The only thing to note is that the TATL inbound flights are sometimes held on the taxiway after landing due to terminal E congestion.
AA really do not like taking bags that were not already tagged here (even when on AA-AA). So should all be on one ticket, otherwise mentioned that is a chance have to take the bag to Terminal B for rechecking (I have asked many times so I could walk airside E-to-B, and declined every time). Other airports, like JFK, are much nicer about it. I have had 100% failure rate at BOS in rechecking with AA on separate tickets, I am glad others have had success.
