If you are searching “why can’t I check in on Aeroméxico?”, the problem is not necessarily your ticket or reservation. Aeroméxico offers online, mobile and airport check-in, but the available process depends on factors such as your route, fare, operating airline and booking information.
Aeroméxico currently says web check-in is available 48 hours before departure for domestic flights and 24 hours before departure for international flights. There is also a special rule for a Basic fare on a domestic route: digital check-in opens 24 hours before departure.
The airline allows passengers to locate a reservation using either a six-digit reservation reference or a 13-digit ticket number, together with the passenger's last name.
If your Aeromexico online check-in is not working, the best approach is to identify the reason first instead of repeatedly refreshing the page. This guide covers the most common causes and practical solutions.
Aeroméxico check-in can be unavailable for several reasons. Sometimes the problem is simply that you are outside the applicable check-in period. In other cases, the reservation may require additional processing, your flight may be operated by a partner airline, or the website or app may be experiencing a technical problem.
Before assuming there is something wrong with your ticket, check these possibilities:
This is one of the simplest explanations for an unavailable check-in option.
Aeroméxico says online check-in opens:
So, for example, a passenger flying internationally should not expect the standard web check-in option to become available two days before departure.
What to do: Check your departure date and time, identify whether the flight is domestic or international, and try again when your applicable check-in window opens.
Aeroméxico's check-in page accepts either a six-digit reservation reference or a 13-digit ticket number. You also need to enter the passenger's last name.
This is important if you purchased your ticket through a travel agency or another booking website. You may have several reference numbers, but they may not all work as the Aeroméxico reservation reference.
Try this:
A spelling or formatting difference can prevent the system from finding your reservation.
Check the name against your booking confirmation rather than entering what you normally use on other travel websites.
If you have multiple surnames, use the information in the reservation and follow the format requested by Aeroméxico's check-in page.
Aeroméxico has a specific check-in rule for Basic fares on domestic routes.
The airline says that while many domestic flights allow digital check-in 48 hours before departure, a Basic fare on a national route can be checked in 24 hours before departure.
Therefore, if you have a Basic domestic ticket and try to check in 30 or 40 hours before departure, the system may not yet be ready to process your check-in.
A ticket can be sold through Aeroméxico while a particular flight is actually operated by another airline.
Aeroméxico provides separate information for flights operated by partner airlines, meaning the check-in procedure can differ depending on the operating carrier.
Look at your itinerary for the operating-airline information.
If the flight is operated by Delta, Air France, KLM or another partner, check Aeroméxico's instructions for that particular itinerary before assuming the Aeroméxico website is broken.
A recent change to your flight can temporarily interfere with check-in.
This can happen after:
If your booking has changed recently, open the latest itinerary rather than relying on an older confirmation email.
What to do: Confirm the current flight number, departure time and operating carrier before attempting check-in again.
International flights can involve additional travel-document and entry requirements.
Aeroméxico provides a country-specific travel-requirements tool to help passengers determine what documentation may be required for their destination.
If the check-in process asks for additional information, complete the requested fields accurately.
Do not enter information from memory if your passport or travel document is available. Use the document as the source of truth.
Sometimes Aeromexico online check-in not working really is a website issue.
You may see symptoms such as:
If the reservation works on another device but not yours, the problem may be browser- or device-related.
Aeroméxico offers mobile check-in and a mobile boarding pass, and the airline's current app also supports check-in and real-time flight information.
If the app is not working:
Conversely, if the website is failing, try the app.
Not every passenger or itinerary can necessarily be completed entirely online.
Aeroméxico provides airport kiosks that can be used for check-in, boarding-pass printing, baggage-tagging and other airport procedures.
If online check-in remains unavailable after you've verified your booking, airport processing may be the quickest solution.
If you are looking for Aeromexico check-in error how to fix, follow these steps in order.
First determine whether your flight is domestic or international.
For standard online check-in, Aeroméxico currently states:
For Basic fares on domestic routes, the airline states that digital check-in starts 24 hours before departure.
Aeroméxico allows you to retrieve your reservation using:
You must also enter the passenger's last name.
Double-check every character before trying again.
If your itinerary includes another carrier, determine which airline operates the actual flight.
Aeroméxico provides separate check-in guidance for partner-operated flights.
Look for a recent schedule change, cancellation or rebooking.
If the flight information has changed, use the current itinerary instead of an old confirmation.
If the reservation details are correct, test the website using another browser.
For example, if you normally use Chrome, try Edge, Firefox or another supported browser.
You can also open a private/incognito window to avoid problems caused by stored website data.
The airline offers mobile check-in and boarding-pass functionality.
If the website is failing, the app can provide another way to access your trip.
Try switching between:
A poor connection can interrupt the check-in process before the boarding pass is generated.
If possible, try another phone, tablet or computer.
This can quickly show whether the problem is specific to your original device.
If you need to know what to do if Aeromexico online check-in fails, don't panic.
Start by checking whether your flight is inside the appropriate check-in period. Then verify your booking reference or ticket number and last name.
If the information is correct, check whether your flight is operated by Aeroméxico or a partner airline. After that, try the app, another browser and another device.
If none of these works, use Aeroméxico's airport check-in options.
The airline offers check-in kiosks at airports where the service is available. These kiosks can be used to check in and print a boarding pass, and they can also support baggage-tagging procedures.
A successful Aeromexico flight check-in should give you access to your boarding pass.
Aeroméxico offers mobile check-in with a mobile boarding pass, and its airport kiosks can also print a boarding pass.
If you have completed check-in but cannot see the boarding pass, try accessing the reservation again through the website or app.
Try the following:
Do not assume that a missing digital boarding pass means the booking has been cancelled.
Yes. Aeroméxico provides several airport check-in options.
Its current check-in information includes web check-in, mobile check-in and airport kiosks.
At an eligible kiosk, passengers can:
If the online process fails, airport check-in is therefore an important alternative.
Online check-in does not mean your checked baggage has already been handed over to Aeroméxico.
After obtaining your Aeromexico boarding pass, you still need to complete the applicable baggage process at the airport.
Aeroméxico says its kiosks can support baggage-tagging and baggage-drop procedures at participating airports.
Give yourself enough time for check-in, baggage acceptance, security and any immigration procedures.
Do not automatically assume that an Aeroméxico ticket means every check-in step will take place through Aeroméxico.
Aeroméxico has dedicated information for flights operated by partner airlines.
Look for the phrase “operated by” on your itinerary.
If another airline operates your flight, follow the appropriate check-in instructions for that carrier.
A Basic fare does not necessarily prevent online check-in.
However, Aeroméxico specifically says a Basic fare on a domestic route has a 24-hour digital check-in window, compared with 48 hours for many other domestic fares.
If your Basic domestic flight is not yet within 24 hours of departure, the check-in option may not be available.
For international flights, Aeroméxico currently states that web check-in becomes available 24 hours before departure.
If you are already within that window but cannot complete check-in, verify:
Aeroméxico also provides a country-specific travel-requirements tool, which can help identify documentation requirements for your journey.
Use this checklist when your Aeromexico check in is not working:
If your flight is getting close and you have already tried the basic troubleshooting steps, stop spending valuable time refreshing the website.
Aeroméxico provides airport kiosks specifically for check-in and boarding-pass printing, along with baggage-tagging functions at participating airports.
Arriving at the airport with your reservation information and required travel documents is more useful than continuing to fight with a failing website.
If you have checked baggage, an international flight or any special travel requirement, allow additional time for airport processing.
You may be trying too early, using incorrect reservation information, traveling on a partner-operated flight, dealing with an itinerary change or experiencing a technical issue. Your fare can also affect when digital check-in opens.
Aeroméxico check-in may be unavailable because the applicable check-in period has not opened, your reservation details do not match, your itinerary has changed or the flight requires a different check-in procedure.
Aeroméxico currently says web check-in opens 48 hours before domestic flights and 24 hours before international flights. Basic fares on domestic routes have a 24-hour digital check-in window.
Verify your reservation reference or ticket number and last name first. Then check the timing, operating airline and itinerary. If those are correct, try another browser, device, internet connection or the Aeroméxico app.
Try the website again using another browser or device, then try the Aeroméxico app. If the problem continues, use an airport kiosk or ask Aeroméxico staff to complete the check-in process.
Yes. Aeroméxico provides airport check-in kiosks at participating airports, where passengers can check in and print a boarding pass.
You can obtain your boarding pass through Aeroméxico's web or mobile check-in process. The airline also provides boarding-pass printing through airport kiosks at participating locations.
Aeroméxico says you can locate your reservation using either a six-digit reservation reference or 13-digit ticket number, along with your last name.
Yes. For domestic routes, Aeroméxico states that Basic fares have digital check-in available 24 hours before departure rather than the 48-hour window applicable to many other domestic fares.
Yes. If another airline operates your flight, the check-in process can be different. Aeroméxico provides separate guidance for flights operated by partner airlines.
First confirm that check-in was successfully completed. Then try reopening your reservation through the website or app. If the boarding pass still cannot be retrieved, use an airport kiosk or contact Aeroméxico staff.
Yes. Aeroméxico's current app supports check-in, trip management and real-time flight information, and the airline offers mobile boarding-pass functionality.
Not necessarily. Passengers with checked baggage still need to complete the baggage process. Depending on the itinerary and airport, you may also need document or other airport processing.
If you are searching “why can’t I check in on Aeroméxico?”, start by checking the timing and your reservation details. Aeroméxico currently offers online check-in from 48 hours before domestic flights and 24 hours before international flights, with a 24-hour rule for Basic fares on domestic routes.
If Aeromexico online check-in is not working, verify your six-digit reservation reference or 13-digit ticket number and passenger surname. Then check whether your itinerary has changed or whether another airline operates the flight.
If the information is correct, try the Aeroméxico app, another browser, another device or a different internet connection. Aeroméxico also provides airport kiosks that can be used for check-in and boarding-pass printing at participating airports.
Most importantly, don't wait until the last minute. If the online system continues to fail, take your booking information and required travel documents to the airport and use the available Aeroméxico check-in facilities. A failed online check-in is inconvenient, but it does not by itself mean you cannot travel.
