The three of us just went through security at O'Hare. I put my bag of liquids in a bin. Mr_go forgot to take his ziploc bag out of his rollaboard, and no one said a word. Allie_go forgot to take hers out of her backpack--her bag got pulled for a search and she was told the liquids should have been put in a bin. I think it all depends on the screener.

BTW, no lines at security (T1) at 1:30pm on one of the busiest travel days of the year.
