In the late 80's and early 90's, the regionals (we called them "the commuters") typically didn't look at anybody with less than an ATP and 2000 total time, and 500 multi-engine. I was the lowest time guy in my class in '91 with 2100 total time and 330 multi time, along with the ATP. This was for a Bae32 Jetstream class - 19 seats, 16,204 pound max gross takeoff weight airplane that AE operated under part 135 regs.
