Let me add that any ticket for long distance trains needs to cover a trip of more than 100 km (one way) in order to include a the City option - an ICE ticket to Köln Hbf, for example, wouldn‘t include that.
By the way, I think I remember that, as the Skytrain was first opened (and frequently swapped for a bus due to technical problems), they stated that any railway ticket (and parking tickets for P4-P5-P6) would be valid for the Skytrain - however, that was before the City option had initially been introduced (for BahnCard holders). Did they actually change that rule?
