Aeromexico allows 1 carry-on and 1 personal item free on all fares. Checked bag allowances depend on your fare and route economy travelers flying to the U.S. get no free checked bag, while Clase Premier passengers receive two. Fees for a first checked bag on U.S. routes start at $30 if purchased online in advance.

Showing up at the airport without knowing your airline’s baggage rules is an expensive lesson most travelers only learn once. Aeromexico’s policy is more nuanced than many U.S. carriers allowances shift depending on your fare class, destination region, and whether you buy baggage before arriving at the check-in desk. Getting familiar with these rules upfront can realistically save you $30–$100 per trip.

What Are Aeromexico’s Carry-On Baggage Rules?

Every Aeromexico passenger regardless of fare type receives one carry-on bag and one personal item at no extra charge. The carry-on must not exceed 55 x 40 x 25 cm (21.5 x 15.7 x 10 inches) and must fit in the overhead compartment. The personal item (a backpack, purse, briefcase, or laptop bag) goes under the seat in front of you.

Can I take a backpack and a carry-on on Aeromexico?

Yes. Aeromexico permits one personal item (such as a backpack) plus one standard carry-on on every fare. The combined weight for both pieces must not exceed 10 kg (22 lbs) in Economy or 18 kg (40 lbs) in Clase Premier. Aeromexico gate agents frequently enforce weight limits, particularly on busy flights so don’t rely on a soft check.

Carry-On Weight Limits by Cabin

Additional items allowed in the cabin free of charge:

• Coat, jacket, or blanket
• Umbrella or walking stick
• Camera (not in a bulky camera bag)
• Duty-free shopping bag
• Diaper bag (when traveling with an infant)
• Mobility aids (crutches, walkers, braces)

Does Aeromexico Give You a Free Checked Bag?

Not always. Whether Aeromexico includes a free checked bag depends entirely on your fare type and route. On U.S.–Mexico routes, no economy fare (Basic, Classic, or Flexible) includes a complimentary checked bag. Only Clase Premier passengers and certain loyalty members receive free checked bags on this corridor.

Here’s the full picture by route:

Checked Bag Allowance by Fare and Region

Key insight competitors miss: Asia routes are the most generous even Basic fare passengers get two free checked bags. Europe routes include one free bag for Classic and above. U.S.-bound travelers in economy are the most disadvantaged under this policy.

Who qualifies for a free checked bag regardless of fare?

• Aeromexico Rewards Titanium, Platinum, and Gold elite members
• SkyTeam Elite and Elite Plus frequent flyers
• Platinum American Express Aeromexico cardholders
• Santander Aeroméxico Infinite cardholders

What Is Aeromexico’s Checked Baggage Size and Weight Limit?

Aeromexico’s checked baggage size limit is 158 cm (62 inches) linear, meaning the combined total of length + width + height cannot exceed this figure. Each checked bag is treated as an individual piece under the piece concept system (used for flights to/from Mexico, U.S., Canada, Europe, Asia, Brazil).

Aeromexico Checked Baggage Weight Limits

Bags exceeding 158 cm but under 203 cm (80 inches) are classed as oversized and charged accordingly. Bags above 45 kg or 294 cm are not accepted at all.

How to measure linear dimensions: Add the bag’s height, width, and depth together. A typical carry-sized checked bag measuring 70 cm x 48 cm x 28 cm = 146 cm total just under the 158 cm limit.

How Much Does It Cost to Check a Bag with Aeromexico?

Aeromexico checked baggage fees vary by route and season. Prices are lower when purchased online in advance versus at the airport counter. Below are fees for Classic, AM Plus, and Premier fares on international routes (USD).

Aeromexico International Checked Baggage Fees (USD)

Note: Fees reflect low/high season rates. LS = Low Season, HS = High Season. Basic fare passengers may pay higher rates. Always confirm current pricing on aeromexico.com before travel.

Overweight and oversized surcharges (on top of bag fees):

• Overweight 23.1–31.9 kg (international): $100 per bag
• Overweight 32–45 kg: $200 per bag
• Oversized (U.S./Canada): $150 per bag
• Oversized (Europe/Asia): $250 per bag

Real cost scenario: A family of three flying economy from New York to Mexico City, each checking one 23 kg bag, will pay $30 × 3 = $90 total if purchased online. Waiting until the airport? No price advantage on U.S. routes fees are the same at check-in. On Canada routes, however, buying online saves roughly $10 per bag.

What Are Aeromexico’s Rules for International Flights?

On Aeromexico international flights, baggage rules follow the “piece concept” meaning allowances are based on the number of individual bags rather than total weight. The exception is certain Central and South American routes (excluding Brazil), where a “weight concept” applies: Economy passengers get a combined 30 kg total, and Clase Premier gets 40 kg combined.

Codeshare and SkyTeam flights: A commonly missed detail if you booked through Delta or another SkyTeam partner, the baggage rules of the marketing carrier (the airline listed first on your ticket) typically apply, not Aeromexico’s. Always verify which airline’s policy governs your specific itinerary.

What Items Are Restricted or Prohibited?

In checked baggage (not permitted):

• Explosives, fireworks, flares, gunpowder
• Flammable liquids (gasoline, lighter fluid, paint thinners)
• Compressed gas cylinders, propane, butane

Liquids rule (3-1-1): All liquids, gels, aerosols, and creams must be in containers of 100 ml (3.4 oz) or less, placed in a single clear resealable bag of approximately 1 liter. One bag per passenger. Exceptions apply for medication, baby formula, and breast milk declare these at security.

Tips to Avoid Unnecessary Baggage Fees

• Buy baggage allowance at booking. Adding bags through “Manage Your Trip” on aeromexico.com is almost always cheaper than paying at the airport.
• Weigh your bags at home. A digital luggage scale costs under $15 and can save you a $100 overweight surcharge at the counter.
• Know the linear measurement. Bags close to 158 cm can get flagged. Measure before you pack.
• Join Club Premier. Even entry-level Gold status unlocks a free extra bag on most routes.
• Label your bags clearly. Use both an external luggage tag and an internal card with your name, phone number, and destination address.
• Consider baggage insurance for high-value items Aeromexico’s liability for lost or damaged checked baggage is limited under international conventions.
