If US Airways changed its name to USair, would the list still be binding?
Of course.
The best way to think of it is that the award is binding on the pilots. Changing agents or corporate transactions will not change that reality. Whoever represents the pilots, in whichever corporation those pilots are employed, will be obliged utilize that list, even when constructing a new integrated list with another pilot group.
Of course, there's nothing that says that the two groups can't just say "fine, we'll accept the Nic, BUT, the new list will be based on DOH, so it doesn't matter". After all, a list is what you say it is, and the company could care less.
Given the relative DOH of the USAPA guys and the UAL guys, this very well could be an avenue they take.
