JetBlue hires a wide range of people from very different backgrounds. In my expirence, the Cape Air guys are great to work with, and do a great job of adjusting to the bus/190.

As for regional FO's, they are only a small percentage of the total hiring. I would say, 121 CA, corporate, and military are currently the largest groups, followed by 121 SIC and Cape Air.

Hope this helps.
