Let's assume, for the second, that both the law and Delta rules state that you can't have animals on board the plane. Then, is it okay to treat this person as she says she was treated?

So she was treated incredibly badly, while trying to do something she was legally allowed to do, and within the airline's rules. An awful experience.
