Quick Answer
For most travelers, the best way to get from Mexico City Airport (AICM) to UNAM Ciudad Universitaria is by Uber/Cabify or official airport taxi, taking 30 to 60 minutes and costing between 350 to 650 MXN (≈$20-38 USD). For the cheapest option, take the Metro + Bus combination for under 30 MXN (≈$1.75 USD), but it requires multiple transfers and is not luggage-friendly.
Metro & Public Bus: The Budget Champion
This is the absolute cheapest method, costing less than a coffee. However, it's a journey for the adventurous, light-packing traveler as it involves multiple transfers, stairs, and crowded vehicles. It is not recommended for those with large suitcases, mobility issues, or arriving late at night.
Key Route: Metro Línea 5 (Yellow) → Metro Línea 3 (Olive) → Public Bus (RTP or other).
Step-by-Step Breakdown:
| Step | Action | Estimated Time | Cost | Notes |
|---|---|---|---|---|
| 1 | Walk to Metro Terminal Aérea (T1) or Hangares (T2). | 10-15 min walk | Free | Follow signs inside the terminal. From T2, it's a longer, uncovered walk. |
| 2 | Take Metro Línea 5 (Yellow) towards Politecnico. Get off at La Raza. | 15 min | 5 MXN | Buy a single-use card at the station. This line can be very crowded. |
| 3 | Transfer to Metro Línea 3 (Olive) towards Universidad. Get off at the final stop, Universidad. | 20 min | No extra fare | Free transfer within the system. This station is directly outside UNAM's south perimeter. |
| 4 | Take a Public Bus (RTP, etc.) into Ciudad Universitaria. | 10-20 min | 2-6 MXN | Buses like RTP Line 2 go deep into campus. Have small change ready. |
Total: 90-120 minutes | ~20-30 MXN (≈$1-1.75 USD)
Who Should Use This Method?
- Backpackers or travelers with one small bag.
- Those on an extremely tight budget.
- Travelers arriving during daylight hours who are comfortable with urban navigation.
Metrobús & Direct Airport Buses: A Balanced Option
This option offers a good middle ground between cost and comfort, providing a more direct route than the standard metro without the price of a taxi.
Option A: Metrobús Línea 4
The Metrobús is a bus rapid transit system with dedicated lanes. Línea 4 (San Lázaro – Buenavista) stops at Terminal Aérea (near T1).
- From T1: Exit Terminal 1, cross the pedestrian bridge to the “Terminal Aérea” Metrobús station.
- From T2: You need to take the Terminal 2 internal shuttle bus to T1 first (free, ~10 min).
- Journey: Take Línea 4 south to station “Dr. Gálvez” (formerly “Centro Médico”).
- Final Leg: From Dr. Gálvez, you must transfer to a bus or taxi to reach UNAM (approx. 15-20 min). Buses heading south on Insurgentes Avenue are available.
Pros: Faster than regular traffic during rush hour, frequent service.
Cons: Not a door-to-door service, requires a final transfer. Requires a pre-paid “Tarjeta MB” card (available at stations, ~16 MXN cost + recharge).
Cost: 30 MXN per ride (using the MB card).
Option B: Direct Bus Services (Aeroméxico & Metrobsú)
These are comfortable coach-style buses with luggage compartments, offering direct service between the airport and major city hubs closer to UNAM.
| Service | Route | Closest Stop to UNAM | Cost (One-Way) | Notes |
|---|---|---|---|---|
| Aeroméxico Bus | Airport (T1 & T2) → Zona Rosa/South | World Trade Center (WTC) or Auditorio Nacional | ~120 MXN | Comfortable, reliable, free WiFi. From WTC, a taxi to UNAM is ~15 min. |
| Metrobús Directo Aeropuerto | Airport (T1) → Buenavista | Buenavista Station | 30 MXN (MB card) | From Buenavista, you are north of the city center; a long taxi/metro to UNAM is needed. |
Best For: Travelers with more luggage than for the metro but wanting to save compared to a full taxi fare to UNAM.

Traveler Insights & Pro Tips
Essential Advice for a Smooth Transfer
- Beware of Unofficial Taxis: Politely but firmly decline offers from individuals inside the terminal claiming to be taxi drivers. Always use the official booth or a pre-booked service. (Official AICM Transport Advice).
- Traffic is Your Biggest Variable: The 20km journey can double in time during rush hours (7-10 AM, 6-9 PM). Factor this in if you have a tight schedule.
- Have Mexican Pesos (Cash): While taxis and apps take cards, having cash (especially smaller bills for buses, tips, or emergencies) is crucial. ATMs are available in arrivals.
- UNAM is Massive: Ciudad Universitaria is a huge campus. Know your specific destination (Faculty, building, gate) to give the driver precise instructions and avoid driving in circles.
- Altitude & Hydration: Mexico City is at 2,250m (7,380ft). You may feel fatigued more quickly, especially if carrying luggage. Take it easy and drink water.
- Data is King: A local SIM card or eSIM with data (available at airport kiosks) is invaluable for using maps, rideshare apps, and translating.
Special Scenarios
- Traveling with a Group (4+): Consider pre-booking a private van transfer service. The total cost can be similar to multiple taxis, and it's more coordinated.
- Late-Night Arrival (Past 11 PM): Your best and safest bets are the official airport taxi or a pre-booked private transfer. Public options are very limited or inadvisable.
- Early Morning Departure from UNAM: When returning to the airport, schedule your Uber/Cabify the night before. Traffic is lighter very early, but driver availability can be sparse.
