Mexico City International Airport (IATA: MEX, ICAO: MMMX), officially known as Benito Juárez International Airport, is the primary international airport serving Mexico City, the capital of Mexico. Located approximately 5 km (3 miles) east of the city centre in the Venustiano Carranza district, MEX is the busiest airport in Mexico and one of the busiest in Latin America.
The airport is named after Benito Juárez, the former President of Mexico. It opened in 1952 and has since grown to become the main gateway to Mexico, serving as the primary hub for Aeroméxico, the country’s flag carrier. The airport sits at an elevation of 2,238 metres (7,342 feet), making it one of the highest major commercial airports in the world.
MEX operates two passenger terminals connected by the Aerotrén monorail and a free shuttle bus service. Terminal 1 is the larger and older terminal, handling most international carriers and some domestic flights. Terminal 2 opened in 2008 and serves as the primary hub for Aeroméxico and its SkyTeam partners, including Delta Air Lines, Copa Airlines, and LATAM.
In 2025, Mexico City International Airport served approximately 44.6 million passengers. The airport was recognized as the third most punctual large airport in the world in 2025 by Cirium, with an on-time performance rate of 86.55%. A major renovation project worth 8.5 billion Mexican pesos began in May 2025 and is scheduled for completion by the end of 2026, ahead of the 2026 FIFA World Cup.
