Two data points.

1) I received an elite upgrade notification today (for ORD-LAX on Thursday); the email said "You've been upgraded from Chicago, IL (ORD - O'Hare) to Los Angeles, CA (LAX) on Thu., Mar. 8, 2012. Your new seat is XX" where XX was my old coach seat. Had to go to the website to select a new seat. If the system doesn't assign a new seat, the email should probably direct the recipient to go online to pick a seat, rather than having a glitchy sentence that still mentions the old seat.

2) I posted a several days ago about an Aeroplan business-class award ticket on UA metal where a couple of the segments are showing in coach rather than business now. That still hasn't rectified itself.
