How many people went to XJT looking for a quick upgrade? I would almost bet that the last guy hired there will upgrade after the guy hired at Eagle that day. And Mesa? How long are they gonna be around?
Here's something else to think about. What good do you think PIC time at Colgan or Mesa, etc. is gonna do for you? Yeah you might upgrade in a year but you're not going to Southwest or UPS unless your Dad's there. If majors arent hiring at all- which might be the case with consolidation- you're gonna be stuck where you are for a long while no matter what.
Also you hurt the industry when you work for bottom-feeder airlines. You are actually hurting yourself in the long run.
There are 1200+/- FO's at Eagle. An FO hired around Nov/Dec 2006 is halfway up that list right now. An FO hired a year ago today is more than 1/3 up the list. Obviously there are factors like age 65 and divestiture which will slow the movement but realistically someone hired today will upgrade at Eagle in under 4 years.
