1. Can someone give an overview of the bahn.bonus and the BahnCard program?
I understand that you get either a 25% or a 50% discount but how do you apply, what info do you need to provide, what fares can the discount be applied to, etc?

2. I'm going to MUC and may be going to Salzburg, Innsbruck and/or Augsburg. Later this year I'll be coming back and traveling extensively around the northern parts of Germany (CGN=>TXL and then to FRA). I'm trying to figure out whether its better to buy individual tix for the first trip and a Railpass for the second trip or to buy a BahnBonus and individual tix. I'm under 25 if that makes a difference (I know it may for DB).

Thanks!
