Short of having legal constraints put on P2F schemes, there are only a few directions we can go. The professional pilot would be the one declines to work due fatigue. But the word profession also implies some reward for the service. However, there might be a way out. You can't really file an MOR/ASR when you reported unfit for duty because that would be admitting to criminal act. So the only sensible thing to do would be to file under the CHIRP scheme. These guys are legit and short of another smoking hole in the ground incident like Colgan 3407, there is little else available. After all, the airlines won't be doing anything. Seat 0F is a major profit centre.
