There was one Mesa captain who I thought was a "Mesa Lifer", but nope, he got on with Atlas! Mesa has a large number of Captains who've been there for 2/3rds of my life, as Mesa is one of the oldest regionals that has been stable enough to allow for such a thing. You need to look at the younger pilots, which most are moving on first chance they get. And despite the flows of other regionals, we have pilots leaving for those same majors, without a flow. The theory that you must work at Envoy, Brownstreak, or Piedmont to get on with American is not really true. I think Delta has hired more people from Mesa than they have from Endevor. Asking flight attendants about pilots leaving? Only a handful of them stick around long enough to ever notice that.
