I haven't seen anyone point this out, but when you click on a domestic Domestic Deal on the front page, it now takes you to a "lowest fare calendar", showing you which day is the cheapest based on how many days you plan to travel. Pretty neat, no longer need to search for those deals.

To see, login to your AAdvantage account and below the flight search, click on a city pair sale to bring up the calendar. Sorry if this has been discussed.
