I'm sure somebody has asked a similar question, but I did not find the answer by reading the Wiki's, the AA Lounge Access pages or by scrolling through these posts.
I am PLT flying MDE-MIA-DFW-TUS all on the same day. It's all same ticket, all AA-marketed/operated. I know I get FL access at MIA. But, I am not 100% sure that I get FL and/or AC access at DFW, so that is the question.
The AA FL access page section for AA elites only says "connecting to international flights," and the AC access page just says,"on international flights." I am pretty sure that those two statements would include the 2nd domestic connection on the same day, but I would like to confirm.
