Aeromexico Checked Baggage

Aeromexico caps a checked bag at 25 kg (55 lb) and 158 cm (62 in) total. That total adds length, width and height together. Premier and Premier One get a bigger box at 32 kg (70 lb), against the same 158 cm.

Aeromexico checked baggage rules do not change between a domestic hop inside Mexico and a flight to the United States. The fare you buy matters more than the route. That is the part most travelers get wrong before they book.

The catch sits earlier in the fare list. Main Light, Main Basic, Main Classic, Main Flex and AM Plus Basic carry no free checked bag. The site lists them only as an option to buy a 25 kg piece.

AM Plus Classic and AM Plus Flex include one bag at the standard limit. Premier Basic includes one 32 kg bag. Premier Classic and Premier Flex both include two.

Checked baggage allowance by fare

Aeromexico Rewards Titanium, Platinum and Gold cardholders get one extra piece. It matches their fare class weight and size. That is worth checking before paying at the counter.

Every figure above comes off the carrier’s own baggage allowance page. Recheck it before you fly, since fare names shift.

What a first checked bag costs on Aeromexico

Buying a bag you were not given free is priced by season and by piece count. On the domestic Mexico routes the carrier publishes, a first extra piece on a Light fare runs about 1,645 MXN in low season. In high season that same piece rises to about 2,025 MXN.

A second piece runs roughly 2,025 to 2,405 MXN by season. A third through seventh piece climbs to about 2,405 to 2,785 MXN.

International routes price in the currency of the region flown to. Buying online ahead of the airport is consistently cheaper than paying at the counter.

What cannot go in the hold on Aeromexico

Power banks are the item most travelers get wrong on Aeromexico checked baggage. A power bank like the small ones travelers carry is allowed only in the cabin, never checked, and up to two per person.

Each power bank must stay under 100 Wh. It may never sit in a checked bag or the overhead bin.

Smart bags and hoverboards with lithium-ion batteries are barred from the hold on this forbidden and restricted baggage list. So are lighters, matches, tools that run on fuel, and dry ice past the declared medical amount.

Firearms and ammunition ride as checked baggage only when declared at the counter. Alcohol, perfumes and machinery lubricants count as restricted liquids and must stay under the stated volume.

Connecting bags and interline itineraries

On a single ticket through Mexico City or another Aeromexico hub, the airline checks bags to the final stop. It applies its own allowance for the segments it operates.

When a codeshare or interline partner flies part of the trip, the rule that governs is usually the strictest one on the itinerary. That mirrors the most significant carrier standard the Department of Transportation sets for US connections. Ask the counter agent which allowance applies before check-in.

Overweight, oversize and gate reality

A bag over the weight or linear limit for its fare is charged as an oversize or overweight piece, not turned away outright. The fee scales with how far over the bag runs.

Community reports describe agents at Mexico City and major US gateways weighing every bag rather than eyeballing it. A scale at home avoids a surprise at check-in.

Aeromexico does not publish a right to pool weight across two checked bags on one ticket. Plan each bag to its own limit rather than counting on the counter to average them.

Lightweight bags that fit the Aeromexico box

A 25 kg allowance rewards a case that starts light empty. Every kilogram of shell weight is a kilogram you cannot pack.

The 158 cm linear limit is generous enough that most 24 to 29 inch cases clear it with room to spare. Weight decides more than size on this carrier.

• The Travelpro Maxlite 5 25 inch expandable spinner is one of the lightest cases in its class empty. That leaves more of the 25 kg for what you pack.
• The Travelpro Maxlite 5 29 inch suits the 32 kg Premier allowance for a longer trip. Its empty weight stays low too.
• The Samsonite Omni PC 24 inch and the larger Samsonite Omni PC 28 inch are hardside picks reviewers rate well for durability. Both weigh more empty than the Maxlite line.
• The Amazon Basics 30 inch hardside checked luggage is the cheapest option here. At 30 inches, measure it before assuming it clears any airline’s linear limit.
• An Etekcity digital luggage scale costs less than a single overweight fee. It settles the question before you leave the house.

Anyone flying Aeromexico against another Latin American carrier can compare numbers directly. Volaris checked baggage and Copa Airlines checked baggage both publish their own weight and piece rules. Neither matches Aeromexico’s 25 kg standard exactly.

For the cabin side of the same fare, see Aeromexico carry-on size. For how the fee table breaks down by route, see Aeromexico baggage fees.

The general rules for checked baggage weight limits and for overweight and oversize baggage fees explain how airlines set these bands. Run the numbers through the baggage cost tool to see what a second or third piece costs on your route.

The bottom line

Aeromexico checked baggage comes down to one number, 25 kg, and one question: does your fare include a bag at all. Basic and Light fares do not. AM Plus Classic and Premier fares do.

Weigh the bag before the airport. Keep power banks and lithium-ion smart bags out of the hold. Buy any extra piece online rather than at the counter, since that is where Aeromexico checked baggage costs the least.
