WE will be flying out of ORD on 23rd May 2017, Chicago to Texas. Staying in hotel overnight to be near airport in morning. I saw pictures of nightmare lines from May 2016. I see on here that wait times show under 15 minutes? How can that be when it was 2-3 hrs a year ago? Have they fixed the issues that well? If so, bravo! Thanks for any inside scoop.
