Mainline management really hasn't done anything yet to really combat this issue. There are many steps that still have yet to be taken before there is a true shortage.

1. offer bonuses
2. permanently increase pay
3. offer flow
4. ab initio
5. offer seniority numbers
6. fly regional jets at the mainline at regional rates(it's still permitted flying at lower rates even if flown by mainline pilots)
7. full blown section one scope recapture, and mainline pay rates for RJ flying.

Management hasn't even been through step one yet. Although, certain synergies saw management operate larger mainline aircraft in certain markets.
