Hi pilatusguy and ranskis ,
Thanks for the tips. Good to know. I'm still newbie here and looking to learn how all this works.
I also saw that when "departing" from France with AF/purchased tickets, in this case i can do a CDG-MUC and Return VIE or even ROM-CDG. etc.
In my initial case this was not possible because my ticket was a "departing Vienna" foreign AF ticket.
Thanks and Speak sooon,
Alex
