That is using SDC. What I am saying is that I’ve had no problem going to the agent and simply asking to be put on earlier flight - when on the same PNR. Now maybe that is because I am EXP? Maybe AA has changed it recently (but as recently as January I did it at ORD, from LHR). Done this at least half a dozen times in the last 5 or 6 years. I know AA made changes to SDC, but that’s not what I’m talking about. Just ask, worst they can say is No.
