Mexicana caps carry-on and personal item weight together at 10 kilograms. That is not 10 kilograms per bag. Two small bags can still tip the scale together, which is the detail Mexicana airlines baggage fees questions usually come down to.
This is not the Mexicana that grounded its fleet in 2010. The current Mexicana de Aviacion is a state owned relaunch. It began flying again in December 2023, operated by Aerolinea del Estado Mexicano.
Its route map is entirely domestic Mexico. Cities like Guadalajara, Merida, Monterrey, Tijuana, Los Cabos and Tulum are typical stops, flown out of hubs including the Felipe Angeles airport. There is no US service, so every figure below applies to a Mexico to Mexico ticket.
Carry-on size and the combined weight rule
A cabin bag must fit within 45 by 25 by 25 centimeters. That is roughly 17.7 by 9.8 by 9.8 inches. A second personal item is also allowed, such as a purse, backpack, laptop bag or camera.
It has to fit under the seat ahead. The catch is the weight rule: the carry-on and the personal item together cannot pass 10 kilograms, about 22 pounds. Run your bag through a size checker before the airport.
A laptop and a full water bottle can push a small backpack past that shared limit fast. Mexicana airlines baggage fees rarely start with the cabin bag itself, since carry-on is free within this limit.
Checked baggage weight and dimensions
Each checked bag can weigh up to 25 kilograms, about 55 pounds. The three dimensions added together cannot pass 158 centimeters, or 62 inches. That works out to roughly 15 by 27.6 by 19.7 inches for a single suitcase.
Go over that weight and Mexicana charges 149 Mexican pesos per additional kilogram. That figure comes from the airline’s own frequently asked questions page. There is no flat overweight fee published, so the cost scales with how far over you are.
What your fare actually includes
Mexicana states plainly that what your ticket includes depends on the fare you buy. That covers any checked bag allowance too. The airline does not publish a fixed table of basic, standard and flexible fare inclusions on its public site.
The safest habit is to check the baggage line on your own booking confirmation. Do not assume last year’s rule still applies. Mexicana airlines baggage fees for a checked bag can shift with the fare and the route.
If your trip involves a partner carrier, compare the full baggage fees for both legs before you fly.
Connecting onward to the United States
Mexicana does not fly to the US. Any US leg of your trip is ticketed and operated by a different airline. Under standard interline practice, the carrier that issues the through ticket usually sets the baggage allowance for the whole itinerary.
The operating carrier of one segment does not decide that on its own. A Mexicana domestic segment booked inside a US connecting itinerary follows the rules of whichever airline sold the ticket. Confirm that with the ticketing airline.
Check US airport security rules separately if your connection routes through a US airport.
What travelers are actually reporting
Mexicana relaunched only in December 2023. The forums this site checks, frequent flyer forums included, carry almost no carrier specific baggage threads for it yet. That reflects a small, recent, domestic only operation, not a gap in this page’s research.
One pattern is still worth flagging from the airline’s own wording. It is the combined carry-on plus personal item weight cap. Travelers used to per bag limits on other airline pages often miss that detail.
The bottom line
Mexicana keeps its baggage rules short. There is a 10 kilogram combined cabin allowance, a 25 kilogram checked bag capped at 158 centimeters total, and a per kilogram overweight charge rather than a flat fee.
Pack light on the personal item, since it shares the same scale as your carry-on. Check your fare’s actual inclusions at booking, since Mexicana ties checked bag allowance to fare type.
For the rest of your packing plan, a baggage cost calculator can help you compare Mexicana airlines baggage fees against a checked bag bought in advance.
