Don't go to Comair. They're not hiring anyway. If you're looking for a quick upgrade for the 121 PIC, and as much as it pains me to admit it, you'll have ot go to somewhere like Chataqua/Shuttle America or Mesa or one of those type outfits. The pay is horrible among other things at those places, but with your qualifications, they would hire you very quickly. I'm a 4 year regional FO at one of the "better regionals" and still have no PIC, but my pay is decent though. Just depends on which path you choose to go down.
hope this helps.
