For people who are foreigners, it is necessary to consider that the airport in Cuba is very slow and delayed for all procedures. Therefore, in our personal experience, we arrived four hours in advance and almost left the flight for the long line that we had to do to pack our bags. That's why I suggest you go at least five hours in advance. Also consider that if you are very behind in the line and you are going to leave your flight, you let them skip the line, but it is a race against fate.
