Hmm I really dont' know what to say here except the lines went from one end of T1 (LH end) to the other end of T1 (connection to T2), formed a U around the security area and back towards the LH end of T1. How's that?

I was there at 9.45am for a 12.15pm ORD-HKG flight that my friend was taking. F/C/GS/1K line? if you could differentiate between any lines, I applaud you already. She checked in at 11.25am after I flagged down an agent I knew and begged her to check my friend in. We moved from the women's bathroom entrance to the men's bathroom entrance on level 1 in 2 hours.
