Ok so my company have upgraded my monthly ICE ticket and Monthly Frankfurt central ticket to a single BC100. I stressed a bit of whether I was able to use it on Frankfurt Local but I have found I can. As well as local in most of the big cities (but only in their central zones. Zuschlags needed outside this zone).
This has the advantage that all my common trips around Germany, most often to Stuttgart, are now free, wohoo.
However as my german is bad i cant find out much more about what else I can do with it. I thought Id start a thread to find out and help out anyone else who wants to know about the BC 100 in future. I looked up BC100 BC 100 and BahnCard 100 on the deep search and not much was there. My main questions at the moment are:
1) Am I now eligible for the ICE Bahn Comfort seats?
2) On my monatkarte for Frankfurt - Aschaffenburg I was able to take 4 people with me between the two places free on Saturdays only. Is there anything similar?
3) On my monatkarte for Frankfurt I was able to take one person and unlimited children with me free after 7pm week days and all day Saturday and Sunday. Is this also gone?
4) Anything else I can now do?
So in short, in school exam terms "Bahn Card 100, discuss"
