Yes, pilots can be more selective for sure. Pilots became more selective in the late 90's early 2000s when many regional companies offered pay for training. Comair, ACA, ConEx, CommutAir all these were pay for training companies. Once the pilot pool slowed nobody went to those thus they had to drop that practice. Seems to me that what Envoy is offering isn't something bad is it?

When someone selects a regional they usually look at Bases, Contract, Upgrade Time and lastly now today a Flow Thru. Where is Envoy lacking compared to other Regionals operating the 175's? Are they not getting any pilots in class already? If that's the case then AAG will up the ante don't worry.
American will make sure Envoy succeeds. Believe me there will be a more the a few contract carriers close there doors before Envoy.
