On national routes, at the time of boarding, the responsible adult must accompany the minor, who will carry the ticket along with a copy of the Authorization Document or Kangaroo Service signed by the legal guardian and previously confirmed by our Customer Service. To obtain this documentation confirmation, parents or guardians must have sent the signed validation request through this form with a minimum of 48 hours' notice before the departure time of the journey (in spanish).

Our drivers are not authorised to allow any child aged 4-14 on board unless their forms are validated by Alsa.

Authorisation forms:

  • One-off authorisation: allows a minor to board a specific service once. It is valid only for the specified journey.
  • Temporary authorisation: for children who frequently travel alone. It is valid for at most one year, for a specific route.
