To clarify, AA will only let you jumpseat if you are a pilot for a legacy carrier, or work for fedex or ups. There were 2 or 3 other small cargo carriers that I cannot recall at this time. But other than that, AA will not let you jumpseat in the cabin. I have heard about people jumpseating internationally from outside the US to outside the US. Not from outside of the US back to the US. I jumpseat internationally to go home every week. I jumpseat home on CAL to avoid landing fees, and non rev back into the US.
