Sorry if I'm not posting this question in the right place? Does AA use O'Hare Terminal 3 for all flights, or does it use Terminal 5 for flights to and from CUN? I was that Terminal 5 is considered the "international terminal" but AA typically uses Terminal 3. We're flying from ICT to CUN through O'Hare and wondered if we would need to transfer between terminals. Also, looks like the only Priority Pass lounges are located in Terminal 5 so we'd like to take advantage of those if we can. We have 2-3 hour layovers both ways. Thanks for your help!
