Yes, they did get the union as did AirLog prior to that. They start at around 42K (+ or -). Don't have the scales but, if you want to snoop around, try justhelicopters.com and the forum on that sight. (don't get caught up in all the whining and you'll get some straight stories)
By the way, PHI just announced their sale to some investor out of HOU so, it's hard to say what's going to happen in Lafayette.
If I were to start over in the GOM, I'd try my best to start with ERA out of Lake Charles, La. first. They don't have a union but do have a reputation for being OK without one. Real class act for the GOM (Plus they don't operate singles).
Good luck my friend.
