Miami International Airport — Miami, United States

Miami International Airport (MIA) functions as the principal air bridge between the United States and Latin America, handling more international freight than any other American airport and ranking among the busiest for international passengers overall. American Airlines operates one of its largest hubs at MIA, using Miami's geography to anchor connections arriving from across the Americas with onward service throughout the US and to Europe. The airport's terminal complex, one of the largest in the country by number of gates, reflects decades of incremental expansion rather than a single unified design, giving it a sprawling, sometimes maze-like layout that long-time travelers navigate with the help of an internal people-mover system called the MIA Mover. Miami's broader identity as a hub for Latin American commerce, culture, and finance is deeply intertwined with the airport's role, and Spanish-language signage and services are integral to the terminal experience. Cargo operations remain a defining strength of MIA's business model.
