Where is the Deutschlandticket valid (and where not)?

Your Deutschlandticket is your flat rate for nearly all public local transport across Germany. Here is a simple overview:

Where your ticket IS valid:

• On all buses in local transport (city bus, regional bus)
• On all trams
• On all commuter trains (S-Bahn) and subways (U-Bahn)
• On all regional trains (RE and RB) -- exclusively in 2nd class.

This applies nationwide, regardless of which transport company operates the line.

Where your ticket is NOT valid:

• On long-distance trains (e.g. ICE, IC, EC, or ECE)
• With private operators such as FlixTrain or FlixBus
• On purely tourist transport (e.g. museum railways or sightseeing buses)
• In 1st class on any train.

Good to know (special cases):

• On-demand buses: You can generally use them, although many transport associations charge a small "comfort surcharge" that is not included in the ticket.
• Trips abroad: The ticket is generally only valid within Germany. There are a few exceptions for certain cross-border routes (e.g. to Salzburg, AT or Venlo, NL). Please check with the local transport association about these specific routes in advance.
