Exactly. You have to ask yourself why the regular line pilot doesn't have access to this info at DAL. The only reasonable answer I can come up with is that it would cost the Co. money because more pilots would catch mistakes.

Here's another question, why doesn't DAL automate more of the trip construction process? If there are so many problems with illegally constructed rotations (most probably being honest mistakes by overworked schedulers) how about you automate it so it must follow the PWA. I think a major corporation like DAL could pull that off.
