Upgrading to get more flexibility
I have a business class ticket (BRU-OSL) that is restricted. I can only make a date change but really would prefer to make a routing change. While trying to make the date change, I see I can upgrade to a fully flexible ticket. So the question is, once I upgrade, can I then be more flexible with routing? Or will the original restrictions apply? Seems like a bit of a weird loop hole if so.
