For example if I was traveling to Brazil when visas were required, and I flew BNA-DFW-GRU and the BNA gates agent checked my visa and let me board but at DFW, the agent said no go, wouldn't that be AA's responsibility to get me home? (BNA is random; I would watch as AA agents would look at my Argentinian sticker [about half the time] and let me go through - there was a BR sticker too)

Cheers
