Heading to Mexico or flying internationally with Aeromexico? Before you start packing, you need to know the rules.
Airline baggage policies are notorious for changing when you least expect them. Aeromexico is no exception, having recently updated its pricing structure for 2025 and 2026 on select routes. Getting it wrong can result in steep fees at the check-in counter, money better spent on tacos and tequila.
Aeromexico Baggage Policy: At a Glance
If you are in a rush, here is the quick summary of what you are allowed to bring.
| Baggage Type | Allowance | Max Weight | Max Dimensions |
| Personal Item | 1 Included (All fares) | Part of carry-on total | Must fit under seat |
| Carry-On Bag | 1 Included (All fares) | 10 kg (22 lbs) standard* | 55 x 40 x 25 cm (21.5 x 15.7 x 10 in) |
| Checked Bag | 0 to 2 (Depends on fare) | 23kg (50lbs) or 25kg (55lbs) | 158 cm (62 in) linear |
Note: Clase Premier passengers get a higher combined carry-on weight limit of 18kg (39 lbs).
1. Carry-On Baggage Rules
Aeromexico is relatively generous with carry-on allowances compared to some low-cost carriers, but it is strict about weight.
The “Standard” Allowance
For almost every ticket (including Basic Fare), you are allowed:
- 1 Personal Item: This must fit under the seat in front of you. Examples include a handbag, a laptop bag, or a small backpack.
- 1 Carry-On Suitcase: This goes in the overhead bin.
The Weight Limit Trap
This is where travelers get caught. The weight limit is combined.
- Economy (Basic, Classic, AM Plus): Your carry-on suitcase + your personal item must not exceed 10 kg (22 lbs) total.
- Clase Premier: Your carry-on suitcase + your personal item must not exceed 18 kg (39 lbs) total.
Pro Tip: If your laptop is heavy, putting it in your carry-on might push you over the 10kg limit. Aeromexico staff frequently weigh carry-on bags at the gate, especially on full flights.
2. Checked Baggage Allowance
Your checked bag allowance depends entirely on your fare class and your route.
Domestic Flights (Within Mexico)
- Basic Fare: 0 bags included (Fee applies).
- Classic Fare: 1 bag included (max 25 kg / 55 lbs).

3. Excess Baggage Fees (2026 Rates)
If you bring more than your ticket allows, or your bag is heavy, prepare to pay. Aeromexico uses a High Season vs. Low Season pricing model.
Extra Bag Fees
Prices are estimates based on standard USD/MXN exchange rates and subject to tax.
| Route | 1st Extra Bag (Low Season) | 1st Extra Bag (High Season) |
| Within Mexico | ~$30 USD (600 MXN) | ~$45 USD (800 MXN) |
| US & Canada | $30 – $40 USD | $35 – $45 USD |
| Europe | $60 USD | $65 USD |
| South America | $40 – $60 USD | $45 – $70 USD |
Overweight & Oversized Fees
These fees apply on top of any standard baggage fee.
- Overweight (23kg to 32kg): Approx. $100 USD (international) or 700 MXN (domestic).
- Oversize (Max 158cm to 204cm): Approx. $150–$250 USD depending on the route.
Warning: Bags weighing more than 32 kg (70 lbs) or measuring more than 204 cm (80 inches) will generally not be accepted as checked luggage and must be shipped as cargo.
4. Special Baggage: Sports & Instruments
Flying with a surfboard, bike, or guitar? Aeromexico classifies these as “Special Baggage.”
Musical Instruments
- Small Instruments: Can be brought on board as your carry-on item if they fit in the overhead bin or under the seat (max 115 cm linear).
- Large Instruments (Cellos/Guitars): Must be checked.
- Fee: ~$75 USD (Domestic) / ~$150 USD (International).
Sports Equipment
This includes bikes, surfboards, golf clubs, and ski equipment.
- Fee: ~$75 USD (Domestic) / ~$150 USD (International).
- Packing: Items must be in a rigid, protective case. Pedals on bikes must be removed, and handlebars turned sideways.
Exception: Some “Classic” and “Premier” fares may allow you to swap a regular checked bag for a piece of sports equipment for free, but this is route-dependent. Always call ahead to confirm.
5. Exceptions and Freebies
You might be able to skip the fees if you fall into one of these categories:
Club Premier Members
Titanium, Platinum, and Gold members generally get one extra checked bag free of charge on top of their fare allowance.
SkyTeam Elite
Elite and Elite Plus members from partner airlines (like Delta or Air France) receive one extra bag (up to 23kg).
Aeromexico Visa Cardholders
Specific Santander or American Express Aeromexico cardholders may be entitled to free baggage.
Infants
- Lap Infant: 1 piece of checked luggage (max 23 kg) + 1 stroller/bassinet is often included free on international routes.
- Strollers: One stroller can usually be checked at the gate free of charge for any child ticket.
Tips to Avoid Fees on Aeromexico
Weigh Before You Go
Since the carry-on limit is a combined 10kg, it is very easy to exceed. Buy a portable luggage scale.
Pre-Pay Online
While the April 2025 update standardized some pricing, paying for bags via the Aeromexico app or website 24 hours before your flight is still generally cheaper (and safer) than paying at the airport counter.
Join the Club
Even the base level of Club Premier (now Aeromexico Rewards) can offer perks.
Wear Your Heaviest Clothes
If your carry-on is 11kg, put on your coat and heavy boots to get it down to 9.9kg.
Check Partner Rules
If you booked your Aeromexico flight through Delta or another SkyTeam partner, the baggage rules of the marketing carrier (the airline listed first on your ticket) usually apply.
Frequently Asked Questions
Can I pool my baggage allowance with my family?
Generally, no. Baggage allowance is individual. However, if you are checking in together at the same counter, agents are sometimes lenient if one bag is 24kg and another is 20kg, but don’t rely on it.
What is the fee for a dog in the cabin?
For 2025/2026, the fee for a pet in the cabin is approximately $135–$175 USD depending on the destination. The combined weight of the pet and carrier must not exceed 9 kg (20 lbs).
Does the Basic Fare really have NO checked bags?
Correct. If you book the cheapest “Basic” fare to the US or Europe, you have 0 checked bags. You will have to pay roughly $60–$75 USD each way to add one later.
What happens if my carry-on is 1kg overweight?
Strictly speaking, you will be forced to check it and pay the gate-check fee. While some agents are nice, Aeromexico is stricter than US airlines regarding carry-on weight.
Final thought
By sticking to the 10kg limit for the cabin and pre-booking any checked luggage online, you can breeze through Benito Juárez International Airport without opening your wallet.
