Yeah I just got back from a multi city AA flight (MIA, DFW, LAX) and none of the places gave me a complimentary WiFi code since they said it's for the EXP or paying Admiral Club Members.
I feel like AA cuts the most corners with amenities at their lounges in comparison to the other Airline lounges. Even the food is very skimpy (cookies till 5 PM and then a salad tray).
