That said, it has been almost 4 weeks and nada of the ORD-MEX-ORD flights hasn't posted
If the flight is AA flight number, you earn as though you were on AA metal (EQM/RDM - the whole bit). I cannot address how long it takes for the miles to post.
If, however, your flight was MX-coded... you will earn the applicable RDM miles, based on the chart here:

That said, that same chart says to allow up to 30 days for posting. I'd give it another week if you don't see anything in your account by then.
