JS, my first thoughts are to your son. How is he doing now? I hope he isn't afraid to fly because of that woman's attack on him. And yes, I see it as an attack as she couldn't leave any quicker once she caused a computer to fall on his head. While I don't know what Delta's responsibility's are, I'm sure your attorney will. Plus, as some have said, Delta knows who that woman is. I wonder if a FA saw what she did. Or other witnesses?
Again, I hope your little boy is getting better.
