There are a lot of "unfair" deals out there on anniversary dates. I kinda doubt they'll negotiate a carve out to fix a case for a handful of pilots. After the merger a guy hired after me at the same airline is almost 100 numbers more senior because of class assignment. Others transferred over from subsidiary divisions of Delta.

At the time we accepted the deal we were given and at our levels of seniority no one really gives two hoots about our anniversary dates. Further, fixing some of these issues sets a precedent that others might try to "me too" on.

Not that I'm against fixing a special case, I just don't see those who are not effected getting behind it and some would be jealous if your issue was fixed and theirs was not.
