(Part 141) Im currently working to get my CFI [have my Pvt, Inst, Mel, Com] and I'm just trying to find out which regional airline I should choose. I have very little knowledge on what to look for and what to watch out for, in the part 121 world. I looking for job security, industry standard livable life, upgrade times & how well employees get treated. Any type of help would be amazing as I know very little on terms & general knowledge of working for a 121 operater.
