Something for the kids ;-) This Saturday at the Cité Biblio...
Operators' ticket offices
Tickets can be purchased from operators' ticket offices (AVL, CFL, TICE), as well as from the Mobility Centre (Mobilitéitszentral).
Other points of sale
Lots of shops and business across the Luxembourg City sell bus tickets.
Outside the city, tickets can often be purchased at other points of sale (in particular post offices and bank branches).
