If the minor is travelling within Spain
They must carry express authorisation (not subject to an official format) from their parents, the absent parent, or the person legally exercising parental authority.
However, the internal regulations of some airlines may also stipulate that it is necessary to show the family record book. We recommend that you contact your airline to confirm the documentation that you may need.
If the minor is travelling abroad
Spanish minors travelling alone or accompanied by a single parent, or by third persons who do not have parental authority, must have the following documentation:
Once the permit has been filled in and printed, you must go to a National Police station or a Civil Guard post. However, such declarations can also be issued, on whatever form they decide, by the police forces of the autonomous regions which are responsible for the protection of people and property and maintaining public order.
It is only necessary for one of the minor’s legal representatives to appear, as long as he or she has parental authority, legal capacity and the consent of the other parent, or the third person providing the details.
For their identity to be checked, they need to take their current identity document (DNI or passport) and the documentation proving the minor’s filiation and parental authority (DNI , passport and family book, etc.).
This authorisation is valid for 90 days.
In the case of foreign minors who are resident in Spain, their legal representatives or others, depending on the provisions of their respective national regulations, must go to their consular authorities to fill in the appropriate documentation in accordance with their national legislation.
Most airlines offer an assistance service for minors aged 5 to 12 who are travelling alone (this service may have an additional cost). The people responsible for the minor must sign a Waiver of Liability and guarantee that another adult will take charge of the minor at the destination airport.
From the moment that the minor receives their boarding pass, the airline becomes legally responsible for them. The minor will receive a bag they must carry containing:
As a general rule, minors will be accompanied out of the plane last, accompanied by airline personnel.
After collecting their baggage, the minor is handed over to the person responsible, after this person’s identity has been verified.
