Just as an addendum to current events, as Expressjet (technically Atlantic Southeast Airlines in this case) begins shedding an approximate handful of airplanes per month in Oct, 2017, a stream of experienced CRJ pilots will enter the job hunt. This will continue through the estimated sunset of Expressjet's DL flying in Nov, 2018. IIUC, the existing KATL, KDTW and KLGA bases will disappear with a small KDFW base remaining for some AA flying.
At this point, there's absolutely no way to predict where people will go or try to go. But what seems a reasonable notion is some will go to other regionals. It's not unreasonable to assume many were already trying to locate elsewhere; now they have to.
The last seniority list I saw for ASA was just over a year ago but is good enough for amateur soothsaying and fortune telling. There were ~1500 pilots with the top third having been there 15 years or more.
Make of that what you will.
And...just in case this isn't complicated enough:
