Don't get me wrong. XJet is a good job for a regional airline. But look at it this way, the sh1t could hit the fan at ANY company no matter how much koolaide is passed around.
I don't know if you have PIC time or not. I'm assuming you do if you have the chance to go to JB. Or, you've got one heck of a reccomnedation. Of the 30 or so people I know from my last job that made it to JB, only one had no fixed wing turbine PIC time. He was way persistant and has a ton of PIC in helos and well as considerable combat expererience.
Look at it this way if things went downhill;
Would you rather the chance to be trained in a 50 seat RJ or a narrow body A320?
