What are the new European standards for carry-on luggage?
Souleymane Enok
With the arrival of summer 2025, many European travelers are wondering about the new standards applicable to carry-on baggage. Authorized dimensions, maximum weight, rules on personal accessories, or even harmonization between airlines: the rules are evolving, and it is becoming essential to stay informed to avoid unpleasant surprises at the airport.
Until now, one of the main difficulties for passengers lay in the lack of uniformity between airlines. Each carrier applied its own rules, sometimes very strict, especially among low-cost airlines. These differences led to misunderstandings, additional fees, and stress at the time of boarding.
Faced with these recurring problems, European institutions have worked on a clarification and evolution of the standards related to carry-on baggage, with the aim of better protecting consumers, improving the legibility of the rules, and limiting certain practices deemed abusive. The new guidelines planned or applied in 2025 are part of this logic of transparency and progressive harmonization.
These changes concern both the guaranteed minimum dimensions, the distinction between carry-on baggage and personal accessories, and billing conditions. For both regular and occasional travelers, understanding these new standards has become essential to pack your carry-on bag in full compliance.
In this article, we will take stock of the new European standards for carry-on baggage in 2025, explain what is changing concretely for passengers, and help you adapt your luggage to travel without stress during the summer period.
New European standards for carry-on baggage in 2026
The new European standards for carry-on baggage, applicable progressively between 2025 and 2026, mark an important step for air travelers. The main objective of these changes is to clarify the rules, reduce abuse, and improve transparency between airlines and passengers, after years of heterogeneous and sometimes confusing practices.
A desire for harmonization at the European level
For a long time, each airline applied its own rules regarding carry-on baggage: different dimensions, variable weights, blurred distinction between carry-on baggage and personal accessories, and sometimes unpredictable fees. This situation has generated numerous misunderstandings and a sense of injustice among travelers.
The new European guidelines aim to establish a common foundation of rights for passengers, while leaving some room for maneuver for airlines regarding their commercial offers. The idea is not to impose a strict single model, but to set clear minimum standards.
Guaranteed minimum dimensions for carry-on baggage
One of the major points of the 2025–2026 standards concerns the recognition of a "reasonable" carry-on format, inspired by previous European court decisions. The texts confirm that carry-on baggage respecting standard dimensions cannot be charged as an optional service, provided it is luggage that meets safety requirements.
Even if airlines can still offer paid options (priority, extra baggage, larger formats), the principle is now clear: a carry-on bag of a reasonable size must be included in the ticket, without hidden surcharges.
Clarification between carry-on baggage and personal accessories
Another important step forward: the clearer distinction between carry-on baggage and personal accessories. The new standards encourage airlines to communicate clearly on:
- what constitutes a primary carry-on bag,
- what is considered a personal accessory (handbag, laptop bag, small backpack),
- and the dimensions associated with each.
This clarification aims to avoid arbitrary interpretations at the time of boarding, which are often sources of unexpected fees.
Increased transparency on potential fees
European standards also strengthen price transparency obligations. Airlines must now clearly inform, from the time of booking, of conditions related to carry-on baggage: accepted dimensions, maximum weight, and any potential supplements and options.
The goal is for the passenger to know before purchase what is included or not, and to be able to compare offers on a fair basis, without nasty surprises at the airport.
Progressive application according to airlines
It is important to note that these standards do not mean an immediate and total uniformity. Their implementation is progressive, and some airlines are adapting their policies faster than others. However, the European legal framework strengthens the position of passengers in the event of a dispute.
From 2025–2026 onwards, travelers will therefore have firmer foundations to challenge abusive fees, especially when their luggage respects the announced standards.
What this changes concretely for travelers
For passengers, these new standards imply:
- less ambiguity about what is allowed in the cabin,
- better cost predictability,
- a reduction in unexpected fees,
- and greater legal security in case of disagreement.
- This also encourages travelers to choose compliant carry-on bags, designed to respect standard European formats.

Why did the European Union want to change the rules on carry-on baggage?
The European Union wanted to change the rules on carry-on baggage to address issues that had become recurring for air travelers. For years, the absence of a clear and harmonized framework left room for practices that varied greatly by airline, generating misunderstanding, frustration, and unexpected fees for passengers.
One of the main drivers of this evolution is the lack of uniformity in the rules. Each airline applied its own dimensions, authorized weights, and distinctions between carry-on baggage and personal accessories. This diversity made trip preparation complex, especially for passengers using multiple airlines or making connections. The European Union therefore sought to establish a common base, which is more readable for consumers.
Another major issue concerns fees deemed abusive. Many travelers were being charged supplements for luggage that was nonetheless reasonable and compliant with the historical standards of air transport. These practices led to a multiplication of disputes and complaints to consumer protection authorities. By changing the rules, the European Union aims to better regulate these situations and limit unexpected costs.
The question of price transparency also played a central role. Too often, conditions related to carry-on baggage were only specified at an advanced stage of booking, or even at the airport. The evolution of the rules aims to force airlines to clearly inform passengers from the time of ticket purchase, so that they can compare offers on a fair basis.
The European Union also relied on several court decisions recalling that a carry-on bag of a reasonable size is an integral part of air transport. These decisions highlighted the need for a more explicit regulatory framework to avoid divergent interpretations.
Finally, this evolution responds to a broader desire for protection of passenger rights. By clarifying the rules on carry-on baggage, the European Union seeks to strengthen consumer confidence, improve the travel experience, and reduce conflict situations between airlines and travelers.
In summary, the European Union has changed the rules on carry-on baggage to harmonize practices, limit abuse, strengthen transparency, and better protect passengers against rules that were previously too vague.
What are the rights of passengers in the event of a dispute over carry-on baggage?
In the event of a dispute over carry-on baggage, passengers have clear rights, reinforced by European regulation and case law. These rights aim to protect travelers against abusive fees, unjustified refusals to board compliant luggage, and the lack of transparency from airlines.
First of all, a fundamental principle applies: a carry-on bag of reasonable size is an integral part of air transport. Several European court decisions have confirmed that an airline cannot charge a supplement for carry-on baggage that complies with safety requirements and the reasonable dimensions announced. If your bag respects the rules communicated during booking, you have the right to challenge any additional billing.
In the event of a disagreement at the airport, the passenger can request written justification for the supplement or the refusal of the luggage. This proof is essential for any subsequent steps. It is also recommended to keep the boarding pass, the booking confirmation, and any communication related to baggage conditions.
If the dispute persists, the traveler can file a written claim with the airline. The airline is required to respond within a reasonable time. If the response is unsatisfactory or absent, the passenger can contact a mediation body or a national consumer protection authority.
In the European Union, passengers can also rely on rules related to price transparency. If the conditions concerning carry-on baggage were not clearly indicated at the time of ticket purchase, the airline may be at fault. Lack of information constitutes a strong argument in favor of the consumer.
Finally, as a last resort, it is possible to take legal action or use online dispute resolution platforms provided by the European Union. These mechanisms are designed to facilitate procedures without immediately starting heavy legal processes.
In summary, in the event of a dispute over carry-on baggage, passengers have the right to transparency, to challenge unfair fees, to file a formal complaint, and to regulated avenues of recourse. Knowing these rights allows you to travel with greater peace of mind and avoid being subjected to unjustified practices.
