I started off chucking bags for NWA way back in the day... ok it was only 4-5 years ago but it seems like a lifetime. I just recently helped a guy I used to chuck bags with get a job with my current employer and he is probably the lowest time dude in the class. It can't hurt your chances plus if you can seamlessly go from chucking bags to flying you might be able to keep your seniority number for non rev travel... which would be nice.
