Miami International served nearly 56 million passengers in 2024 and has been the busiest US gateway for international passengers since overtaking JFK in 2021 (Miami International Airport). It is American Airlines' Latin America hub, LATAM's and Avianca's key US station, and, less famously, a real Europe gateway.
Why Miami dominates Latin America
Geography and hubs. Miami is the closest large US airport to the Caribbean, Central America and northern South America, and American routes most of its Latin network through it. Add LATAM, Avianca, Copa, Aeroméxico and the Caribbean carriers and almost every capital in the hemisphere has a nonstop. Competition is strongest to the big markets: Bogotá, Lima, São Paulo, Mexico City, Buenos Aires, Santiago. See Miami to Bogotá, Miami to São Paulo and Miami to Lima.
For US travellers elsewhere, that makes Miami the natural connecting point for South America; the trade-off is that the connection often falls in the evening bank, with overnight flights south.
The Europe network
From the airport's airlines-and-destinations table (Miami International Airport): London (American, British Airways, Virgin Atlantic), Madrid (American, Iberia, Air Europa), Paris CDG (Air France), Barcelona and Milan (American), Rome (American, seasonal), Dublin (Aer Lingus, seasonal), Frankfurt (Condor, Lufthansa), Helsinki (Finnair, seasonal) and Lisbon (TAP). French Bee flies Miami–Paris Orly as a low-cost option (Orly Airport). Madrid, with three carriers, is usually the most competitive pair; see Miami to Madrid and Miami to London, and our Miami to Europe guide.
Fort Lauderdale as the alternative
Fort Lauderdale–Hollywood (FLL), 30 miles north, is the low-cost airport for the region: JetBlue, Spirit and Southwest have big operations, with Caribbean and Latin service and, in some seasons, low-cost transatlantic flights. Always search MIA and FLL together.
Terminals and connections
MIA is one continuous terminal in three zones: North (Concourse D, American and its partners), Central (E, F, G; a mix of domestic and international) and South (H, J; most foreign carriers). International arrivals clear customs in D (American) or J (most others). The Skytrain runs within Concourse D, which is long; allow time for gate changes at the far end. The MIA Mover connects the terminal to the Rental Car Center and the Miami Central Station for Metrorail and Tri-Rail.
When connecting through Miami makes sense
- You are flying to South America from anywhere in the US on American or a oneworld partner.
- You want a nonstop-quality schedule to a Caribbean island that your home airport reaches only seasonally.
- You are combining a Florida stop with an international trip.
It makes less sense for Europe from the Northeast or Midwest, where a nonstop or a New York connection is shorter.
Tips
- International check-in cutoffs at MIA are enforced; arrive three hours ahead for long-haul.
- Global Entry and Mobile Passport Control save real time on arrival; the J and D halls get long in the evening South America bank.
- Summer afternoons bring thunderstorms and ground stops; morning departures are more reliable.
- For fare timing, demand to Latin America peaks at Christmas, Easter and the northern summer; Europe peaks June–August. Anchor to the current fare on the route page and set a price alert.
