I book through
AAA also and generally for AAA there is a slightly different code. I have not had a problem the last 2 years applying it for the discount and the ticket upgrade. I usually save about an additional $200. Usually if I find the code on the DIS, I call my agent and she hasn't heard of it yet. This being said, I have never had a problem applying it. I have found with AAA it all depends on your agent. This is why I use one in NJ when I live in MI - I love my agent!
