Understand that most regionals are unionized as well adds another hurdle to the equation. I'm not pro or con to unions but at PDT, they tried offering a $5000 sign on bonus around 2007. What ended up happening is most first year FOs made more than a 2nd year FO. Union called foul play and the company stopped paying it. Sucked too when you were told in the interview and accepted the position you were gonna get it then during your first day of training, sorry, your union that doesn't even protect you till after being here a year took care of it.
