Just want to add, that you can but a oneway ticket from Dresden to Munich on Lufthansa.com and a oneway ticket from Munich to Berlin.

Just in case, if this is an option as well (I know, you daughter is in Dresden, but this would maybe save you from the hassle of Berlin - Dresden - Munich (Neuschwanstein) - Munich - Dresden - Berlin.


(for the record Air Berlin is flying Munich - Berlin as well)
