Recently I flew to Brazil on AA flight 929, Miami to Sao Paulo. The flight flew over Cuba, the Caribbean Sea, Venezuela and then into Brazil. Once my flight left U.S. airspace would it be taken over by Cuban ATC or is there a regional ATC center for the entire Caribbean area? With all of the small island countries in the area it would seem be more efficient to have one centralized ATC system.
By the way flying over Cuba was pretty cool! I couldn't see Havana since we flew over the east side of the island but it was still a treat.
