Children can travel alone from the age of five.

When booking tickets, you must state that the child/children is/are travelling alone.

A self-declaration form must be completed upon departure. It must also include the name, address and phone number of the person collecting the child/children at the destination. The travel information must be visible for the entire duration of the trip.

Children from the age of five up to the age of twelve require an escort to the departure gate. With an escort pass, one guardian can accompany children travelling alone on domestic flights all the way to the aircraft. Escort passes are issued by the check-in staff upon presentation of identification including a picture. Request an escort pass when checking in your child. On arrival, guardians wait for the children outside the baggage hall. It is required that those picking up children travelling alone present identification and that they are the same as those indicated on the form submitted upon departure. If the child needs to change planes during the trip, the airline will take care of the child.

If siblings or other children are travelling together and are to be exempt from these rules, the oldest child must be above the age of sixteen if the youngest is between the ages of five and twelve.

Prams are considered to be special baggage–proceed as follows:

1. The pram is checked in at the counter or using a machine in the normal manner. You receive a separate baggage check for the pram.
2. The pram must then be taken to the check-in counter for special baggage where you will be given a plastic bag to protect the pram.
3. The baggage check must be attached to the outside of the plastic bag so that it is clearly visible.

Note: Pushchairs (collapsible prams) may in certain cases be brought along as hand baggage, but note that this is at the airline's discretion. Check with your airline in plenty of time before departure.

There are a number of loan prams at the airport, which may be found after the security checkpoint in the gate areas.
Car seats and travel cots are also considered special baggage and must be checked in in the same manner as prams.

The main rule is that liquids are not permitted in hand baggage. You are nevertheless permitted to bring food and drink for children as long as the child is below the age of 2. Food containers may contain more than 100 ml and are not required to be packed in transparent sealable plastic bags in accordance with the rules for other liquids.

You must be prepared to taste the contents at the security checkpoint (to prove that it actually is children’s food. We recommend that you keep children’s food easily available in hand baggage and to present it when you pass through the security checkpoint.

Persons below the age of 16 travelling with adults are not required to present their own ID cards on domestic flights. Note: Some airlines have a 12 year age limit, check your airline before travelling.

If you are a Norwegian citizen, you can travel without a passport between the 15 member countries of the Schengen Agreement. It is nevertheless best to bring your passport when travelling outside the Nordic countries. For Norwegians, the only approved proof of identification outside the Nordic area is a passport.

If you travel outside of the Schengen area you must ensure that children have their own passports or that they are included in your passport. This can be arranged with the police.

If you require a visa, this may also be required of children. Certain countries require separate applications for children even though they are travelling with adults holding visas.
