period of business travel, but is otherwise content to keep the flight at 6:00 AM on a route that can usually rely more heavily on PDX originating traffic. It is one of the only flights AS is keeping before 7:00 AM at PDX with its banked hub structure.
