Travelling (with) children

We enjoy keeping our young passengers and their parents happy. If you have a child aged between 5 and 14 years old who is travelling alone, then you are required to book our Unaccompanied Minor service.

Travelling with your child

Children up to and including 14 years of age must always be accompanied by a person aged 18 years or older who will bear responsibility for the child throughout the trip. In addition, the child must travel together with their parent or guardian on the same flight and in the same travel class, unless the Unaccompanied Minor service has been booked.

Children of European Union citizens (age 0-15 years) travelling from, to or through countries in the European Union may carry their own passport or travel with the parent’s passport, if the child is registered in it. If the child travels with the document of his parent or legal guardian, it’s important they have the same nationality. This rule does not apply to nationals of Bulgaria, Croatia, Cyprus, Romania and Schengen member States.

If travelling to or from Thailand, children aged 16 years and younger travelling alone or with 1 parent only, need to bring a copy of their birth certificate, and a letter of consent to travel from the non-travelling parent/parents.

For travel to and from South Africa as of 1 June 2015, all children need to bring various documents – regardless if they travel with both parents, with 1 parent, with an accompanying adult or alone. Read more about the new rules for travel to/from South Africa

Some countries may require additional documentation for travelling children.

Children travelling alone

Child with adult
  • Children up to and including 4 years of age may only travel when accompanied as described above.

  • Children aged 5 to 14 years old may travel alone if the Unaccompanied Minor service has been booked. This service is mandatory for children in this age group who are travelling alone. You can book this service via KLM Telephone Reservations.

  • Children aged 15 to 17 years old may travel alone on AIR FRANCE and KLM flights only. However, if you prefer you may book the Unaccompanied Minor service for your child in this age group.

All children travelling alone to or from Curaçao (including children aged between 16 and 18 years old for whom no Unaccompanied Minor Service has been booked) need to bring a written confirmation that they are allowed to travel, signed by parent/parents or legal guardian, and a copy of an identification document of a parent or guardian.

Other airlines may have other rules for children travelling alone. Please check with your travel agent or contact the airline your child will be travelling with.

Junior Jet Service

Young children – and their parents – can always count on extra care and special extras. Play packages and various items for babies are available on all KLM intercontinental flights.

Travelling with children younger than 2

A child younger than 2 years of age on the outbound journey and on the inbound journey may travel sitting on your lap. All children who turn 2 years or older before or during the inbound journey need to have his/her own seat reservation for both the outbound and inbound journeys.

Although 1 adult may accompany a maximum of 2 babies, only 1 baby may sit on his/her lap. The other baby will require a seat of its own.

Children’s meals
On intercontinental KLM flights, we have a limited number of sterilized meals available for infants and toddlers up to 2 years. You don't need to order these meals upfront. However, we recommend always bringing your baby’s food yourself. Any restrictions on bringing liquids do not apply to baby food.

Carrycots can be reserved for babies on intercontinental flights, via My Trip or by calling KLM Telephone Reservations. These are suitable for babies who are no longer than 65 cm and weigh no more than 10 kg on the day of the trip. Although we’ll do our very best, we cannot always guarantee the availability of a carrycot when you board the aircraft.

Baggage, buggies and child seats


Children travelling in their own (booked) seat may bring the same amount of hand baggage and check-in baggage as an adult.

For a child younger than 2 years of age who will be travelling on your lap, you may bring:

  • 1 piece of hand baggage with baby care items weighing max. 12 kg (26 lbs) and with dimensions not exceeding 55 x 35 x 25 cm (22 x 14 x 10 in).
  • 1 piece of check-in baggage of max 10 kg (22 lbs). If your child’s baggage is carried in one of the parents’ check-in baggage, this baggage may weigh no more than 23 kg (50.5 lbs) per piece.

For each child you may always bring 1 small, completely collapsible stroller/pram free of charge.

If the stroller will not fit under the seat or in the overhead baggage compartment, you can check it in at no extra charge.

The stroller/pram may have a protective cover but this may not contain any other items.

Car/child seats
For each child you may always bring 1 car/child seat free of charge. If you have reserved a seat for your child, we recommend that you bring your own car/child seat on board.

  • The car/child seat must be able to fit between the armrests of the aircraft seat, which is 42 cm (16.5 in) wide.
  • Your child and the child seat need to be secured according to the seat manufacturer’s instructions.
  • A child seat may show no defects and must be approved for air transport and marked accordingly.
  • You need to reserve for the use of a car/child seat in advance. Please contact KLM Telephone Reservations or your local KLM ticket office.

You may also check in the car/child seat free of charge, in which case above rules do not apply.

Child Aviation Restraint System (CARES)
If you have booked a seat for your child, you may also bring a Child Aviation Restraint System for use on board:

  • Your child and the CARES need to be secured according to the manufacturer’s instructions.
  • The CARES may show no defects and must be approved for air transport and marked accordingly.
  • You need to reserve for the use of your CARES in advance. Please contact KLM Telephone Reservations or your local KLM ticket office.

Some of our partner airlines have different baggage rules to our own. Please contact your travel agency or the airline concerned for further details.
