Too many new guys and slightly "senior" FO's who think if they just accept this TA now they'll upgrade quicker.. Then they'll be making Cpt pay and sooner or later it'll be off to a legacy..

Then there are too many junior Cpt's who want to hold onto what they have for just a bit longer til they can high tail it to a Legacy....

Factor in senior Cpt's who get a bone or two thrown their way to keep them happy. Everyone knows they typically won't fall on a grenade for a first or second year FO..

Management plays regional guys like a fiddle...

Compare that to well paying legacy pilots....who typically aren't chasing upgrades.
