Aeromexico Baggage Policy: Carry-On Sizes, Checked Bag Fees, and Weight Limits
Aeromexico applies distinct baggage allowance rules depending on your fare family (Tarifa Básica, Clásica, AM Plus, or Clase Premier) and your flight's geographic route. Cabin baggage is strictly regulated by a combined weight cap across both your personal item and carry-on suitcase. Travelers can save money by pre-paying for checked luggage online up to 24 hours prior to departure rather than paying higher rates at the airport ticket counter.
Aeromexico Baggage Policy Summary: Aeromexico permits one free personal item and one overhead carry-on bag for standard fares, capped at a combined weight limit of 10 kg (22 lbs) in Economy or 15 kg (33 lbs) in Clase Premier. Carry-on dimensions must not exceed 55 x 40 x 25 cm (21.5 x 15.7 x 9.8 in). Standard checked bags allow 62 linear inches (158 cm), with a weight cap of 25 kg (55 lbs) for domestic Mexico routes and 23 kg (50 lbs) for international flights. Tarifa Básica includes zero checked bags.

How BaggageBase Checks This Information
BaggageBase prioritizes published fare terms, airline policy manuals, conditions of carriage, and direct tariff filings. Aeromexico applies a combined weight enforcement model in the cabin and different checked baggage weight allowances between domestic Mexico and international flights. We explicitly separate these regional variations rather than using generic figures. Variable elements, such as dynamic seasonal checked bag fees or specific interline codeshare exceptions, require confirmation against your active booking itinerary.
1. Aeromexico Carry-On & Personal Item Policy
Aeromexico permits passengers across standard fare tiers to bring items into the aircraft cabin. Cabin baggage acceptance depends on strict dimensional limits and a single combined weight cap enforced across your belongings.
1.1 Overhead Carry-On Dimensions & Standards
The primary carry-on item intended for the overhead locker must not exceed 55 x 40 x 25 cm (21.5 x 15.7 x 9.8 in).
Official documentation does not explicitly detail whether external handles, wheels, and side pockets are included in these specific dimensions. Travelers should measure their bag including wheels and handles to ensure it passes check-in sizers. Checking that your bag complies with international carry-on size standards helps avoid unexpected gate-check penalties.
1.2 Personal Item Rules & Under-Seat Placement
In addition to your main carry-on bag, Aeromexico permits one personal item free of charge. Eligible personal items include:
- Purses and handbags
- Laptop bags and briefcases
- Small backpacks or tote bags
Your personal item must fit under the seat directly in front of you. Aeromexico does not list explicit numerical dimensions for personal items across every route chart, but the accepted industry standard for under-seat space is approximately 45 x 35 x 20 cm (18 x 14 x 8 in). Review our airline personal item size comparison to see how under-seat dimensions vary across international carriers.
1.3 Enforced Combined Cabin Weight Limits
Unlike many US domestic airlines that enforce weight limits only on checked luggage, Aeromexico enforces a combined cabin weight cap. Gate agents and check-in staff measure the combined weight of your overhead bag and personal item together.
- Economy Cabins (Básica, Clásica, AM Plus): 10 kg (22 lbs) combined total weight for both pieces.
- Business Class (Clase Premier): 15 kg (33 lbs) combined total weight for both pieces.
If your overhead bag weighs 8 kg and your backpack weighs 4 kg, your combined weight is 12 kg. In Economy, this exceeds the 10 kg limit, requiring one item to be checked. Read our airline carry-on size comparison guide to evaluate cabin weight allowances across global airlines.
| Cabin / Fare Class | Personal Item Allowed? | Overhead Carry-On Allowed? | Max Dimensions (Carry-On) | Enforced Combined Cabin Weight Limit |
|---|---|---|---|---|
| Tarifa Básica (Basic) | Yes (1 piece) | Yes (1 piece) | 55 x 40 x 25 cm (21.5 x 15.7 x 9.8 in) | 10 kg (22 lbs) combined total |

7. Before You Fly Checklist (Pre-Airport Preparation)
Aeromexico Packing and Baggage Checklist
Follow these practical steps to avoid unexpected baggage fees at the airport.
- Weigh carry-on items together. Ensure your overhead suitcase and personal item combined do not exceed 10 kg (22 lbs) for Economy or 15 kg (33 lbs) for Clase Premier.
- Verify your route's checked weight cap. Confirm whether your route permits 25 kg (55 lbs) for domestic Mexico flights or 23 kg (50 lbs) for international flights.
- Pay for checked bags online early. Pre-pay for checked luggage via Aeromexico.com or the app at least 24 hours prior to departure to get lower rates.
- Measure linear inches. Add Length + Width + Height to verify your checked bag is under 158 linear cm (62 in) including wheels and handles.
- Pack medical gear separately. Keep CPAP machines, medication, and lithium power banks in carry-on bags so they do not count against weight caps.
- Prepare a backup plan for heavy bags. If your checked bag weighs near 23 kg (50 lbs), bring a packable duffel to redistribute weight if needed at check-in.
