So I guess it's not possible to work for a Legacy carrier if you have never worked for a regional. Also I'm not sure if the statement about regional captains being people that couldn't hack it in the "real world" of aviation is factual or opinion. Are there guys that had to settle for the regional job for life because they couldn't get a job at the majors? Yup. But this doesn't really account for the majority. Sad that such narrow views exist.
I wonder if I can use that as an excuse next time I land on a taxi way or over fly my airport. "Gee Mr. FAA guy it's just an entry level job. I'm not a "real pilot". And the guy I work with is stuck here because he couldn't pass the interview process at the worlds best airline." I bet that will go over real well.
