Connections at MEX: the honest numbers

The indicative minimum international-to-international connection at Mexico City Benito Juárez is 60 minutes on a single booking with bags checked through. On separate tickets, add roughly 90 minutes: you'll collect bags, recheck them, and re-clear security — and no airline is obliged to help if the first leg runs late.

Transfer specifics

Two terminals 3 km apart: T1 (most airlines) and T2 (Aeroméxico/SkyTeam). The free Aerotrén links them in ~5 minutes but runs ~5am–11pm and takes boarding-pass holders with carry-on ONLY — checked bags mean the bus (free for connections, 10–25 minutes, 24h).
Same-terminal international connections want 60 minutes minimum; any T1↔T2 change is 90 minutes bare minimum and 2 hours honest — more late at night. Security and immigration each run up to an hour at peaks.

Leaving MEX during a layover

Australian, NZ, UK, US, Canadian, Japanese and EU passports enter Mexico visa-free as tourists (up to 180 days) — the real tax is time, not paperwork: immigration queues can run to an hour at peaks. The city centre is only ~10 km away but Mexico City traffic is world-class bad — budget 30–60 minutes each way by authorised taxi (buy the ticket at the official taxi counters inside the terminal; don't hail outside). The airport itself sits at 2,230 m altitude — go easy if you're sprinting for a gate. A World Cup-driven renovation is still finishing: expect hoardings and rerouted walkways. The city is about 30 minutes away one-way; as a rule of thumb you want 6+ hours before exiting is worth the queues, and you should be back through security 90 minutes before boarding.

Worth your hours in Mexico City

7h+: authorised taxi to the Centro Histórico — Zócalo, the cathedral and Palacio de Bellas Artes make a tight, walkable loop
8h+: add tacos properly — the Centro's fondas and street stands beat anything at the airport by miles
Traffic honesty: this is a 7-hours-minimum exit. Under that, the city will eat your whole margin in traffic

Staying airside instead

izZzleep sleep capsules — landside in BOTH terminals, rentable by the hour (~2h minimum) with showers included
Six-plus lounges between the terminals, most Priority Pass access weighted toward T1
24-hour eateries in both terminals; free WiFi (CDMX_AICM in T1, AICM_T2 in T2 — registration required)

Sleeping, showers and lounges at MEX

Sleep: The izZzleep capsules (landside, both terminals, ~US$40 overnight, shared showers, safe and luggage storage included — pack earplugs) are the realistic in-airport sleep. For a proper room: the Hilton connects to T1, the NH Collection to T2, and the Camino Real is a short covered walk. Airport hotels & sleep pods

Showers: In lounges and at the izZzleep capsules — there are no standalone public showers.

Lounges: At least six operating across both terminals through the renovation, Priority Pass options concentrated in T1 (five locations vs one in T2). If you hold the card and can influence your terminal, that settles it. Priority Pass membership (frequent flyers)

Overnight reality: Tolerated with a same-day boarding pass, but the free seating is armrest-hostile and announcements run all night — travellers end up on tiled floor. Keep valuables ON you (landside pickpocketing is reported, and never pack valuables in checked bags here). The capsules are worth every peso. Note: no free drinking water airside — fill up landside or budget for bottles.

MEX layover FAQ

Can I leave Mexico City airport during a layover?

Yes — Australian, NZ, UK, US, Canadian, Japanese and EU passports enter visa-free (up to 180 days). But be honest about the maths: immigration can take an hour, the city is 30–60 minutes each way in traffic, and you should be back 2–3 hours before an international departure. Under ~7 hours, stay put.

Is 90 minutes enough to connect at Mexico City?

Same terminal, single booking: 60–90 minutes is workable. Changing between T1 and T2 is the trap — 90 minutes is the bare minimum and 2 hours the honest number, because the Aerotrén (5am–11pm) only takes boarding-pass holders with carry-on, and the fallback bus takes 10–25 traffic-dependent minutes.

How do I get from MEX to the city centre safely?

Use the authorised airport taxis: buy a fixed-price ticket at the official counters inside the terminal and ignore anyone soliciting outside. The Centro Histórico is ~10 km but 30–60 minutes in traffic. Ride-hail apps also work from the terminal but pickup points can be chaotic.

Can I sleep at Mexico City airport overnight?

You can, but the free seating is among the least sleep-friendly of any major hub — armrests everywhere and all-night announcements. The izZzleep capsules (landside, both terminals, hourly rates, showers included) are the answer, or the Hilton (T1)/NH Collection (T2) if you want a real bed.
