Sounds similar to jetBlue. IMO all pax airlines other than the big 3 are going to face attrition issues as pilots leave for the big 3:

1. Retirements / movement up the list
2. Widebody fleets
3. Bases

That's not even mentioning pilot contract differences. We can get an awesome contract at AS but it won't stop the bleeding to the big 3 for those three reasons. Anyone below age 40 with less than 5 yrs here, the equation favors leaving.
