Departures from Spanish airports
Entry through to the boarding area is permitted to guardians or family members of minors under 14 who are travelling alone for departures from airports in Spain. Please ask for a Companions’ Card at the Iberia check-in desk. They will only be allowed access to accompany the minor to the boarding gate on the day and time of the flight. The adult companion should carry his/her valid passport or national identification card to pass through border control with the minor.
Identification on international flights
On international flights (European and other countries), as there is no standardised regulation, all minors (travelling accompanied or unaccompanied, regardless of their age) must present their own document, national identification card or passport, in addition to complying with the requirements of the destination country.
If they travel alone and do not have a Passport, the DNI must be accompanied by a Parent or Guardian Authorisation formalised in a Police Department.
Flights to Mexico
All minors who travel to/from Mexico alone or accompanied by a third person who is not either their parents or their legal guardian should present a document signed by both parents or the parent who has custody or the person who has guardianship before a notary public or pertinent authority where it states that the child is allowed to leave the national territory. When it is a document granted abroad, it should be authorised or apostilled, depending on the case, with a translation (if in a language other than Spanish). In the specific case of Spain, the Police have an authorisation document for these cases.
Flights within the United States
Within the territory of the United States children up to 14 years of age are considered minors and they must fly with an accompaniment service.
