Maybe. I'd bet that it would get you a job at a regional, but you'd have to compete with thousands of pilots with thousands of PIC time in a regional jet flying Part 121 for the job at the major. The 90 is a very small and light twin. Regional jets only weight about 50,000 lbs, which is not much to an airline. At least RJ's are jets and fly as airliners. I used my Cheyenne II & IV time to get to a regional to get 2000 Part 121 turbo prop and 5000 jet to get to the majors. Good luck.
