I think OPs question stems from what recruiters are telling applicants at the interview. I assume from your response, those improvements have not been advertised to the pilot group...

I got the same non-specific statement at my interview. Based on the lack of any specific improvements cited, and judging by the relative happiness of the folks who post on here regarding scheduling (along with some other intangibles), I am considering other regionals over PDT. I would be happy to hear that I missed the mark in considering PDT, or that there are improvements coming that I, or any potential new hire, should consider while deciding where to call home for the next few years.
