My Mexican passport expires in February. Will it be possible to go to Cuba or 100 percent do I need to renew it and have it valid for 6 months before traveling?

I'm not very sure but I think you can travel with him as well as before it expires.

no. I am Mexican. The problem is that they told me that if my passport is not valid for at least 6 months, they will not let me fly to Cuba. As I understand it, the Cuban authorities will have no problem once I am on the island, but the problem will be that the airline will not let me embroider a passport that is only valid for 4 months. If anyone knows of a way that I can go without renewing I would appreciate it.

Well, if you are Cuban, the Mexican passport does not help you to enter. If not, there is nothing disposed about previous months.
