We are looking at purchasing Eurail Global Passes and note that the web site states the following

“Eurail and Interrail Pass holders with a pass valid for Austria can enjoy free public transport on the ÖBB bus network.

The ÖBB Intercitybus (ICB) complements our top long-distance trains in the South of Austria as well as across the border to Italy. During your bus trip, you enjoy the service and the quality you are used to from rail travel.”

Is this bus travel treated as a travel day for the pass or is it in addition to the travel days within the pass?

Does it cover ALL OBB bus routes or just Intercitybus?

Many thanks
