Flying R from DFW to ORD in September. 4 people in our party, 2 have Pre-check, two don't. At this point, I have no idea which terminal we will be in. Today the flight is leaving from terminal D but the equipment is changing between now and then so I guess it is possible that we could end up back in terminal A.

I generally just go straight to the Pre-check line so I can't remember if I've ever used the Priority line before. Can you go through the Priority line and then go through either standard screening or Pre-check or does it dump you right into a standard screening lane? Time-wise, Priority might be as fast as Pre-check but it makes a difference having to pack for going through the standard screening line. Or I could send the 2 without Pre-check through the Priority line and continue to do things the way I always do.

Thanks
