This year, American Airlines has implemented significant changes to its carry-on baggage rules that have taken those who regularly travel within the United States by surprise. Following what is already happening in Europe, the airline is unifying criteria and streamlining the boarding process, although many passengers are confused by the new restrictions.
New dimensions for cabin luggage
The most important new feature, effective from the beginning of 2025, is the adaptation of the maximum dimensions allowed for cabin baggage. Suitcases must now fit a size of 56 x 36 x 23 centimeters (22 x 14 x 9 inches), including wheels and handle. This initiative, inspired by European Union standards, aims to optimize space in overhead compartments and avoid problems with oversized items.
For many, this has meant a farewell to their usual carry-on, as the authorized measurements could leave out traditional suitcases used on domestic flights. However, American Airlines clarifies that, in the event of exceeding these restrictions, passengers will not be obliged to pay surcharges, but will have to check their baggage in the hold at no additional cost. Even so, the possibility of having to wait for a suitcase upon landing is a source of concern and annoyance for some travelers.
The personal item, a must-have accessory
In addition to the carry-on bag, there is still the option of carrying a personal item that must fit under the front seat. The measurements for this item cannot exceed 45 x 35 x 20 centimeters (18 x 14 x 8 inches). These are small bags, briefcases, compact backpacks or laptop sleeves. The airline clarifies that some items, such as child safety seats, folding strollers and medical or mobility devices, are not considered baggage and can be carried without inconvenience.
This measure aims to ensure that travelers have essential or valuable belongings on board, while larger items are accommodated in the overhead compartment. Each passenger is still entitled to only one carry-on baggage item and one personal item, so if you plan to travel with more items, you will have to check them in.
The case for American Eagle-operated flights
Those traveling on smaller aircraft, typically used on regional routes under the American Eagle brand, have encountered additional restrictions. Given the limited overhead bin capacity on these aircraft, any carry-on baggage that exceeds the dimensions of a personal item is tagged at the gate and stored in the hold. In this way, the company seeks to streamline passenger check-in and check-out by returning bags to travelers as they exit the aircraft, usually at the same gangway.
Limits for liquids and restricted items
Regarding items allowed in the cabin, the regulations stipulated by the Transportation Security Administration (TSA) are maintained. Each traveler may carry liquids, gels and aerosols in containers of up to 100 milliliters (3.4 ounces), always contained in a transparent, resealable bag. For example, toothpaste, shampoo and creams must comply with this rule or they must be checked in the checked bag.
Exceptions include medicines or baby food, provided they are declared at the security checkpoint. Any product that exceeds 100 ml and is not properly accounted for may be detained by TSA agents. Also, sharp objects such as scissors, razors or sharp tools remain prohibited in carry-on baggage, maintaining a long-standing regulation to ensure in-flight security.
Seeking harmonization with Europe
The adoption of the European measures was no accident. In recent years, several U.S. airlines have shown an interest in aligning their policies with those of the European Union, where the 55 x 40 x 20 centimeter limit has been a standard on numerous commercial flights. Although American Airlines has slightly adjusted these dimensions to 56 x 36 x 23 centimeters, the goal is to eliminate discrepancies and facilitate international travel, so that passengers do not have to adjust their luggage every time they cross the Atlantic.
Confusion and uncertainty among passengers
Although the airline insists on the long-term benefits of the measure, many travelers have expressed concern about the lack of clear information before it came into force in 2025. The coincidence of stricter rules with the habit of many to carry larger suitcases raises questions about what happens on high-demand flights or at holiday times, when planes are packed to capacity. In addition, some regret not having been informed in advance to renew their bags or plan their next trips for the year.
What you need to know now that it’s 2025
If you already have a flight scheduled for these months or plan to book your vacation at a later date, consider these recommendations:
- Check the dimensions of your luggage before going to the airport.
- Take advantage of your personal item to carry electronic devices and valuables.
- Remember that regional flights may have additional limitations, especially on smaller aircraft.
- Learn about the regulations for liquids and aerosols to avoid mishaps at the security checkpoint.
- Check the TSA and American Airlines websites for specific details, especially if you are traveling with special medication or baby food.
A change for the better or a source of confusion?
With the implementation of these rules during this 2025, American Airlines seeks better use of cabin space, reduce boarding delays and adapt to global standards. However, the success of the measure depends, in large part, on the clarity of communication and the ease with which passengers adopt the new bag sizes. While some celebrate the greater uniformity with Europe and the promise of avoiding extra costs, others fear that the initial confusion will affect their travel experience.
In either case, it pays to stay tuned for official updates and check airline information channels. Although 2025 marks the beginning of this regulation, adjustments are likely to occur throughout the year. For now, the main recommendation is to take nothing for granted and check ahead of time what you can and cannot take on board. After all, no one wants any last-minute surprises just before takeoff.
