In general, on national routes, children under 14 must always be accompanied by a responsible adult. On international routes, children under 16 may travel only when accompanied by an adult.

In exceptional cases, children aged 4-14 may travel alone on national routes, under the following conditions:

- Babysitter Service, available exclusively on Alsa Premium services: Alsa offers a Babysitter Service whereby an attendant supervises the child on the route and at all stops along the way. This service must be reserved at least 24 hours before travelling. Conditions:

  • This babysitter service is free of charge.
  • The adult accompanying the minor on boarding will be asked to show some form of ID for the child (ID card, family record book, etc.).
  • This adult will also be required to supply their name and telephone number, to be contacted by ALSA in the event of an incident.
  • If the child is on medication, the attendant will not be responsible for ensuring they take it.
  • On arrival at the destination, the adult picking up the child will be required to show some form of ID (ID card, passport, driving licence, etc.).
