This lounge is not advertised at all. Just for the Platinum and Centurion amex members in Mexico(no many). I got my first platinum amex in Mexico. Is a hidden lounge, very few people visit it. That is why is my favorite at that airport. I got my Priority pass card that would get me into UAL, PC, Aeromexico, etc. But i always use my platinum amex to acces this one.
Any platinum memebr from any country can access.
