Souleymane Enok
Traveling in 2026 means adapting to increasingly strict rules for carry-on luggage, as well as new habits related to comfort, technology, and airlines. Permitted dimensions, maximum weight, prohibited items, external batteries, liquids, computers, carry-on bags... there are many questions, and they evolve regularly. To avoid unpleasant surprises at the airport, it is essential to know the up-to-date rules and best practices. In this article, we answer 15 key questions about carry-on luggage in 2026, to help you travel with peace of mind, optimize your carry-on bag, and meet airline requirements, whether for a short trip or a long journey.
1. What are the permitted dimensions for carry-on luggage in 2026?
In 2026, the permitted dimensions for carry-on luggage still vary by airline, despite a desire for European-level harmonization. The most commonly accepted format remains 55 x 40 x 20 cm, including wheels and handles. This size corresponds to the standard carry-on bag that can be placed in overhead compartments. However, many airlines, especially low-cost ones, have tightened their rules and now clearly distinguish between free small carry-on bags and standard cabin bags.
The small carry-on bag, intended to be placed under the seat, generally has dimensions around 40 x 20 x 25 cm. The bulkier carry-on bag is often included only with certain options or priority fares. In 2026, inspections are more frequent, with sizing frames installed at boarding gates. To avoid any extra charges, it is essential to check the specific dimensions authorized by the airline before departure and choose luggage that complies with the strictest standards.
2. What is the maximum permitted weight for carry-on luggage in 2026?
The permitted weight for carry-on luggage remains a deciding factor in 2026, even if it is sometimes less visible than dimensions. On average, airlines allow a weight between 7 and 10 kg for a standard cabin bag. Some traditional airlines tolerate up to 12 kg, while low-cost carriers apply stricter limits, sometimes around 7 kg.
Failure to respect the maximum weight can lead to additional fees or the requirement to check the bag into the hold. In 2026, weight checks are increasingly frequent, especially on busy flights. It is therefore recommended to invest in a travel scale to avoid any bad surprises. Traveling light is becoming a real strategy, favoring lightweight and well-organized carry-on luggage capable of maximizing space without exceeding the imposed limits.
3. Can you have a handbag in addition to your carry-on luggage in 2026?
In 2026, the ability to have a handbag in addition to your carry-on luggage essentially depends on the airline's policy. Most airlines still allow one personal item in addition to the cabin bag, provided it can be placed under the seat. This can be a handbag, a compact backpack, or a laptop bag.
However, the dimensions of this item are strictly regulated. If the bag exceeds the permitted limits, it may be considered a second paid bag. Low-cost airlines are particularly vigilant on this point. In 2026, it is therefore recommended to choose a soft, low-volume, and easily compressible handbag. This combination allows you to carry your essentials within reach while complying with the rules at no extra cost.
4. Are liquids still limited in carry-on luggage in 2026?
Yes, in 2026, liquids in carry-on luggage remain subject to strict restrictions in the majority of airports. The rule of containers of 100 ml maximum, placed in a one-liter transparent plastic bag, is still widely applied. This regulation concerns drinks, gels, creams, perfumes, and cosmetic products.
However, some airports equipped with new security scanners are beginning to relax these rules. In these modern facilities, it is sometimes possible to carry larger quantities of liquids without taking them out of the luggage. Despite these developments, the classic rule remains the norm in 2026. To avoid any confusion, it is strongly advised to pack your carry-on according to traditional restrictions, unless clearly indicated by the departure airport.
5. Can you carry an external battery in your carry-on luggage in 2026?
In 2026, external batteries are still allowed in carry-on luggage, but strictly prohibited in checked baggage. Airlines apply precise safety rules regarding their capacity. Generally, batteries up to 100 Wh are accepted without special authorization. Those between 100 and 160 Wh may require prior authorization from the airline.
External batteries have become essential for travelers, but their transport is closely monitored. They must be protected against short-circuits and transported in an intact state. In 2026, it is recommended to choose certified models that comply with international standards and to keep them accessible during security checks. Non-compliance with these rules may result in the battery being confiscated.
6. Do computers and tablets still need to be taken out of carry-on luggage?
In 2026, the rule regarding computers and tablets depends heavily on the airport's equipment. In many traditional airports, electronic devices must still be removed from carry-on luggage when passing through security checks. This measure aims to facilitate the inspection of contents.
However, airports equipped with new-generation scanners now allow electronic devices to be left in the bag. These technologies are being deployed gradually but are not yet generalized. To avoid any delay, it is advisable to organize your carry-on bag so that your computer or tablet can be accessed quickly. In 2026, anticipation remains the best strategy for getting through checks without stress.
7. Are food items allowed in carry-on luggage in 2026?
Yes, solid foods are generally allowed in carry-on luggage in 2026. Snacks, sandwiches, dried fruits, and biscuits can be carried without difficulty, as long as they do not contain prohibited liquids. On the other hand, liquid or semi-liquid foods, such as soups, sauces, or yogurts, are subject to the rules on liquids.
It is important to note that the customs rules of the destination country may also apply. Certain fresh or animal-derived foods may be prohibited upon arrival. In 2026, taking a snack in your carry-on bag remains an excellent solution to avoid hunger during the trip, provided you respect safety restrictions and international health regulations.
8. Can you put medication in your carry-on luggage in 2026?
Medication is allowed and even highly recommended in carry-on luggage in 2026. Personal treatments should always travel with the passenger to avoid any problems in case of delay or lost checked baggage. Liquid medications exceeding 100 ml are allowed if they are accompanied by a prescription or medical proof.
It is advisable to keep medications in their original packaging and to bring a sufficient quantity for the entire duration of the trip. In 2026, security checks are understanding on this point, but presentation of supporting documentation may be requested. Keeping your medication in your carry-on bag ensures safety, comfort, and peace of mind.

9. Are sharp objects allowed in carry-on luggage in 2026?
Sharp objects remain strictly prohibited in carry-on luggage in 2026. Knives, scissors with long blades, traditional razors, and cutting tools must be placed in checked baggage. Only certain very specific items, such as scissors with rounded ends or short blades, may be tolerated according to local regulations.
Security checks are particularly rigorous on this point. Any object deemed dangerous can be confiscated without the possibility of recovery. To avoid any unnecessary loss, it is essential to check the contents of your carry-on luggage before departure. In 2026, the rule is clear: any object that could pose a security risk must be excluded from cabin baggage.
10. Can you travel with carry-on luggage only in 2026?
Traveling with carry-on luggage only is more of a strong trend than ever in 2026. Many travelers prefer this option to save time, avoid checked baggage fees, and limit the risk of loss. With good organization, it is quite possible to travel for several days with just a cabin bag.
This involves selecting versatile clothing, limiting footwear, and opting for compact formats. In 2026, the restrictions imposed by airlines make this practice more demanding, but also more strategic. The carry-on bag becomes a real tool for trip optimization, combining practicality, speed, and freedom of movement.
11. Are low-cost airlines stricter in 2026?
Yes, in 2026, low-cost airlines apply particularly strict rules regarding carry-on luggage. Dimensions and weight are checked with rigor, and the slightest excess can lead to high fees. The standard cabin bag is often paid, while only a small personal bag is included in the base fare.
This policy aims to optimize space on board and maximize ancillary revenue. For travelers, this implies meticulous preparation and perfect knowledge of the rules. In 2026, traveling with a low-cost airline requires being particularly vigilant about the choice of luggage and its contents to avoid any bad surprises at boarding.
12. Can you buy specific carry-on luggage for flying in 2026?
In 2026, buying carry-on luggage specifically designed for planes has become common practice. Many brands offer models perfectly adapted to the maximum dimensions authorized by airlines. These bags are designed to optimize every centimeter, with smart compartments and reduced weight.
Investing in compliant cabin luggage allows you to travel with peace of mind and avoid unexpected fees. In 2026, this type of luggage is almost essential for frequent travelers, especially those using low-cost airlines. A good piece of carry-on luggage becomes a real travel ally.
13. What happens if my carry-on luggage does not comply with the rules?
If your carry-on luggage does not comply with the rules in 2026, several scenarios are possible. The most common involves having to pay a surcharge to place the bag in the hold. In some cases, the luggage may be refused at boarding until the situation is rectified.
The fees applied are often high, especially when paid at the boarding gate. To avoid this inconvenience, it is essential to check the airline's rules in advance and measure your bag precisely. In 2026, tolerance is increasingly low, making preparation essential.
14. Will carry-on luggage rules still evolve after 2026?
The carry-on luggage rules are constantly evolving, and it is very likely that they will continue to change after 2026. European harmonization, the evolution of security technologies, and the commercial strategies of airlines heavily influence these rules. Travelers must therefore stay informed regularly.
Technological innovations, particularly in security checks, could eventually allow for a relaxation of certain restrictions. However, economic stakes suggest that airlines will continue to strictly regulate cabin baggage. In 2026, adaptability remains the key to stress-free travel.
15. How to avoid fees related to carry-on luggage in 2026?
To avoid fees related to carry-on luggage in 2026, the best strategy is to plan ahead. It is essential to know precisely the rules of the chosen airline, in terms of both dimensions and weight. Choosing compliant luggage, traveling light, and optimizing the internal organization of the bag are effective levers.
Opting for a small personal item when possible, or purchasing a baggage option in advance, often costs less than paying at the airport. In 2026, traveling smart means rigorous preparation, which allows you to save money while traveling with peace of mind.
