flying with children & pets - Spanish nationals
Spanish residents children aged under 18 years who are travelling without their parents/legal guardians on a valid EEA issued national identity card on flights between European Economic Area (EEA) countries must have a form (collected from their local police station) of written authorisation to travel from their parents. This form will need to be presented at the check-in desk and passport control. They will be unable to board the flight without this form. Note: This does not apply to UK and other foreign nationals departing Spain.
