In 2023, the Munich Transport and Tariff Association (MVV) began a growth phase, increasing its membership from eight to eighteen, which includes fifteen districts and three independent cities. Plans are in place for further additions next year, particularly the district of Ostallgäu and the independent city of Kaufbeuren, with the potential for the districts of Altötting and Traunstein to join by 2028.

However, a significant merger that has long been anticipated—the joining of the MVV with the Augsburg Transport Association (AVV)—is currently stalled. During a press conference, MVV Managing Director Bernd Rosenbusch announced that the membership from Augsburg would be postponed indefinitely, attributing the delay to funding challenges. Previous projections had suggested that this merger could occur as early as 2025, but consistent issues around adequate financial support from the State of Bavaria for these communal costs are preventing progress.

The situation highlights the complexities of public transportation financing in Germany, where local and state governments often play pivotal roles in funding and expanding transit services. The delays in merging the MVV and AVV not only affect regional transport integration but also raise concerns about the responsiveness and commitment of state authorities to support necessary infrastructure development for growing urban populations.
