The airport is large and very noisy, like most airports. You can easily find electrical outlets.
The 2 terminals have catering areas with several stands and tables and seats available. A few restaurants too, but the choice is not very large.
There s a lack of quiet places to hang out while waiting for your flight, and nice shops.
The directions are generally unclear, but people are mostly friendly and cheerful.
If we offer to accompany you, you should expect to pay a small tip (propina) of 10 to 20 pesos, this is a very common practice. The same goes for suitcase carriers who have small metal shopping carts. It is sometimes very convenient to call on them, especially since they know the whole airport very well.
The exchange rate is very attractive at the airport, it is better to change your currency directly.
Courage and patience to those who will leave Mexico City by rental car and who will drive in the urban jungle
