A little confusing airport with two separate terminal buildings. Instructions are not very clear. If you have to switch terminals, there is not any kind of indication where you should head. I never found the tram which transports people between T1 and T2 and I had to take a bus, which cost 30 pesos. Personnel spoke good English, so I was able to get some instructions from them. 3 hours for a connectioin is a bare minimum for this airport, especially if you are coming to MEX airport for first time.
