réttindaferðar

I’m not sure what you mean by rettindaferðar. Could you clarify the context or field this term belongs to (for example: a legal term in Icelandic law, a sociopolitical concept, a historical term, or a travel/benefits policy)? If you provide a bit of context or a definition, I can write a concise, neutral wiki-style article (under 300 words) in plain text.
