had a contract lawyer familiar with issues in airline mergers review my pea. He basically said the intent of the document is correct but in reality it wouldn't hold up in a merger that operated under a cba.

Sounds like pea's would have to be fought on an individual basis at which point he said "do you have the financial means to fight that battle? Probably not." Once again, intent is there but the pea doesn't hold water in a real fight. Also, he said they can allow you to hit the 5 year point agreed upon in your pea and just let your term expire and say goodbye. It would be easy and you would have zero recourse.
