I noticed the AA winter weather waiver for ORD on Friday night, so called in and changed my Sunday DCA-ORD-SFO to DCA-DFW-SFO. Good thing I did as the ORD-SFO segment was cancelled today. Think my timing was pretty good as both my DFW-SFO and the one behind it are both sold out (F0Y0). Could have still made it home on Sunday, but it would have been with flights into the evening. Did get the upgrade for the first segment but nothing there to upgrade into on the second segment (had cleared both on the original itinerary, my 13th and 14th domestic upgrades of 2015).
