From Brussels Airport there is a fast, direct connection to the main Brussels railway stations (Brussels North, Brussels Central and Brussels South). There is a direct train every 15 minutes in both directions. You arrive in the centre of Brussels in just 17 minutes. Every passenger travelling to or from Brussels National Airport has to pay a "Diabolo" supplement (5,70€) on top of the ticket price. The standard ticket price for travel between the airport and the Brussels Zone is €9,30 per day (return trip €18,60), which includes the Diabolo fee. If you already have an SNCB ticket, you will have to pay the Diabolo fee separately.
