a short trip ticket (€2) is valid for one trip of up to six stops with bus or tram, or 3 stops on the U- or S-Bahn regardless of zones.
a single ticket (AB €3, ABC €3.80) is valid for two hours in one direction i.e away from your start point.
a 24 hour ticket (AB €8.80, ABC €10) is valid for 24 hours.
a 7 day ticket (AB €36, ABC €43), is valid for 7 days.
a monthly ticket (AB €86, ABC €107) is valid for four weeks and one day.
