A separate but related issue that I noticed is with the dates of reward reservations. The web site says the reservation will be held until one date and the confirming email has a different (sooner) date. I just did this yesterday and the web site said the reservation will be held until midnight Feb 17 while the confirming email said midnight on the 15th. Of course the system cancels the reservation as per the confirming email with the sooner date. It happens consistently as I'm putting reservations on hold trying to get better flights than one I have booked. I keep screen snapshots just in case it becomes an issue in the future.
