How does it work?

Either by scanning the barcode printed on their train ticket (paper or electronic versions), or by scanning their MoBIB card. If you are travelling to Brussels Airport-Zaventem station, it is important to keep your ticket handy to be able to access or leave the station easily.

  2. Hold your MoBIB card over the reader or scan the barcode on your ticket.

Practical info

Accompanied children under the age of 12 travel free and can pass through the gates with the assistance of the staff present. The same applies to those carrying a national discount card for the blind and partially sighted.

Specific gates are provided for persons with reduced mobility. Standard gates are regulated to allow one person through, but there is sufficient space to pass through with small objects and luggage.

It is still possible to take a connecting service at Brussels Airport-Zaventem station, without having to pass through the gates.

Please note that a member of staff will be present at all times. Our staff are available to answer any questions or respond to any problem you may have. Assistance posts are also available fitted with a call button, allowing you to contact ticket counter staff.

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.
*= If you are travelling to or from Brussels Airport-Zaventem with a Senior Ticket:
  • Your Seniors ticket contains a barcode that opens the gates at the airport and automatically includes the Brussels Airport Supplement for the outbound leg of your return journey. This Brussels Airport Supplement is automatically added once to the fixed price of your Senior ticket.
  • If you want to use your Seniors ticket for a return trip on the same day, you will have to buy an additional Brussels Airport Supplement for your inbound leg.
