Mexico City Transit Guide: How to Safely Use the Metro and Metrobús from MEX Airport

In March 2025, Mexico City’s government announced a MXN 1.2 billion (approximately HKD 510 million) renovation package for Metro Line 1, the city’s oldest and most heavily used line, which runs directly from the airport’s Terminal 1 station to key central districts like Cuauhtémoc and Paseo de la Reforma. This comes after a 2023 collision on Line 3 that killed one passenger and injured 106, and a 2021 elevated section collapse on Line 12 that killed 26. For Hong Kong travellers accustomed to the MTR’s 99.9% on-time rate and spotless stations, the Mexico City Metro presents a different proposition entirely. But here’s the thing: it works. With 12 lines, 195 stations, and an average fare of MXN 5 (HKD 2.10) — about 3% of what you’d pay for a single MTR trip from HKIA to Central — it remains one of the world’s cheapest urban rail systems. The question isn’t whether you should use it, but how to use it without incident. This guide covers the practical mechanics, the safety protocols that actually matter, and when to pay for a taxi instead.

The Metro: Lines, Stations, and the Airport Connection

Line 5 and Line 1 from MEX

The Metro connects to Mexico City International Airport (MEX) at two points: Terminal 1 (Station: Terminal Aérea, on Line 5) and Terminal 2 (Station: Pantitlán, where Line 5, Line 1, Line 9, and Line A converge). If you’re arriving at Terminal 1, follow the signs marked “Metro” past the taxi touts and down the ramp. The station entrance sits just outside the arrivals hall — you can’t miss the orange-and-white Metro logo. The walk from baggage claim to the platform takes about eight minutes. For Terminal 2, you’ll need to take the airport’s free Aerotrén shuttle to Terminal 1 first, then walk to Terminal Aérea station. Pantitlán is larger, busier, and more confusing; I’d only recommend it if you’re connecting directly to Line 1 for destinations west of the city centre.

Line 5 runs north-south through the eastern edge of the city. From Terminal Aérea, heading south (direction: Politécnico) takes you toward the city centre in about 15 minutes to La Raza station, where you can transfer to Line 3 for the historic centre. Heading north (direction: Pantitlán) loops you back toward Terminal 2. The trains run every 2-3 minutes during peak hours (7:00-9:30 AM and 5:00-8:00 PM, Monday to Friday) and every 5-6 minutes off-peak. Service ends at midnight — the last train leaves each terminal station at 12:00 AM sharp. Miss it and you’re looking at a HKD 150-200 Uber ride to central neighbourhoods like Roma or Condesa.

The MetroCard System and Fares

The Metro uses a contactless card called the Tarjeta de Movilidad Integrada (MI card), which costs MXN 15 (HKD 6.30) and can be topped up at any station’s ticket machines. These machines accept cash (MXN 20, 50, 100 notes) and some newer units take credit cards, though I’ve had more success with cash. A single journey costs MXN 5 (HKD 2.10) — yes, five pesos, unchanged since 2013 per the Sistema de Transporte Colectivo’s official fare schedule. You can also use the same card on the Metrobús, the city’s BRT system, and on the light rail. For a 48-hour stopover, loading MXN 50 (HKD 21) is more than enough for eight to ten trips. The card itself is valid for two years from purchase.

One practical note: the machines sometimes run out of cards, particularly at Pantitlán and Terminal Aérea on Sunday evenings. Keep MXN 15 in small notes for the card purchase, plus MXN 20 for your first top-up. The machines do not give change for notes larger than MXN 100.

The Metrobús: Faster, Safer, and More Comfortable

Line 4 and the Airport Express

The Metrobús is Mexico City’s bus rapid transit system, running in dedicated lanes on major avenues. For airport travellers, Line 4 is the relevant route: it runs from MEX’s Terminal 1 direct to the city centre, stopping at Buenavista station (near the historic centre) and San Lázaro (for connections to Line B of the Metro). The journey takes about 35 minutes from airport to Buenavista, versus 45-55 minutes on the Metro with a transfer. The Metrobús costs MXN 7 (HKD 2.95) per ride — still pocket change by Hong Kong standards.

The buses are modern, air-conditioned, and equipped with CCTV. They run every 4-5 minutes during the day and every 8-10 minutes after 9 PM. The last bus from Terminal 1 departs at 11:30 PM. Boarding is through the front door only; tap your MI card on the reader. The bus has designated priority seating for elderly passengers, pregnant women, and people with disabilities — these are clearly marked and locals generally respect them. Luggage space is limited to overhead racks that fit a standard carry-on; a full-size suitcase will need to sit on your lap or between your legs in the aisle. I’ve done it with a 22-inch roller bag and it’s manageable but tight.

Safety on the Metrobús

The Metrobús is statistically safer than the Metro. According to Mexico City’s Secretariat of Public Security’s 2024 crime statistics, there were 12 reported robberies per 100,000 passengers on the Metrobús versus 41 per 100,000 on the Metro. The dedicated lanes mean no traffic stops, and the buses have uniformed security personnel on board during peak hours. That said, pickpocketing remains the most common issue — keep your phone in your front pocket or a zipped inner compartment, not in your back pocket or an open jacket pocket. I’ve seen two attempts on the Metrobús Line 4, both involving a distraction technique where one person “accidentally” bumps into you while another reaches for your bag. The standard advice applies: keep your bag zipped and in front of your body, not slung behind you.

Safety Protocols That Actually Work

Peak Hours and Car Selection

The Metro’s peak hours are genuinely unpleasant. Between 7:30-9:00 AM and 6:00-8:00 PM, trains on Line 1 and Line 3 operate at 150-200% of their design capacity, according to a 2024 report by the Instituto de Ingeniería de la UNAM. That means you’ll be packed shoulder-to-shoulder, sometimes unable to move your arms. For women travellers, the Metro designates the first two cars of every train as “women-only” during peak hours — look for the pink signage on the platform. These cars are enforced by station staff and are noticeably less crowded. I’d recommend using them even if you’re a man travelling with a female companion; just stand in the adjacent car and meet at the destination platform.

If you must ride during peak hours, choose the middle cars of the train (cars 3-5 on a typical 9-car train). These are less crowded than the end cars, which fill up first because passengers board from the platform ends. Stand with your back against a pole or the wall, not in the middle of the carriage. Keep both hands free — don’t hold your phone in your hand. I’ve seen three phone snatches on the Metro, all involving someone grabbing the device as the doors close and jumping off at the last second.

Night Travel and Station Selection

The Metro closes at midnight, but safety degrades noticeably after 10 PM. According to the same 2024 UNAM report, 34% of all Metro robberies occur between 10 PM and midnight. If your flight arrives after 9 PM, take a taxi or Uber. The authorised airport taxi service (Transporte Terrestre) costs a flat MXN 200-250 (HKD 84-105) to central neighbourhoods, payable at the booth inside the arrivals hall before you exit. These are safe, regulated, and tracked. Uber from MEX to Roma Norte runs about MXN 180-220 (HKD 76-93) depending on surge pricing.

For Metrobús travel after 9 PM, stick to Line 4 (the airport route) and avoid lines that run through Iztapalapa or Ecatepec — these are the boroughs with the highest robbery rates, per the Secretariat of Public Security’s 2024 data. The Metrobús runs until 11:30 PM on most lines, but frequency drops to every 10-12 minutes after 10 PM.

When to Skip Public Transit Altogether

Connections to Other Airports

If you’re transiting through MEX but need to connect to Mexico City’s other airport, Felipe Ángeles International Airport (NLU), do not take the Metro. NLU opened in 2022 and is located 45 km north of the city centre in Zumpango. There is no direct Metro or Metrobús connection. The authorised shuttle service (operated by Mexibús and connecting via Line 1 of the suburban rail) takes 90-120 minutes and requires two transfers. A taxi from MEX to NLU costs MXN 600-800 (HKD 252-336) and takes 50-70 minutes depending on traffic. Budget at least three hours between flights.

Heavy Luggage and Mobility Constraints

The Metro has no escalators at 43 of its 195 stations, according to the Sistema de Transporte Colectivo’s 2023 accessibility report. Terminal Aérea station has escalators, but Pantitlán does not — you’ll be carrying your luggage up and down stairs. If you’re travelling with more than a carry-on, or if you have any mobility issues, take the Metrobús (which is level-boarding) or a taxi. The Metrobús’s Line 4 stops at street level with ramps at every station.

Three Takeaways

Buy a Tarjeta de Movilidad Integrada card at the airport station for MXN 15 and load MXN 50 — it works on both the Metro and Metrobús, and costs less than a single MTR trip from HKIA to Admiralty.
Use the Metrobús Line 4 from MEX Terminal 1 to Buenavista for a faster, safer, and more comfortable journey into the city centre during daylight hours.
After 9 PM, or if you have more than a carry-on, skip public transit entirely and take the authorised airport taxi from the booth in arrivals — it costs HKD 84-105 and eliminates the risk entirely.
