Oxygen: Aeroméxico can actually supply it, if you beat the clock
Two different rules depending on whose equipment flies.
Plenty of airlines put the whole burden on the passenger: bring your own concentrator or don't fly. Aeroméxico still offers airline-supplied oxygen, and the trade is time. The request must be made no less than 72 hours before a domestic flight and no less than 96 hours before an international one. Those are floors, not targets, and there's no negotiating them at the airport, the equipment either got loaded for your flight or it didn't.
Domestic, book it at least 72 hours out. International, at least 96. If your trip mixes both, work to the international number and stop cutting it fine.
Bringing your own FAA-approved portable oxygen concentrator is handled differently: it sits on the 48-hour advance-notice list rather than the oxygen booking window. Still not a counter conversation, but a shorter runway.
Medical-oxygen conditions, documents and any applicable charges vary by case and route; we confirm the full requirements for your flight before anything is booked, and you can arrange it directly with Aeroméxico at no cost.
The 48-hour list: what needs advanced check-in
Aeroméxico's own grouping, and it's broader than people assume.
Aeroméxico asks to be told 48 hours in advance about services that require advanced check-in. On its own special-services pages, that list covers three things: traveling with your own FAA-approved portable oxygen concentrator, checking in a wheelchair with a dry battery, and groups of 10 or more passengers with disabilities traveling together. The pattern is anything that needs ground staff to prepare something, rather than just meet you with a chair.
One honest note on what the airline does not say: we found no published split of that notice period into different figures for domestic versus international, so if someone quotes you one, treat it with suspicion. The published framing is 48 hours, and where your case is unusual, the safe move is more notice, not a creative reading of the minimum.
Serious illness: 72 business hours, and business is the word to watch
The quiet detail in Aeroméxico's wording that changes your real deadline.
For passengers traveling with a serious illness or disability that needs case-by-case handling, Aeroméxico recommends contacting its call center 72 business hours in advance. Read that phrase twice, because it is not the same as three days. Business hours don't run through weekends, so a Monday-morning flight arranged the previous Thursday can already be inside the window. This is the kind of arithmetic nobody does until it's too late, and it's precisely why we tell families dealing with a medical situation to make this the first call of the planning, not the last.
If your situation involves specific equipment, a recent hospitalization, or anything a gate agent might question, get it onto the reservation through the call center early and keep whatever confirmation you're given. A note in the booking beats a verbal assurance every time.
Requirements for medical cases vary by condition and route and can change; confirm your specific case with Aeroméxico or call us and we'll work through it with you.
Wheelchairs and mobility assistance
Available throughout, with one battery-specific deadline.
Wheelchair and mobility assistance is available on Aeroméxico, and for most travelers the practical advice is simple: put the request on the reservation when you book so staff are expecting you, whether you're departing a US city or connecting in Mexico City. The one firm timing rule the airline attaches is for wheelchairs with dry batteries, which fall under the 48-hour advanced check-in request above, because a battery-powered chair has to be prepared and documented for the hold rather than simply gate-checked.
Tell us what you travel with, manual chair, powered chair, scooter, and we'll confirm with the airline how yours has to be presented before you're standing at the counter finding out.
Emotional support animals: the rule US carriers dropped, Aeroméxico kept
The genuine differentiator on this page, and the reason some travelers pick this airline.
American, Delta and United all stopped accepting emotional support animals. Aeroméxico did not. Under rules in place since October 2021, an ESA can still fly: dogs and cats only, up to 12 kg (26 lb), fitting a space of about 22 x 12 inches. For a traveler whose ESA is the difference between flying and not flying, that policy alone can decide the airline, and most people have no idea it exists because they assume every carrier followed the US majors.
Since October 2021 Aeroméxico accepts trained service dogs only, no pigs, monkeys or miniature horses. The airline publishes no weight limit for service dogs, so nobody should quote you one as Aeroméxico's rule. The 12 kg figure belongs to ESAs, not service animals.
The cap counts everything together: a cabin pet, an ESA and a service dog cannot be stacked. One passenger, one animal. Plan the trip around that before anyone falls in love with a two-animal itinerary.
Animal documentation varies by destination country and changes; the full detail lives on our Aeroméxico pets & service animals page, and we confirm your route's exact requirements on the call.
Before you fly, the checklist
Each line maps to a deadline above, work them in order.
- Airline-supplied oxygen requested? 72 hours out for domestic, 96 for international, no exceptions at the airport
- Serious illness or disability? Call-center request 72 business hours ahead, count weekends out of the math
- Own POC or dry-battery wheelchair? On the 48-hour advance-notice list, flag it when you book
- Traveling with an animal? One per passenger total, ESA limits apply, service-dog documents vary by route
Book the assistance before you shop the fare. Every deadline on this page is measured from departure, and fare-watching eats days. If oxygen, a battery-powered chair or a medical case is part of your trip, lock the request windows first and let the fare be the second decision. When you call us, we run the deadlines against your dates before we quote anything.
