Cheap flights/trains from Brussels to Oslo
 

I am posting on behalf of my friend, who is French.

He is a university student and wants to visit some friends in Oslo for the weekend from August 5th to August 7th.

However, he has told me he only wants to spend up to €180. I have been on nearly every single airline website that does this route, only to see that the flights are ridiculous prices of €800 or more.

He is becoming desperate as not many airlines operate this route.

I found a train that goes from Brussels to Amsterdam. From Amsterdam there is a train to Copenhagen, and lastly a train to Oslo. I can't seem to find much information on this but I really want to help my friend to see his friends. They don't have much money so they can't visit him.

Any help is appreciated.
