You can also select your flights and specific fare buckets by segment in matrix.itasoftware.com. Then use the copy option to paste the full URL into bookwithmatrix.com to build your trip and send you to aa.com. This has been a godsend on a few trips where I needed to book a specific fare bucket to be able to use certain types of upgrades.
