Platform D of the bus station — since 7 May 2026 a temporary one, about 100 m from the terminal on level 0, under a covered walkway

You are paying EUR 7.90 for a journey that costs EUR 2.40 in the other direction. That is not a mistake on the fare machine — every ordinary STIB ticket is written to be void leaving this airport.

It is the best option for the European quarter: Schuman in about 27 minutes puts you where neither the cheap bus nor the train leaves you.

Paper costs EUR 0.50 more than contactless or a card.

Seven of you should still buy singles. The 10-journey card only wins from eight once the EUR 6.00 MOBIB card is counted, and from seven if you already have one.

Peak traffic nearly doubles it — 52 minutes to Trone against 38 off-peak.

WEEKDAYS ONLY, in the base timetable. On a Saturday or Sunday change at Brussel-Noord — about 43 minutes in all — or take De Lijn bus 91, which runs seven days a week.

Thirteen minutes, one stop, no Brussels: it is the fastest thing this airport does.
