Question; On Friday morning, when they use same day flight change to move the MIA-EWR morning flight to an evening flight that is at the same time as their purchased ticket from MIA to DFW, what will happen? Will AA cancel one of the purchased tickets?
Assuming that they are not trying to change the final destination via SDC but rather the discrepancy is a typo, and further assuming that there is same-day change availability (it is not always available, even if seats are open), I doubt there will be a problem. While it is technically against the contract of carriage, once the tickets are under airport control, I do not think AA's systems are sophisticated enough to catch an SDC'd redundancy and cancel it (and hey, lord knows AA EXP desk agents have "protected" on plenty of flights that overlap with my originally scheduled but iffy flight) - I wouldn't expect it to be proactively cxld by AA; I'd be more worried about whether SDC space will be available.
