Quick question. I plan on doing a couple of these MR in August on the red-eye to ORD and hopefully be back at LAX by 9am the following morning. Quick question: Do I have to pass through TSA security at ORD in order to check-in to the my return flight, or do I just do an online check-in before departing LAX and after I disembark the plane at ORD just walk over to the gate of departure.
