Aeromexico cabin bag dimensions and bag size

The maximum Aeromexico cabin bag size is 21.7 x 15.7 x 9.8 inches, which works out to 55 x 40 x 25 cm. These measurements include wheels, handles, and any external pockets. Gate sizers on Aeromexico match the published limits closely, so a bag marketed as "22 inch" can fail if its wheels push the total past 21.7 inches. Always measure your bag packed, not empty.

Aeromexico cabin bag weight limit

Aeromexico limits carry-on bags to 10 kg (22 lb). Most domestic check-in counters do not weigh carry-ons, but gate agents can pull bags that look heavy. If your bag is over the limit, expect to be asked to check it, sometimes at a higher gate-check fee.

Does Aeromexico charge for cabin bag bags?

No. Aeromexico includes a free carry-on bag plus a free personal item on most fares. The exception is Basic Economy, where some routes restrict you to a personal item only. Check your specific fare rules before you book.

Avoiding gate-check on Aeromexico

Aeromexico gate agents frequently weigh cabin bags on full flights, so if your carry-on plus personal item is near 10 kg, consolidate into one piece and put the heaviest items in the personal item.

Common Aeromexico carry-on mistakes

  • Assuming the 10 kg allowance is per bag. It is a combined total for carry-on plus personal item in Economy.
  • Treating Basic like a US basic economy fare. Aeromexico Basic still includes a carry-on; the catch is the checked-bag restriction, not the cabin.
  • Ignoring kg limits because you are used to US carriers that only size-check.

Aeromexico vs Volaris carry-on

Aeromexico is the friendlier Mexican option for carry-on. Every Aeromexico fare, including Basic, includes a 55 by 40 by 25 cm carry-on plus personal item at a combined 10 kg. Volaris restricts its cheapest Zero and Basic fares to a personal item only, forcing you up to Plus or to pay a la carte for the overhead bag. Volaris allows a heavier combined cabin load of up to 20 kg on Plus, but you pay for the privilege, and gate fees for an unticketed carry-on can reach MX$1,200 domestically or around USD 140 on US routes.

Ways to skip the Aeromexico checked bag fee
