Short...

The ALPA rules are the integration can not change a pilot's position relative to others on his/her original seniority list. Which means you will never be senior to those who were senior to you at LUAL but passed up work at LCAL.

Now one could ask the question, "what if the ISL process took longer and my LCAL position would be greater after the arbitrated ISL than my LUAL position would be?" Strangers things could happen, but I doubt that will ever be a player in this ISL.

The longer this goes the more complicated the ISL will be.
