Mexico City has three main airports: the most frequently used is AICM (Aeropuerto Internacional de la Ciudad de México) and the closest one, followed by AIFA (Aeropuerto Internacional Felipe Ángeles), and Toluca International Airport, the furthest away. You can to downtown or the venue from either of them. Each of the airports have authorized taxis to get to downtown Mexico City, which we recommend to use. Only the AICM airport has a metro connection at one the gates connecting the airport.
From AIFA, there is a train to the Buenavista metro station, which is easily accessible. From Toluca Airport, you can also take public transportation to the Metepec Tren-Interurbano (intercity train) station, and from there you can reach the Observatorio metro station.
