Most of the stuff in the international flights don't speak English and are unable to answer questions. At the same it was hard to find information booths.
When it comes to connecting flights the system is quite inefficient. For every flight you need to get your luggage and check it back in. On top of that if you decide to fly with Aeromexico even if the flight is international you need to go to the domestic terminal. In order to take the train from terminal 1 to terminal 2 you need to provide a ticket which isn't possible if web check-in for the airline has failed and they don't have ticket counters in the current terminal. I was surprised how badly the airport is organized.
