Miami International Airport

Miami International is the United States' most international airport by any meaningful measure: 127 airlines serve 266 nonstop destinations on 661 routes, the highest route count of any U.S. airport and among the top five globally. Roughly 70% of all passengers travel internationally, a share unmatched by any peer in North America. The airport functions as the indispensable gateway between the Americas — more than half of all U.S.–Latin America and U.S.–Caribbean passenger traffic transits MIA, along with the largest share of U.S.–Latin America air cargo. American Airlines operates its fourth-largest hub here and its undisputed Latin American command post, with roughly 350 daily departures reaching from Buenos Aires to Bridgetown. The hub structure is supported by four parallel and crosswind runways, the longest at 13,016 ft (3,968 m), and three terminals — North, Central, and South — arranged in a horseshoe around the central core. Concourse D, American's home, stretches 1.2 miles (1.9 km) and is among the longest single airport concourses in the world. Beyond passengers, MIA is the largest U.S. airport for international freight, handling more than 2.5M tonnes annually and acting as the logistics anchor for perishable trade between Latin America and the rest of the country — cut flowers, fresh fruit, and seafood in particular. Elevation is just 8 ft (2 m) above sea level, which, combined with proximity to the tropical Atlantic, makes MIA one of the most weather-exposed major hubs in the U.S.; hurricane preparedness dictates much of its operational planning.
