"I often ask students and audiences a quirky question: "What is the capital of Latin America?" Of course, it is a region of a couple dozen sovereign countries and the colonies of several empires, so there is no real capital. But if there were, I assert, it would be MIA: Miami International Airport. Specifically, the American Airlines hub at MIA is the nexus of most of the hemisphere, as illustrated in this 2002 route map."
Miami being the "capital of Latin America", is something that I never, at all would have ever thought of, because, well, it isn't really in Latin America. But, seeing this chart of the MIA really makes me think, and Miami being the "capital" now makes a lot of sense. There are so many more flights from MIA connecting to places in Latin America than to other parts of the US, and even other parts of the world. It's a little crazy to think that this airport is the "hub" of Latin America.
