On a related note, Southwest's crisis management team is currently scheduled to arrive at ORD at 12:39 AM CST. It'll show on flightaware.com as flight number 8804, leaving Dallas-Love at 11:00 PM. If there are any Chicago-area planespotters who want to brave the blizzard, this would be a good chance to get a rare shot of a Southwest plane at O'Hare.
I'm not familiar with the area, unfortunately I've never been to Chicago. That would indeed be interesting to see and fun under better circumstances. Was the original flight not scheduled to land in Chicago?
