What baggage can you take on board your KLM flight?

KLM allows different types of baggage in the cabin. You can usually take one piece of carry-on baggage, such as a suitcase or backpack, plus a small personal item, for example, a handbag or laptop bag. It is important to know these rules because they ensure sufficient space and safety on board. The distinction between a small bag and carry-on baggage helps you pack efficiently and keep your belongings easily accessible during the flight.

Maximum carry-on dimensions for KLM

Standard carry-on baggage on KLM can be a maximum of 55 x 35 x 25 centimeters, including handles and wheels. Additionally, it is permitted to bring a small personal item with dimensions up to 40 x 30 x 15 centimeters. These measurements always include the outer dimensions, so measure your suitcase including wheels and handles to avoid surprises. Tip: carefully measure your carry-on baggage at home with a tape measure before packing.

Carry-on weight limits per travel class

The weight of your carry-on baggage depends on the travel class and ticket type. In Economy Class, the total weight of your carry-on baggage and small bag may not exceed 12 kilograms. Business Class passengers can often take up to 18 kilograms, divided between carry-on baggage and personal items. Weight limits are crucial for safety and ensure that all passengers can travel comfortably without overloading the overhead bins.

Number of permitted carry-on items per class

Economy Class passengers can usually bring one carry-on suitcase and one small personal item. With a Basic ticket, carry-on baggage may not be included for free. Travelers in Premium Comfort and Business Class can usually bring two pieces of carry-on baggage plus a personal accessory. These differences reflect the varying comfort levels and costs per ticket type.

What items can you bring in your carry-on baggage?

Liquids in carry-on baggage are limited to containers of maximum 100 ml each, and these must fit together in a transparent, re-sealable plastic bag of maximum 1 liter. Prohibited items include weapons, dangerous chemicals, and larger lithium batteries. Duty-free purchases can be taken on board if they are sealed and you are transferring to an international flight. Electronics and e-cigarettes have special rules, so check these per destination.

Carry-on rules for babies and children

For babies without their own seat, you may bring one piece of carry-on baggage of maximum 55 x 35 x 25 cm and 12 kg, plus baby food. Babies with their own seat follow the same carry-on baggage rules as adults. Children aged 2 and older may bring the same amount of carry-on baggage as adults. Additionally, strollers and car seats can usually be taken or checked in for free.

KLM carry-on in difficult situations: too large or too heavy

If your carry-on baggage is too heavy or too large, KLM may ask you to check it in as checked baggage, which often incurs additional costs. Carry-on baggage that does not meet the maximum dimensions will not be allowed in the cabin. To avoid problems, it is best to weigh and measure your bag at home beforehand and, if necessary, book extra baggage online. Plan your carry-on baggage carefully and take into account differences per flight and airport.

Bringing carry-on baggage on fully booked flights

On full flights, KLM may check carry-on baggage for free at the gate. Always make sure you have a small bag with essential items that you can easily keep with you. Keep yourself well informed by KLM about specific procedures for your flight, so you are not faced with surprises.

Overview of carry-on rules per KLM ticket type

KLM applies different rules per ticket type. Basic tickets often do not include free carry-on baggage, and extra costs may apply. Light and Standard Economy usually offer one piece of carry-on baggage plus a small item. Flex Economy and Premium Comfort give higher weight and piece limits. Business Class passengers can generally bring the most. Always check your ticket conditions carefully to avoid unpleasant surprises.

Liquids and special items in carry-on baggage with KLM

Liquids can be carried in hand luggage if they are in containers of maximum 100 ml, together in a transparent bag of maximum 1 liter. Medical necessities, baby food, and electronic cigarettes have separate rules and are usually allowed if declared. Security checks will be strict on these. Since rules differ per airport, it is wise to check the current information just before departure.

Paid carry-on baggage on European KLM flights

From July 1, 2025, KLM will experiment with paid carry-on baggage on some European routes. Tickets such as Basic will then often no longer include free carry-on baggage. Tickets with a carry-on baggage exemption will continue to exist, but extra pieces of carry-on baggage will incur surcharges. This measure helps KLM to board faster and reduce congestion during busy flights.

Tips for choosing suitable carry-on baggage for KLM

Choose a carry-on suitcase or backpack that fits within the maximum dimensions of 55 x 35 x 25 cm. Convenient options include a compact trolley with a TSA lock, a lightweight backpack, or a sturdy laptop bag. Make sure the weight remains as low as possible and that the bag is easy to maneuver. Popular models that meet KLM dimensions can be found, for example, in our selection of Carry-on Suitcases. For these, lightweight options with silent wheels are also recommended.

Where to place carry-on baggage during the flight?

Your small bag should always be placed under the seat in front of you. The carry-on suitcase goes in the overhead bins above your head. At emergency exits, there are sometimes additional rules, usually determined by the cabin crew. Always follow the instructions for placing your baggage for your own safety and comfort.

Security rules and carry-on baggage control at KLM

At the airport, your carry-on baggage will be checked for weight, dimensions, and prohibited items. Sometimes bags are extra checked if there is doubt about the contents. Pack your carry-on baggage smartly and keep liquids separate for faster inspection. By knowing and applying the rules at home, you prevent delays during the security check.

Carry-on baggage when transferring and customs control

When transferring, your carry-on baggage may be scrutinized more closely, especially duty-free purchases must be sealed. Customs regulations differ per airport and country, which can cause surprises. Prepare your carry-on baggage well for this and take local regulations into account to avoid problems.

Booking extra carry-on baggage and checked baggage with KLM

If your carry-on baggage is too large or too heavy, it must be checked in as checked baggage at an additional cost. You can book checked baggage via My Trip up to 24 hours before departure, which is often cheaper and easier than at the counter. Checked baggage offers more comfort, so you can travel without worries. Compare prices and book early to save costs.

Important final tips for packing carry-on baggage for KLM

Pack your carry-on baggage efficiently and adhere to the rules for dimensions and weight. Check the weight at home with a scale to avoid surprises. Make sure your small bag only contains essential items for use during the flight. Always consult the official KLM website for the most up-to-date carry-on baggage rules just before departure.
