When you search AA by "Price and Schedule", it will be the column labeled "Economy Flexible".
To confirm this, select the flights/fares you want to price and click [Continue]. When you get to step 3, "Passengers", the top tab on the page will be titled "Your Itinerary". One of the columns is Cabin/Booking Code and this should say Economy/Y.
Don't forget the "Instant Upgrade" fare, which may be cheaper than Y. It will guarantee you a Business Class seat, and should have the same bonus miles.
