I am going to try to book a revenue flight ex-MWH before the route ends... PM me if you're a SEA UA FTer and care to join.
EDIT: Doesn't look like fares ex-MWH are very nice ($472 to LAS) so I might just do a SEA-MWH-SEA turn on a Sunday for cheap.
EDIT 2: Flying 4/18 (Sunday) if anyone cares to join, UA6833-UA5815. Goodbye milkrun...
