Tread with great care? Lol...
As mentioned, for a once or twice occurance there is zero chance of anything "bad" happening. Over the course of a day in the airline industry folks will miss thousands of flights for one reason or another, and AA (or any other airline) is not going to micro analyze each case and try to determine whether the pax intentionally skipped a segment or not.
