Which carry-on rules really apply in 2026?
The most important insight first: there is no single rule for all airlines. The international aviation association IATA recommends standard dimensions, but each airline decides for itself. However, in the first half of 2026, the European Parliament adopted a uniform regulation for the coming year: airlines operating in the EU must allow passengers to bring one piece of carry-on baggage free of charge.
For you, this means: if in doubt, check with your airline about the valid dimensions and weight limits for carry-on baggage. Especially with low-cost fares, in 2026 often only one small bag is free of charge.
What dimensions are common?
Many airlines follow the recommended guidelines of the aviation association. If your baggage falls within this range, you are usually on the safe side:
- approx. 56 × 45 × 25 cm as a standard size
- weight limit starts at 5 kg
- a small additional bag is usually allowed
How strict are weight restrictions?
Here as well: each airline has its own maximum carry-on weight. A few hundred grams difference is rarely an issue. However, note that significant excess weight can incur charges. On average:
- 8 kg carry-on baggage
- in some cases 10–15 kg possible
- depending on fare and booking class
- checks at the gate are common

What is allowed in carry-on — and what is not?
There are also guidelines regarding safety on board, specifying which items are allowed, prohibited, or potentially problematic. We show you what to consider so you can pass through security smoothly with your carry-on baggage.
Which liquids are allowed?
Even though more and more airports are introducing modern scanners that screen baggage using computed tomography, the well-known 100 ml rule still applies. This means that liquids may be carried in hand luggage if:
- each container holds a maximum of 100 ml
- all liquids are stored in a 1-liter bag
- the 1-liter bag is transparent
Exceptions are often made only for baby food, milk, and drinking bottles for babies and children up to 3 years old.
Which items are prohibited in carry-on baggage?
Uniform regulations apply to prohibited items. These items belong in checked baggage and are not allowed on board:
- knives and scissors with blade length over 6 cm
- tools such as screwdrivers
- sports equipment such as golf clubs, hiking poles
- flammable or hazardous substances
- weapons and replicas
What is allowed but sometimes tricky?
The following common travel items are often allowed but may be subject to closer inspection. In some cases, they may also be refused, for example if the blade is longer than 6 cm:
- tweezers usually allowed
- disposable razors unproblematic
- small nail scissors usually allowed
- loose razor blades sometimes problematic
- metal nail files sometimes problematic
Our tip: if you are unsure, it is best to put the item in checked baggage or ask in advance.
