There are several international terminals, so check in advance. As I understand it, certain airlines are linked to a certain terminal. The terminal from which we flew to Istanbul is small. After the inspection and duty-free, there is an area with a cafe, a lot of people and queues almost everywhere (Starbucks and burgers are the most popular). Nearby there is a mini-bazaar with Mexican souvenirs from magnets to silver.
A good airport, small, everything is logically located. The only thing that we did not understand why there is no customs control on departure, in order to put a stamp in the passport, we had to run around asking where this magic employee is, as a result, they just made a note of the departure date in the entry stamp.
