How hvv Any calculates the cheapest ticket for you:

Over the course of the day, hvv Any collects your fare-relevant journeys based on the data you have submitted.
After the operating day has ended, the system checks which tariff product or tariff products cover all your journeys most favourably for you. These are then assigned to the respective journeys and invoiced to you.
You can also get an overview of this under the menu item "my journeys" in the app.
The calculation takes place between 06:00 - 08:00 the next day.
