Look at it from Horizon's perspective...the airplanes are trashed now beyond belief. The chances of anyone besides a third world airline picking a few up is slim to none, much less all of them, so why not stick with the one domestic airline who will lease the whole lot?

There's also the rumor that there will be no more -300s because our maintenance department is too inept at maintaining the five that we have (everyone remember how spotless they were when they showed up?). So much so that United can't rely on them to schedule them anywhere.
