Aeromexico Carry-On Rules: Size, Personal Item & Baggage
Quick answer: Aeromexico generally allows one carry-on bag plus one personal item. The carry-on maximum is 55 × 40 × 25 cm (about 21.6 × 15.7 × 9.8 in). The combined weight allowance is tied to your fare and is commonly 10 kg or 15 kg for the two cabin items together.
Aeromexico carry-on allowance
- Cabin bag: 55 × 40 × 25 cm maximum.
- Personal item: one smaller under-seat item; Aeromexico recommends no more than 45 × 35 × 20 cm and 3 kg.
- Weight: verify the fare on your booking; published combined limits vary by fare.
Why the fare matters
The size rule is only part of the answer. Fare families can change the included cabin-item weight and checked-bag allowance. Open your itinerary and compare it with the current policy before packing; a cabin bag does not necessarily mean a checked bag is included.
Choose luggage with margin
A bag marketed as “22-inch” can exceed this rule once wheels and handles are measured. Start with our international carry-on luggage and under-seat personal-item bags.
