Skywest is a business with all the business things like...*customers*.
Our customers decided to renew (buy) a smaller amount of flying than they had before.
Xpressjet is transitioning to a dual class fleet and even then they are hopeful that United will have to keep the 145 lift with new *profitable contracts*. Profitability is a business thing too.

Inc block hours have been shrinking yoy. United has selected other airlines to fly the 145. They sure aren't at skyw.
