my take, for the industry generally, nothing specific to SW, will be a bi/tri-furcation

1) FO wages will reflect supply >> demand
2) captain wages will be be strong
3) LCA wages will continue on par with the majors

FO's are really a renewable resource and the company is doing then a favor with every hour accrued. At the other end, LCA's are a precious commodity that command career wages. Captains are in-between
