Mexico City International Airport, officially Aeropuerto Internacional Benito Juárez, handles over 50 million passengers annually and operates as the primary international gateway for Mexico. The airport designation is MEX under IATA codes. Two terminals stand 3 kilometers apart, connected by the Aerotren, an elevated shuttle that departs every four minutes during operational hours from 05:00 to 23:00. Terminal 1 opened in 1958 and underwent major expansion in 2007. Terminal 2 opened in November 2007 at a construction cost exceeding 800 million USD. Aeroméxico operates its primary hub from Terminal 2, while Terminal 1 hosts most foreign carriers including Delta, United, American, Air Canada, Lufthansa, Air France, and Iberia. The airport sits at 2,240 meters elevation within the Federal District boundaries, approximately 5 kilometers east of the Zócalo historic center.
International arrivals proceed through immigration where two queues separate Mexican nationals from foreign visitors. Immigration officers stamp passports and may ask purpose of visit, duration, and accommodation location. The Forma Migratoria Múltiple, a tourist permit valid for 180 days, was historically issued as a paper document but transitioned to electronic registration in 2010. Officers determine the granted stay duration, which can range from 7 to 180 days based on stated plans. The baggage claim area contains 24 carousels across both terminals. Customs operates under a traffic light system where each passenger presses a button after collecting luggage. A green light signals direct passage while red light triggers bag inspection. Agricultural products, quantities of alcohol exceeding 3 liters, and tobacco beyond 10 packs face restriction or duty.
Currency exchange counters operate in the arrivals hall but offer rates approximately 10 to 15 percent below those available at downtown casas de cambio. The airport contains 47 ATMs across both terminals. Banco Santander, BBVA, Citibanamex, and Banorte machines accept international cards. Withdrawal limits typically reach 7,000 to 10,000 pesos per transaction depending on the issuing bank. ATM screens offer English, Spanish, and occasionally French or German language options. The Mexican peso trades in denominations of 20, 50, 100, 200, 500, and 1,000 peso notes, with coins of 50 centavos and 1, 2, 5, 10, and 20 pesos. Exchange rates fluctuate daily but historically range from 18 to 21 pesos per US dollar during the 2020s.
SIM cards for Mexican mobile networks sell at kiosks operated by Telcel, AT&T Mexico, and Movistar in both terminal arrivals areas. Telcel maintains the most extensive national coverage, operating over 100,000 cell sites across 31 states. Prepaid tourist packages typically offer 2 to 10 gigabytes of data with 30-day validity, priced from 200 to 500 pesos. Registration requires passport presentation under telecommunications regulations enacted in 2021. The airport provides free WiFi through the network "WIFI-BAMX" without password requirement but with 60-minute session limits. Connection speed averages 5 to 15 megabits per second depending on terminal location and user load.
Ground transportation options from Terminal 1 include authorized taxi services, ride-sharing applications, metro access, and the Metrobús rapid transit line. Authorized taxis operate through a prepaid booth system where travelers purchase tickets based on zone destination. The Zócalo area falls within Zone 4, costing approximately 280 to 320 pesos depending on exact hotel address. These yellow and white taxis depart from designated ranks outside the arrivals exit. Uber, Didi, and Cabify serve the airport through pickup zones located on the departures level of each terminal, requiring travelers to ascend one floor from arrivals. Metro Line 5 Terminal Aérea station connects to Terminal 1 through a 400-meter outdoor walkway, operating from 05:00 to midnight on weekdays and 06:00 to midnight on weekends. The metro charges 5 pesos per journey regardless of distance. The Metrobús Line 4 gold route runs from Terminal 1 to downtown stations including Buenavista, requiring a rechargeable card purchased for 20 pesos plus fare load.
Terminal 2 lacks direct metro access, necessitating either the Aerotren transfer to Terminal 1 or immediate taxi or ride-share departure. The Aerotren operates free for ticketed passengers but charges 30 pesos for those without boarding passes. Journey time between terminals averages 7 to 10 minutes including waiting and boarding periods. Travelers continuing to Guadalajara, Monterrey, Cancún, or other domestic destinations often transfer between terminals, as domestic carriers including Volaris, Viva Aerobus, and Interjet historically operated from Terminal 1 while Aeroméxico domestic flights primarily use Terminal 2.
The drive from airport to Zócalo area hotels takes 25 to 90 minutes depending on traffic conditions. Morning rush hours from 07:00 to 10:00 and evening periods from 18:00 to 21:00 often extend journey times to 60 minutes or more. The airport lies east of the city center with primary access via Circuito Interior, Viaducto Miguel Alemán, and Eje Central Lázaro Cárdenas. Ride-share applications display upfront pricing typically ranging from 150 to 250 pesos for downtown destinations during non-surge periods. Surge pricing during peak hours or rain can multiply base fares by factors of 1.5 to 3.0.
Accommodation check-in times in Mexico City typically begin at 15:00, following international hotel industry standards. Early arrivals on overnight flights landing between 06:00 and 10:00 often face waits of several hours before room access. Many hotels in the historic center and Polanco district offer luggage storage for guests arriving before check-in, allowing immediate exploration. Hotels near the Zócalo including Hampton Inn, Gran Hotel Ciudad de México, and Downtown México concentrate within a 500-meter radius of the central plaza. The area contains 35 registered hotels offering approximately 3,200 rooms total. Polanco neighborhood hotels lie 6 kilometers northwest of the Zócalo along Avenida Presidente Masaryk, the district's primary commercial street. Condesa and Roma neighborhoods position 4 to 5 kilometers west of the city center, connected by Avenida Insurgentes.
First-time visitors arriving in Mexico City encounter altitude effects from the 2,240-meter elevation. The reduced oxygen partial pressure at this altitude equals approximately 76 percent of sea level values. Symptoms including headache, fatigue, and mild shortness of breath during exertion commonly appear within 6 to 12 hours of arrival. Hydration assists acclimatization, with medical guidance suggesting 3 to 4 liters of water daily during the first 48 hours. Alcohol consumption exacerbates altitude effects. The body typically adapts within 2 to 3 days through increased red blood cell production and respiratory rate adjustment.
The airport operates 24 hours but experiences reduced service between 01:00 and 05:00 when many food vendors, currency exchanges, and some transportation options close. Overnight flights from European cities including Madrid, London, Paris, and Frankfurt typically land between 06:00 and 09:00. Westbound flights from these origins cross 6 to 8 time zones, requiring travelers to adjust sleep schedules. Flights from the US west coast including Los Angeles, San Francisco, and Seattle typically take 3.5 to 4.5 hours. US east coast routes from New York, Miami, and Atlanta range from 4 to 4.5 hours flying time.
Terminal 1 contains 26 gates in the international section and 26 domestic gates across seven concourses labeled A through G. Terminal 2 includes 22 gates in a more compact layout with international and domestic sections separated only by signage rather than physical distance. Both terminals contain Sanborns restaurant locations, a Mexican chain operating since 1903 that serves combination plates of enchiladas, rice, and beans for 120 to 180 pesos. American fast food franchises including McDonald's, Starbucks, Burger King, and Subway operate in both terminals with prices approximately 20 to 30 percent above street-level city locations.
Porters wearing official identification badges offer assistance with luggage throughout the arrivals area, with customary tips ranging from 20 to 50 pesos per bag depending on distance carried. Some travelers report unsolicited porter approaches that can feel aggressive, particularly from individuals without official airport identification. The authorized porters wear red vests with "ASUR" or airport operator identification clearly visible.
Tourist information booths operated by the Mexico City Ministry of Tourism appear in both terminal arrivals halls, staffed from 08:00 to 20:00 daily. Staff provide city maps, transportation guidance, and hotel recommendations without charge. The booths stock glossy brochures covering major attractions including Teotihuacán, Templo Mayor, National Museum of Anthropology, and Chapultepec Castle. Paper maps of the historic center show street grids with major landmarks labeled in Spanish and English.
Water from airport bathroom taps is treated municipal supply but most travelers prefer bottled water for drinking. Convenience stores throughout both terminals sell bottled water in 500-milliliter to 2-liter sizes for 15 to 40 pesos. Brands including Bonafont, Ciel, and Electropura dominate shelf space. The dry climate at Mexico City's elevation increases fluid loss through respiration compared to sea level environments.
Banking services including full-service branches of Citibanamex operate landside in Terminal 1, offering wire transfers, account services, and enhanced exchange rates compared to the arrival hall counters. The branch maintains hours from 09:00 to 16:00 Monday through Friday. International transfer services through Western Union and MoneyGram operate from dedicated counters in both terminals.
The Metrobús Line 4 stations serving the airport include Terminal Aérea 1 and Terminal Aérea 2, though only the Terminal 1 station sees regular use due to the Aerotren connection requirement for Terminal 2 passengers. The Metrobús uses articulated buses running in dedicated center-lane corridors, achieving average speeds of 25 to 30 kilometers per hour compared to 15 to 20 for regular traffic. Travel time from Terminal 1 to Buenavista station near the historic center requires approximately 25 to 35 minutes with stops at 15 intermediate stations.
Mexico City operates 12 metro lines covering 226 kilometers with 195 stations, making it the largest metro system in Latin America by track length. Line 5, accessible from Terminal 1, runs north-south through the city with connections to Line 1 at Pantitlán station where many international flights terminate their metro journey to transfer toward downtown. The metro trains run on rubber tires rather than steel wheels, a design choice made in 1967 to reduce vibration impact on buildings constructed on the city's soft lake-bed geology. The system carries approximately 4.5 million passengers daily on weekdays.
Travelers continuing beyond Mexico City to other Mexican destinations often purchase domestic flight connections scheduled 2 to 3 hours after international arrival, allowing time for immigration, customs, and terminal transfer. Domestic carriers operate extensive route networks from Mexico City to Guadalajara (60 flights daily), Monterrey (55 daily), Cancún (45 daily), and smaller cities throughout the 31 states. Domestic ticket prices vary significantly based on booking timing and carrier, with advance purchase economy fares to Guadalajara ranging from 800 to 2,500 pesos while walk-up same-day tickets can reach 4,000 to 6,000 pesos.
The first meal upon arrival often occurs in the arrival terminal or during ground transportation to accommodation. Tortas, Mexican sandwiches constructed on bolillo or telera bread rolls, appear on most airport restaurant menus for 80 to 140 pesos. Fillings include milanesa (breaded cutlet), jamón (ham), or cochinita pibil (slow-roasted pork). Tacos al pastor, featuring spit-roasted pork with pineapple, sell at airport locations for 25 to 35 pesos each, with typical consumption of 3 to 4 tacos per person constituting a meal. Bottled juice brands including Jumex and Del Valle offer mango, guava, and tamarind flavors.
Airport rental car agencies including Hertz, Avis, Budget, Europcar, and National operate counters in both terminals with vehicle pickup from the multi-story parking structures. Mexico City's intense traffic, complex navigation, and restricted driving zones called "Hoy No Circula" that limit vehicle use based on license plate numbers make rental cars impractical for visitors staying primarily in the capital. The restriction program prohibits vehicles from operating one weekday per week based on the final digit of their license plate, designed to reduce air pollution and congestion. Rental agreements typically cost 500 to 1,500 pesos daily depending on vehicle class, with mandatory insurance adding 300 to 600 pesos per day.
The airport's elevation and the surrounding Mexico City basin create air quality conditions that vary by season. November through May constitutes the dry season with clearer visibility, while June through October brings afternoon thunderstorms and improved air clarity. Pollution levels measured by the Sistema de Monitoreo Atmosférico register higher concentrations during winter months when temperature inversions trap exhaust and particulate matter in the basin. The surrounding mountain ranges including the Sierra Nevada to the east and Sierra de las Cruces to the west limit air circulation.
Tourist arrivals in Mexico City peak during three annual periods: Christmas and New Year from December 20 to January 5, Easter week (Semana Santa) which varies between late March and late April, and Day of the Dead from October 31 to November 2. Hotel rates in the historic center during peak periods reach 2,500 to 4,500 pesos nightly for mid-range properties compared to 1,200 to 2,200 pesos during low season months of May, June, and September. Airport passenger volume increases approximately 35 percent during December compared to February, the slowest month.
The airport's Terminal 2 construction in 2007 did not fully alleviate capacity constraints, leading to planning for a new Mexico City International Airport at a site in Texcoco municipality. Construction began in 2015 with an estimated cost of 13 billion USD, but the project was cancelled in 2018 following a national referendum. Instead, the government converted the Santa Lucía Air Force Base, 40 kilometers north of the city, into Felipe Ángeles International Airport, which opened for commercial service in March 2022. This secondary airport primarily serves domestic routes and some international cargo operations, offering an alternative for travelers willing to navigate the longer distance to downtown Mexico City.
Luggage carts in both terminals require 20-peso coins for release from their locked bays, though recent installations accept both coins and contactless payment cards. The carts use a deposit-return system where coin insertion releases the cart and coin return occurs upon docking at another cart bay. Travelers without coins can exchange bills at currency exchange counters or purchase small items at newsstands to obtain change.
The airport's position within Mexico City proper rather than in a distant suburb means surrounding neighborhoods press close to the perimeter fences. The working-class colonias of Moctezuma, Aeronáutica Civil, and Federal create a dense urban fabric visible during landing approaches. Aircraft on westbound approaches pass over Chapultepec Park and its surrounding districts before turning east for landing, while eastbound approaches cross the drained Lake Texcoco zone and its flat expanse of former lake bed.
Power outlets in the terminals use Type A and Type B sockets, the same standard as the United States and Canada, with voltage of 127 volts at 60 Hz. European and British travelers require plug adapters, sold at electronics stores in the terminals for 150 to 300 pesos. USB charging stations appear throughout gate areas in both terminals, though occupancy rates often reach 100 percent during peak boarding periods.
Smoking is prohibited throughout both terminals under federal tobacco control regulations enacted in 2008. Designated smoking areas exist outside the terminal buildings beyond the departure and arrival exit doors. The regulations impose fines of 500 to 3,000 pesos for individuals caught smoking in prohibited areas, though enforcement varies.
Airport hotel options include the Hilton Mexico City Airport, directly connected to Terminal 1 by a covered walkway, and the NH Collection Mexico City Airport, adjacent to Terminal 2. Room rates at these properties range from 2,000 to 4,500 pesos depending on season and booking timing. These hotels serve travelers with early morning departures or those arriving late at night who prefer to begin sightseeing after rest rather than navigating transportation while fatigued.
Pharmacies operated by chains including Farmacias del Ahorro and Farmacias Similares appear in both terminals, selling over-the-counter medications, pain relievers, antihistamines, and basic medical supplies. Aspirin, ibuprofen, and acetaminophen brands familiar to North American travelers stock the shelves alongside Mexican generics at lower prices. A box of 20 ibuprofen 400mg tablets typically costs 35 to 65 pesos.
