I don't think you will be able to go to Cuba if you are using a US plane or
are starting or ending your journey in the US.

There is a bit of politics involved, a 45 year grudge (something to do with
commie *******s) so you would need to adjust your itinerary.

The Cubans would love to have you, you just need to go there from a
country other than the USA. And you would need to go to a country other
than the USA on your first leg out of Cuba.
