Second, this weekend, management decided to hold four pilots at PSA indefinitely rather than allow them to begin a class at US Airways in March."

Flow through agreements will be violated as necessary to maintain staffing levels at regionals with training bubbles and new aircraft coming online. Expect to see much more of this in the future. They will never let those planes park due to staffing. That's bad business.
