SkiAdcock just called again. She's getting closer to Chicago. Has talked to UA while in the car and they still would not give her one of previously open F seats on the 1830 ORD-FRA (they're all gone now) because they were not part of award inventory. At this point she is not booked on anything and is hoping for a lot of luck when she arrives at ORD and gets to deal with this in person.
