Three terminals at Havana airport keep travellers well separated into categories. Terminal 3 is for foreign tourism. It is modern, clean and fairly efficient. The reviews in this page are referred to this terminal. Terminal 2 is for Cuban exiles visiting the island. It is small, generally overcrowded, not particularly clean (specially the restrooms) and even a bit chaotic. Lots of custom and immigration officers everywhere. Terminal one is for nationals. No words for this one.
