Can't do it when few intend to stay for a career. The career regionals lose contracts and shrink while pilots flock to the newer airline with low pay scales that wins that flying. So long as career advancement is valued more than current compensation we will perpetually be played against each other. The only true solution is to bring the bulk of the flying back to the career airlines. That will take a significant effort by the unions at the career airlines and they have other things they'd prefer to negotiate for.
