EUR 11.90 on a weekday, with the EUR 6.90 supplement inside it: only 30 cents more than the ticket to Bruxelles-Central, for a train that goes the other way.
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.
Children under 12 travel free with you and pay no supplement; they walk through the gates with you.

EUR 3.00 against EUR 11.90 on the train, and the only direct way to Leuven at weekends, when the base rail timetable has no Leuven train.
It takes about an hour against the train's 13 minutes, and up to 85 in the morning peak.
The ticket is valid 60 minutes and the ride can take longer; De Lijn lets you finish the ride you are on, so a single bus is fine. Do not plan a change on the same ticket.
The last weekday bus is 21:17, well before the last train; on Saturday it is 22:18 and on Sunday 22:21.
Eight or more of you should buy one EUR 22 ten-ride card and scan it once per person.
The guides still name buses 651 and 652: De Lijn closed both on 6 January 2024. Line 91 from platform B is the bus.
