Guys from my (large) reserve unit are getting hired like clockwork by legacies and LCCs after 12-18 months at a regional. It's now part of my standard in-brief for new gains coming from AD. Multiple data points in the past few couple years.
Seeing the same thing from the Skywest perspective, ex-mil new hires not sticking around for too long. The company is willing to keep doing it to fill seats short-term, and in the hope that a few will stick around longer.
