It cleans it up.

Not sure exactly what it does, but it can help fix broken PNRs. I had to do it for paid and award tickets that had numerous changes, both from my actions and AA's. Any regular customer service reps should be able to do it, but might balk when they see it is a RTW. RTW desk might have shorter wait times due to the weather issues though.
