I am an ATP 9000hrs TT 4100 hrs PIC part 121 with no corporate time. EMB 145 B737 typed. What is the best way to find cororate job openings?
When you say corporate job I take it as Part 91. I don't look at Part 135 as a corporate job, they just use corporate jets. Unless you know someone you won't get into a GOOD Part 91 gig. Maybe if you offer to pay for a type rating you could get into a good Part 91 job right off the bat, but I actually don't know of a single Part 91 operator, around here anyway, that cares if pilots offer to pay for their own types. All the operators I know of pay for types and only interview you by in-house referral.
So, if you don't mind flying Part 135 (YIKES!) for a couple years, its pretty easy to find a job, especially if you're willing to pay for a type. Then you'll run into that person who will hook you up with a good Part 91 job. My first 91 job was after I was a co-pilot for 10 months. One of the charter customers decided to buy his own plane and took me from that job. Been 91 ever since.
There's a ton of BBJ's down here (South Florida), send resumes to everyone for starters. Sometimes its not "who you know", right place, right time works too.
