Mexico City Benito Juárez MEX
Crowded, cramped, and open all night anyway.
Yes, but manage your expectations. Both terminals stay open through the night and people sleep here routinely; there are no rest areas, seating is limited, and the two terminals are awkward to move between.
Good to know
Terminals 1 and 2 are separate buildings and the connecting train does not run continuously overnight.
Buy taxi transport only from the official counters inside the terminal, or use a ride-hailing app from the designated pickup point.
If your budget stretches at all, a terminal hotel room beats a night in the MEX concourse by a wide margin.
Seating pressure is worst during weather or air traffic disruptions, when the concourses fill well beyond their seat count.
What to do here overnight
The moves that actually pay off between midnight and dawn.
Sleepability score
Airside vs landside
Terminals 1 and 2 are separate buildings on opposite sides of the airfield, connected by an elevated automated train for ticketed passengers and by a road shuttle otherwise — neither runs continuously through the night. Airside areas in both terminals remain open, but they are cramped and seating fills quickly during disruptions. International-to-international connections generally stay airside; anything touching a domestic flight puts you through immigration and back out landside. The single most consequential overnight decision at MEX is being in the right terminal before the inter-terminal links go quiet.
Where to sleep
There is no good free option, only less bad ones. Terminal 2's airside waiting areas tend to be marginally calmer than Terminal 1's, and the upper levels of both buildings are quieter than the arrivals floors. Nearly all seating has fixed armrests, so a genuine lie-down means the floor, and the floor is busy with foot traffic all night. The realistic answer at MEX is a paid option: a lounge with recliners, a capsule-style rest facility if one is operating, or one of the hotels attached to or adjacent to the terminals, which is the move most seasoned travelers make here.
Lounges, scored for sleeping
Lounges are where MEX becomes tolerable. The better ones sit in Terminal 2, including a card lounge and the home carrier's flagship, with pay-per-use options on the Terminal 1 side. None run right through the night and several get crowded, but even a couple of hours in a recliner with a shower is worth the entry price given what the concourses are like.
Comfortable, well-fed and a big step up from the concourse, though it closes for part of the night and gets crowded.
The home carrier's lounge with showers; hours follow Aeroméxico's departure banks.
Pay-per-use and Priority Pass access in Terminal 1 — the main option on that side of the airport.
Basic walk-up lounge; buys you a seat and quiet rather than a proper rest.
24-hour services
MEX holds onto more overnight food than most airports its age, and what stays open tends to be genuinely good and reasonably priced — taquerías and coffee counters rather than sad sandwiches. The selection narrows in the deep hours but rarely disappears entirely. Landside options near the metro side close earlier.
By terminal
The older, busier and more crowded terminal; open all night but short on seating and quiet space.
Newer and marginally calmer, and home to the better lounges; still cramped by international standards.
Night transport
The Mexico City metro has a station beside Terminal 1 but does not run through the night, and it is not designed for luggage in any case. Overnight transport means authorized airport taxis bought from the official counters inside the terminal, or ride-hailing from the designated pickup points. Traffic in Mexico City is punishing at almost every hour except the middle of the night, when a transfer that takes an hour by day takes twenty minutes.
Safety & solo travelers
The terminals are staffed and policed overnight, but MEX has a long-standing reputation for opportunistic theft and for unauthorized taxi touts working the arrivals halls. Buy ground transport only from the official counters or an app, never from someone who approaches you. Sleep in populated, well-lit areas within sight of staff, keep your bag straps physically around you, and keep phones and documents out of outside pockets.
Family & accessibility
Facilities for families are thin relative to the passenger volume — there are nursing rooms and family restrooms, but no play area worth planning around and very little spare seating. With children, book a room at one of the terminal-adjacent hotels rather than attempting a night in the concourse.
Common questions
Can you sleep in Mexico City Airport overnight?
Yes, both terminals stay open through the night and people do sleep there. It is not comfortable: seating is limited and has armrests, the concourses are bright and busy at all hours, and there is no dedicated rest area. If you can afford a terminal hotel room, take it.
Is Mexico City Airport open 24 hours?
Yes. Benito Juárez operates continuously and both terminals remain accessible overnight, with some food outlets running through the small hours. The train connecting the two terminals does not run all night, which matters more than the terminal hours themselves.
How do I get between Terminal 1 and Terminal 2 at MEX?
An elevated automated train links the two buildings for passengers with a boarding pass, and a road shuttle covers the rest. Neither operates continuously overnight, so move to your departure terminal before the evening service ends rather than after.
Is Mexico City Airport safe at night?
The terminals are policed and staffed, and violent crime inside is not the concern. Opportunistic theft and unauthorized taxi touts are. Buy ground transport only at the official counters or through an app, keep your bags secured to you while you sleep, and stay in busy, well-lit parts of the concourse.
Is there a hotel inside Mexico City Airport?
Yes — there are hotels directly connected to or immediately adjacent to both terminals, and several accept late arrivals and short day-use stays. Given how uncomfortable the concourses are overnight, this is the option most experienced travelers default to here.
Where can I shower at Mexico City Airport?
Showers are inside the paid and airline lounges rather than in public facilities. If the lounge hours do not line up with your layover, a day-use room at a terminal hotel is the reliable alternative.
