I've been Googling and watching some videos, but I am still confused, and I have got two questions basically. ONE: Can someone tell me the TRANSFER procedure at Oslo Airport? I'll be flying Austrian from my home town (Sarajevo) to Vienna and from Vienna to Oslo, and then SAS from Oslo to Trondheim. What happens with my boarding pass? Both airlines are Star Alliance, so do you think I'll get all passes on my first flight? If I don't, should I get my Trondheim pass in Oslo? Thank you!
