KLM Carry-On: Basic Fare, Sizes and Combined Weight

Check the allowance on your ticket before packing. The small under-seat bag is 40×30×15 cm; each permitted overhead bag is 55×35×25 cm, including pockets, wheels and handles. These rules concern KLM-operated flights; check the operating airline on connections.

Allowance by fare and cabin

The weight covers all these items together, including the small bag. It is not 12 or 18 kg per suitcase. For example, a 10 kg suitcase plus a 3 kg small bag exceeds a 12 kg combined allowance. On departures from the United States, the published restriction is one overhead bag and one small bag, including in cabins that otherwise allow two overhead bags.

Basic is not the same rule as Light

Basic includes the small bag only; Light, Standard and Flex include one overhead bag. Where eligible, buy the Basic Hand Baggage option in My Trip up to 4 hours before departure. Valid Flying Blue Gold, Platinum and Ultimate members receive one overhead bag with Basic. Confirm your flight and status eligibility; buying the option does not guarantee cabin storage.

Measure size and check total weight separately

Measure the packed external dimensions. Our Basic checker or paid-cabin-bag checker assesses one bag; it does not add up the weight of multiple cabin items or determine your status and route exceptions. Weigh all cabin items together yourself. Use the route checker for dimensions across operating airlines.

Boarding, children and restricted items

A compliant bag can go in the hold free when bins are full. Confirm the return point; do not assume every Cityhopper bag returns at the aircraft door. Keep essentials and batteries accessible.

A lap infant may bring one 55×35×25 cm bag up to 12 kg. Children with their own seat follow their ticket allowance. One stroller/back carrier and one car seat or CARES travel free per child, subject to handling and cabin-use conditions. For stroller gate access, KLM’s detailed section and FAQ differ; confirm the arrangement.

The published liquid rule is containers up to 100 ml in a transparent closed bag up to 1 litre, with exceptions for necessary medicines, baby/special-diet food and sealed duty-free items. KLM permits at most two power banks and prohibits their use, charging and overhead-bin storage on board. Check battery capacity and approval rules.
