Frequently asked questions

No, you don't need to buy a separate Brussels Airport Supplement for children under 12 years old:

  • Children under 12 years who accompany another traveller travel for free (Free4kids) do not need any ticket at all and do not have to pay the Brussels Airport Supplement. Accompanied children can pass through the gates at Brussels Airport-Zaventem station together with another passenger.
  • If your child is travelling alone with a Kids Ticket with Brussels Airport-Zaventem as departure or arrival station, the Brussels Airport Supplement is already included in the price of the Kids Ticket. You don't need to buy a supplement separately. Your child can open the gates at Brussels Airport-Zaventem station with the QR code that appears on his Kids Ticket.
An ID (or legal document) providing proof of the child's age is always required when travelling.
