As I said- "I guess it could happen with any carrier", I just didn't put the "anyplace". We had our flight canceled to SXM on AA, and they didn't bother to notify us, even after we had requested the update service to contact us by e-mail, text, and phone of any itinerary changes. They did not contact us. I just happened to check, and found the flight had been canceled. We were able to get another flight after calling AA. They did not automatically put us on another flight.
