I'd bet 50% of regional pilots hired in the last year don't a have a degree. What that means, I don't know.

With schools like AllATP's advertising 2 years from zero time to E175 right seat it's no wonder why the overall level of maturity has dropped. A regional airline job has become really easy to get. People who can't hack a 4 year school are dropping out and going to a pilot mill, flying around 76 seaters with no interview.
