A little headhunting update from the colonies:
Pilots With Part 121 Experience : EnvoyAir
Envoy rewards pilots with Part 121 experience : EnvoyAir
There is movement from one regional to another. For example, about 9% of attrition at Expressjet (the only regional for which I have data) in both 2014 (69) and 2015 (92) went to other regionals with Compass getting about a third of those numbers.
