I've been in that situation, and don't recall showing a passport to anyone. In fact, I'm sure I've just gone straight to the gate and boarded the domestic flight just like usual.

So wouldn't this all be different if he didn't get the dreaded 'this is not a boarding pass' thing from OLCI? in other words, the kid could have boarded, flown to ORD, and STILL not actually had the passport on him. It's just that his credentials hadn't been verified in the last few months.
