It doesn't say you can't go home for sure.

As far as "good faith", as the story was told, two attempts on a day off. didn't make it so he was removed from a certain amount of flying. He made it to that which was left. I fail to see how that's not good faith. He's not paid for the flying missed. He's not paid for time at the airport trying to commute on a DAY OFF. I don't see how he benefited from missing the original sign in time here in a way that's worth the effort put in.
