You've probably heard by now that the Skyway is re-opening in time for Thanksgiving travel. But the Skyway isn't the only travel route that's getting a test this holiday weekend. O'Hare will be experiencing its first major holiday season after flight limits were put into effect on November 1. (You may recall the news from last summer that the FAA was forcing O'Hare to reduce flights into the airport, because delays at O'Hare cause delays at other airports nationwide.) On the bright side, there's apparently already a noticeable improvement in O'Hare's on-time performance this month. You'll still probably want to bring that paperback book to pass the time, though; airline officials are still advising customers to arrive at the airport two hours before your flight.
