I would say that the good 91 jobs are hard to get for airline guys simply because they don't have the same network that someone already in 91 or 135 might have. It's not that they aren't hired just because they have a 121 background. It's just that the cp already has a stack of resumes from buddies of guys already working for him, guys that may have chatted him up at an fbo, got to know him at a past training event, etc.....the good 91 jobs really are all about who you know.
