KombiTickets are offered by VVS in cooperation with many event organizers. Admission tickets, airline tickets, and so on, are recognized as VVS tickets in this special partnership offer. All KombiTickets are identified by a VVS stamp. Generally, KombiTickets are valid for the entire network for travel to the event as of 3 hours before the scheduled start of the event, and return travel until the end of operating hours (including night busses) on all VVS transit modes (2nd class). No additional transit ticket is needed. It is therefore advisable to purchase KombiTickets ahead of time. Information about advance sales locations for KombiTickets is available from the event organizer or the VVS.
