I searched but didn't find anything on this so sorry if this is a duplicate thread.

I'm a CFI around 550TT/250ME and I am looking for ways to build my resume other than TT. I have the FCC restricted radiotelephone, a B.S. in applied math, and I will be taking the ATP written next week. Would the FEX or any other test, license, course, or anything of the like look better for the regional airlines?

It's seems pretty clear that TT ends up being the bottom line for whether you are considered for a position but I haven't found much on what else looks good on a resume. With the months it will take to get the remaining TT wondering what else I can do. Thanks for the input in advance.
