Happened to a squadron mate. He had already used the PB days on trips, so they went back and took all the pay from that. He only found out because he noticed his check was short and looked into it. He called scheduling then CPO, not sure where it sits right now. They said they audited all of last year and I'm guessing they're saying he isn't owed the PRs. It's quite amazing how much they appear to be going out of their way to anger the pilot group even more.
