I heard you are the person to talk to. I'm Looking to fly to Mexcio city at the end of this year from San Diego. There is info on customs from AOPA but any advice on customs and on the first port of entry would help too.

But my question on where to find information for where to land, parking, security etc. I find the websites are lacking on pilot information or contact emails phone numbers etc. 

I'm thinking Aeropuerto de Atizapán is the choice to go to CDMX, but also where do one find more info on central and south America. This trip is fine since I can carry enough fuel to fly there and back to US, but any longer trip I'll need to learn the how and where for refuel.
