Benito Juárez International Airport

Benito Juárez International is Latin America's busiest airport by passenger volume, handling roughly 45.3M travelers (2024) and serving as the primary hub of Aeroméxico (SkyTeam) and a major base for Viva Aerobus and Volaris. MEX sits inside the urban fabric of Mexico City at 7,316 ft (2,230 m) elevation — making it one of the highest-altitude major international airports in the world, with performance implications requiring longer runways and payload restrictions on hot-and-high departures, particularly for long-haul operations to Europe and Asia. Aeroméxico operates its global network from MEX with Boeing 787-8/9 long-haul service to Madrid, Paris, Amsterdam, London, Seoul, and Tokyo, plus dense domestic and regional Latin American coverage. American, Delta, United, Air Canada, Iberia, Air France, KLM, Lufthansa, British Airways, Turkish Airlines, and ANA all operate scheduled service, and MEX is a major U.S.-Mexico gateway tied to the largest origin-and-destination bilateral market in the Americas. The network reaches 105 destinations across 34 airlines, constrained by a single-airport footprint saturated for years at nearly 1M passenger movements per year above its designed capacity. Two closely spaced parallel runways of 12,966 ft (3,952 m) and 12,795 ft (3,900 m) — both requiring long takeoff rolls at altitude — limit MEX to dependent single-runway operations and drive chronic congestion. Two terminals (T1, opened 1954 and incrementally expanded; T2, opened 2007) are connected by the free Aerotrén monorail, airside-restricted to SkyTeam transfer passengers. The saturation led the federal government to open the new Felipe Ángeles International Airport (NLU) in 2022 as a relief facility, creating a multi-airport Mexico City system; MEX nonetheless retains the bulk of international and premium traffic.
