Flying DFW-ORD-AUH this week and have a long layover in ORD. DFW to ORD in AA First, ORD to AUH in EY Business. I initially thought I could access AA lounge on the domestic terminals. But seems like Etihad Business class passengers do not have access to it. I am having a hard time finding the lounge options (free ones) for Etihad in T5. Are there multiple options? Can someone post their recent experience?

Thanks!
