The most convenient airport to arrive at in Mexico City is Mexico City International Airport (Aeropuerto Internacional Benito Juárez - MEX). It is the main airport in the city, located about 20–30 minutes from most central areas, depending on traffic.
Official airport taxis are available just outside terminals 1 and 2 in the loading zone. Be sure to buy your ticket at the official counters. There are four major brands operating at the airport. Do not take a taxi from anyone offering taxi services outside the official areas.
Mexico City is about 7,350 feet (2,240 meters) above sea level! So if you're sensitive to high altitude, like Jonathan, and feel a little lightheaded, it's a good idea to bring something for altitude or motion sickness (like Dramamine or acetazolamide) and drink plenty of water (consult with your doctor first!!). Most people adjust quickly!
