United Dreamliner to Fly One-Off Domestic Route Over Thanksgiving

Update October 5, 2013: United has cancelled this one-off route, but there are other opportunities to get on this flight domestically.

United's 787 Dreamliner will fly a single roundtrip from Seattle to Houston over with perfect flight times for this Thanksgiving.

How can you get on the Dreamliner on a domestic flight for far less than an international flight?

There's currently only Standard (double-price) award space on the flight in both directions.

That means a roundtrip on a flat bed would set you back 100k United miles.
