STOAG tickets valid until March

From January 1st, new prices will apply in the Rhein-Ruhr transport association. Tickets that were purchased in 2016 are still valid until March 31, 2017. This applies to all single, 4-trip, day, 10-trip and additional tickets. If these tickets have been purchased from STOAG, they can also be exchanged for tickets with the new tariff in all STOAG customer centers until December 31, 2019. Only the difference is to be paid. A refund of the tickets is not possible.
