What I failed to mention was that this DHing crew had overnighted at the outstation with the intent of catching a DH later the next day. They went to the airport early morning to non-rev home, against what was their published schedule. When they arrived at the airport, they learned that a flight to ATL was delayed and the pax were rerouted through CVG. The flight had filled, and when they saw they weren't going to make it as non-revs, they called scheduling to demand their DH be changed, so they could be positive space.
Additionally, you don't see anything wrong (not contractually, I know the contract and I know its legal) with convincing scheduling to put you on reduced rest, then announcing to everyone that if they try to tag you you'll just call fatigued "just because I don't want to fly." This person was not fatigued at all. They just weren't in the mood to fly. It seems as if this silly profession was getting in the way of their personal lives. God forbid they actually have "responsibility" for their "job"
