Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
KLM Royal Dutch Airlines liquids policy
Published rule: 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. Check departure and connection security rules.
Family & Infants
Infant (under 2)
A lap infant aged 0–23 months may bring one cabin item up to 55×35×25 cm and 12 kg plus baby food for the flight. Basic/Light include no checked bag for the infant; other ticket types include one up to 10 kg. No fixed infant ticket price is modeled.
Stroller
One buggy, stroller or back carrier per child travels free. Size, folding, weight and aircraft restrictions determine gate/cabin access. KLM Cityhopper places strollers in the hold; arrival return depends on airport. The official detailed section and FAQ differ on large-stroller gate access: confirm with KLM rather than assume a gate guarantee.
Car seat
One car seat or CARES per child travels free. Cabin use requires a reservation up to 48 hours before departure, a booked seat and applicable certification/fit conditions. Car seats are not permitted in Boeing 787 Business Class. Otherwise arrange hold carriage.
Children's allowance
Children and infants with their own seat receive the baggage allowance of their ticket.
