Something to consider about Allegiant. As long as Maury Gallagher is at the helm you can never forget where Allegiant came from. It's why I left. This is a very long read and has 3 parts (links at the bottom of the page). I think it's a valid read for all pilots, especially those at Allegiant and considering it.
